Do You Want to Understand the Difference Between ADSS and OPGW Fiber Optic Cable?

 

ADSS cable and OPGW cable are often used in power utilities and telecommunications nowadays.In this article, some differences between ADSS and OPGW cables will be discussed.

 

 

 

 

What are OPGW and ADSS Cables?
All-dielectric Self-supporting (ADSS) cable is a type of fiber optic cable that is strong enough to support itself between structures without using conductive metal elements.The cable is designed for aerial transmission and distribution power lines environments. As its name indicates, there are no metallic components and the cable does not require a support or messenger wire, so installation is achieved in a single pass.

 

 

Optical ground wire (OPGW), also known as optical fiber composite overhead ground wire is a dual-functioning cable performing the duties of a ground wire and also providing a path for the transmission of voice, video, or data signals.The cable is designed to be installed on transmission and distribution lines. The fibers are protected from environmental conditions (lightning, short circuit, loading) to ensure the reliability of signal transmission.

 

 

 

 

ADSS

 

VS.OPGW Cables

 

ADSS or OPGW, when dealing with outdoor fiber cabling, might be tough sometimes due to the difference in cabling designs, features, environment, cost, and applications.Let's take look at the main differences between them.

Structure
ADSS cable structure is mainly composed of central strength member, stranded loose tube, water blocking material, aramid yarn, and sheath. ADSS cable structure consists of 2 types: single jacket and double jacket.

 

 

 

OPGW cable structure is mainly composed of an optical fiber unit (stainless steel tube, aluminum-clad stainless steel tube) , and metal mono-filament (aluminum-clad steel, aluminum alloy) peripheral reinforcement. There are 4 OPGW cable types: ACS (Aluminum clad stainless steel tube), stranded tube, central tube, and ACP (Aluminum clad PBT).

 

 

Features
ADSS cable can be installed without shutting off the power, large span lengths,  good performance of tensile strength,  lightweight and small diameter.
OPGW cable provide stainless-steel optical fiber unit with layer stranding structure, aluminum alloy wire and aluminum clad steel wire armored, coated with anti-corrosive grease between layers, heavy load capacity and long span installation.

Installation Position
The installation position is inconsistent - If the wires need to be rewired or replaced due to aging, it is more suitable to use OPGW cables than ADSS cables.Unlike OPGW optical cables, ADSS cables are more suitable for installation in the power distribution and transmission environment where the live wire is placed.

 

 

 

 

Installation Cost
The installation cost of OPGW cable is relatively high, and a lot of money needs to be invested at one time; while the installation cost of ADSS  cable is relatively low, because it does not need to replace the electrical transmission line, and can also achieve free switching.

Applications
OPGW cable is used in the electric utility industry, transmission and distribution of power lines ( i.e., 500KV, 220KV, 110KV voltage grade lines), voice, video, data transmission, SCADA networks, ariel ground wires, and dark fiber leasing.
ADSS cable is used for telecommunications by power utilities, telcos, and private network groups, distribution and high voltage transmission lines, conductors, outdoor aerial self-supporting installation, enterprise OSP networks, broadband, FTTX networks, railways, long-distance communication, CATV, CCTV, computer networks system, ethernet LAN Network, outside plant campus backbone, etc.

Conclusion
ADSS cable is cheaper than OPGW cable and easy to install.However, OPGW cable has high voltage transmission efficiency, and can also be used for telecommunication transmission data to achieve the purpose of high-speed data transmission.Sun Telecom provides all ADSS and OPGW cable products and solutions to the global market.

Parts of ADSS Accessories

Some of the main parts of ADSS accessories include the following:

· Preformed Tension Clamp

Also known as a preformed dead end or dead-end cable grips with a unique design for connecting ADSS/OPGW to overhead poles. It simplifies connections and installations and safeguards the cable it conceals inside it. You can use it to protect the ADSS/OPGW cables from the damage, especially at the points of stress. Besides using it for protection, it will be making sure that the cable transfers power and information without interruption.

· Armor Grip Suspension

The Armor grip suspension has a unique design that reduces the dynamic and static stresses at the point of support. The support intends to protect the strand or the conductor from effects such as that of oscillation. Apart from that, it offers protection to the conductor in support against power and impulse flash overs. It has a recommendation of being better and superior to armor clamp combinations.

This is because it safeguards conductors from compression stress, abrasion, and bending stress.

