What is an ADSS Fiber Optic Cable?

All-dielectric self-supporting optic cable is another name for ADSS fiber optic cable. There are two modes in optical fiber; single-mode and multimode fiber.

The self-supporting type indicates that the optic cable&#;s reinforcing member can withstand its weight and external load, has high mechanical strength, and can withstand the strong electric environment&#;s impact.

A comprehensive transmission circuit infrastructure with high-reliability performance is provided by the ADSS fiber optic cable system, which includes cables, suspension, dead-end, and termination enclosures.

What are the benefits of an ADSS cable?

In most cases, ADSS cable will provide an efficient and optimal solution for aerial cabling or outside plant (OSP) deployments.However, the most remarkable advantages of optical fibre are:

• Its dependability and low fiber cable price.
• A fiber optic cable is strong enough to allow installation lengths of up to 700 meters between support towers.
• ADSS cable is lightweight and small in diameter to reduce the load on tower structures caused by cable weight, wind, and ice.
• To maintain low optical loss throughout the cable&#;s life, the internal glass optical fibres are supported with no strain in the cable&#;s design.
• The cable is jacketed to protect the fibers from moisture.
• The jacket also shields the polymer strength elements from the effects of UV light from the sun.
• Circuits up to 100 km long are possible without repeaters using single-mode fibre cables and light wavelengths of or nanometers.
• A single cable can transport up to 144 fibers.

Structures of ADSS Cable

ADSS cable structures are classified into two types of optical fibre:

1. Central Tube Design

The fiber network in this design is placed in a PBT loose tube that is filled with water-blocking material. Then, depending on the desired tensile strength, they are wrapped in aramid yarn and extruded with a PE (110KV electric field strength) or AT (100KV electric field strength) sheath. Of the two fibre cable types, thisstructure has a small diameter and is light in weight, but it has limited lengths.

2. Stranded Structure Design

In a stranded structure design, the water-blocking grease and inner optical fibers are added to the loose fiber tube, and different loose tubes are coiled around the central reinforcement (usually FRP). The rest of the fiber optic wire is essentially the same as the central tube structure.

Between both fiber optic cable types, the lattercan produce a longer fibre length. Despite its large diameter and weight, an ADSS fiber optic cable with this structure is better suited for long-distance applications.

ADSS Cable Installation

ADSS fiber optic cable or types of OFC cable is a self-supporting fibre network cable that does not require any support when moving power from one location to another. These cables, while self-supporting, are typically installed on utility poles and power lines with the help of a fiber cable connector. Among ADSS fibre optic installation accessories are:

• Tension assemblies (clips),
• Optical distribution frames (ODFs)/optical termination boxes (OTBs),
• Suspension assemblies (clips),
• Outdoor junction boxes (closures),
• Optical termination boxes,
• any other

ADSS fibre anchoring clamps can be conveniently utilised during fiber optic cable installation as individual cable dead-end clamps at end poles or as an intermediate (double dead-end) clamp.

Applications of ADSS cables

ADSS cable was originally derived from military lightweight, rugged deployable (LRD) fiber wires. The advantages of fibre optic cable are many.

ADSS fibre optic cable is now used in aerial installations for short-span, typically on roadside power distribution poles, thanks to continuous improvements in technology such as fiber cable internet. Because it is non-metallic, the ADSS cable is ideal for applications near high-voltage power distribution lines, for which it has become a standard.

Circuits up to 100 km long are possible without repeaters using single-mode fibre and light wavelengths of nm or nm. ADSS OFC cable was typically used in 48