· Thimble Clevis

A thimble clevis has a special design for use in conjunction with preformed dead-ends on dead-end insulators or suspension type. The thimble's main intention is the provision of a smooth internal contour that prevents the concentration of stress within the loop. The loop where all these connections are in the loop of the dead-end.

The thimble clevis consists of a steel pin linking it through the eye of the insulator it connects. Apart from that, the pin has a humpbacked cotter key that protects and secures the insulation.

· Armor Rod

The armor rod has a special design that protects the cable against abrasion, bending, compression, and flash-over. Apart from that, you can use it to repair damages on aluminum-based conductors and to restore conductors. The primary restoration is on the mechanical strength of the conductors and conductivity of the conductors.

· Downlead Clamp

Downlead clamps have a special design for guiding optical ground wires from the splice box to the top of the pole. They are very easy to install, providing proper space and holds strengths without causing damage to the cables. You can use it on power poles and communication towers to meets all the specified needs of any application you might have.

What is Suspension Clamp? How Does It Work?

 

What is Suspension Clamp? How Does It Work?

 

Industry News    -07-22

 

Electric and telecommunication technology have evolved over time, different tools and devices are invented over time. The two main components of telecommunication are cable/conductor and poles/towers. In order to mount cables firmly on the tower/pole, you need a special device known as Suspension Clamp. The article will discuss: what is suspension clamp and how does it work? So let&#;s get started. 

 

What is suspension clamp? 

So quick question, what is suspension clamp? Also known as clamp suspension is a clamping/fitting device. It is used to firmly attach cable/conductor along a portion of its longitudinal sides onto the tower/pole. It is one of the essential devices in electricity connections. Based on their application, applications and type of cable are further divided into different categories, namely Suspension clamp for ADSS cable, suspension clamp for ABC cable, and Suspension clamp for an overhead line. 

 

How does suspension clamp work? 

Now you know what is suspension clamp? Let&#;s see how does it work? The wire cable fittings are designed to keep in mind the stresses in the overhead cable, which should be kept as low as possible. The suspension clamp for overhead cables also includes a cable trough with a cable channel in which the overhead cable is placed. Then with the help of a metal pressure member and screws, the assembly is tightened. The assembly is firmly attached, thus restricting excessive sway and other oscillations in the cable. Suspension clamp hence successfully clamps the conductor in place for a longer lifetime. 

 

Applications and importance of suspension clamp

Suspension clamps, as already mentioned, are one of the essential elements of telecommunication and electric fittings. Now the question is, what is suspension clamp used for? Due to their robustness and effectiveness as a clamping device, they have a wide range of applications. Some of the common types and applications of wire cable fittings are as follow: 

 

1.Single or double suspension clamp

This type of suspension clamp is used to minimize the static and dynamic pressure of the cable/ conductor. The fulcrum of the suspension clamp disperses the stress to the preformed rod. The fulcrum also protects the cable from any damage. Moreover, the design of a Single/Double suspension clamp is made to provide better grip, thus preventing the conductor&#;s slip. 

 

2.Single suspension set for OPGW cable

Also known as helical suspension. The application is in hanging fiber cables on a straight pole or any tower. They are designed to divert axial pressure and transmit axial load, which keeps the cable from any potential damage.

 

 

3.Double suspension set for OPGW cable

Its application is in clamping OPGW cable to the pole. This type of suspension clamp reduces the static and dynamic stress of the cable at the support point. Moreover, they are also effective in reducing cable bending, thus protecting it from different loads. 

 

 

 

4.Double suspension clamp

They are used to reduce the static stress at the support point of the ADSS cable. The clamp also protects against wind vibration and bending stress. 

 

There are many other types of suspension clamp, such as Midspan/Long span suspension clamp for ADSS cable, short span suspension clamp for ADSS cable, etc. 

 

So what is suspension clamp and its importance? As you already know, what is suspension clamp, right? But can you think of its importance? Well, after reading about its applications, you must have realized the importance of wire cable fittings in electric fittings, especially when you have to clamp the cable to a pole/tower. Suspension fitting is designed to create the strongest link and fitting between cable and wire. Therefore, an enhanced lifespan and efficient working of transmission lines are ensured.

Armor Grip Suspension: The Complete Guide

Armor grip suspension is a unique accessory that is very important for all your telecommunications and electrical needs.

You need to buy high quality and reliable armor grip suspension for efficient and uninterrupted transmission.

In this guide, I will make that process simple and easy for you.

Here, I am going to walk you through basic definition, main components, installation procedures, and technical specifications, among other important aspects.

I want to make it easier for you to choose and buy the right armor grip suspension.

Let&#;s get started.

What is Armor Grip Suspension?

Do you know what this accessory looks like?

Here is what I am talking about:

 

Armor grip suspension

As in the picture above, an armor grip suspension is one of the many suspension clamps used for distribution or transmission systems.

It consists of preformed clamps, wires, nuts, and bolts.

Depending on the unique applications, you can find armor grip suspension made from galvanized iron or steel.

It is also called a preformed suspension clamp or AGS suspension clamp.

They come in unique designs and sizes.

This is always dependent on your application needs.

All you need is to get a reliable manufacturer who can make an armor grip suspension for your needs.

Why You Need Armor Grip Suspension

As I said earlier, armor grip suspension plays an important role in telecommunication and electricity systems.

So, here are some of the main reasons why you need this accessory.

1. It is an Important Accessory for Line Repair Purposes

In situations where conductors have been damaged by bolting clamps, a preformed armor grip suspension can be used for repairs.

Armor grip suspensions can be installed over preformed armor rods.

This restores and extends the lifespan of conductors.

2. Armor Grip Suspension Plays a Crucial Roles in Line Angles

Experts recommend that the best angle for single support AGS is 30 degrees.

That is why the armor grip suspension, double assembly is best for angles between 30 degrees and 60 degrees.

Armor grip suspensions can be used for:

• ACSR conductors
• Copper conductors
• Fir ACC
• Galvanized steel conductors
• SC/AC conductors
• AAAC

They can also be divided into single or double AGS suspensions.

Preformed armor grip suspension units are designed for use on various types of materials and conductor constructions.

This unit is also designed to lessen static and dynamic stress at support points.

It ensures that conductors are safeguarded against conduction motion effects.

It works by protecting conductors in support areas against power flash-over and impulse arching.

When you compare them to normal suspension clamps, preformed armor grip suspension units are superior to bolted types.

Of course, this is when it comes to safeguarding conductors from compression and bending abrasion or stress.

To have corona onset and RIV specifications met for most extra high voltage apps, you should use these products.

How to choose for different spans?

Less than 100m spans: choose a preformed suspension clamp without an inner armor grip. The rubber wraps the ADSS cable directly, the aluminum clad connect the U clevis to hang up the ADSS cable.

100-200m span: suspension clamp assembly consists of inner armor grip, rubber, aluminum clad, bolt and nut. The vertical grip strength is 30kn. The inner armor grip wraps the ADSS cable to reduce the static and dynamic stresses at the support point so that the conductor is protected against the effects of conductor motion.

200-800m span: The difference with 100-200m span is the suspension clamp assembly added outer armor grip. The big touching space between the Armor grip suspension and ADSS cable will reduce the dynamic stresses at the support point.

You can review the summary of this explanation in the table below:

Installing Armor Grip Suspension on Pole Line

You need to follow the right procedures when installing armor grip suspension.

Although this process is not complicated, you need to get it straight so that you can complete it and see its maximum use.

1. Start by plumbing insulator strings and have conductors marked at its sheave center. You can make use of a felt pen. Make sure you never scratch the conductor.
2. Lift the conductor beyond the rod ends to permit the right application clearance.
3. Ensure AGS neoprene center marks align. The inserts made with a center mark on the conductor and have a thin layer of tape used to hold it in its place.
4. Have AGS rod centered on insert. Make sure the right amount of rod length is applied. This is important to ensure it stays on the conductor. Make sure rods aren&#;t distorted.
5. Apply the single rod carefully. The rod&#;s curvature should follow the neoprene insert&#;s contour. Be sure that there is no space between the insert and the rod.
6. Have all excess rods applied evenly around neoprene inserts. Ensure no rods are crossed. Each rod can be totally applied or, all rods can be fixed incompletely.
7. Have the AGS housing&#;s two halves on either side of the center assembly. Then have the AGS strap slid into its position and with your hand&#;s heel, firmly tape it into place.
8. Have the housing&#;s ears spread and the strap tapped back into place. This will ensure holes are aligned in order to have bolts easily aligned.
9. Have nuts tightened until the lock washer (become approximately flat). Make sure you do not over tighten the nut. Also, try not to have the ears squeezed against the fitting.
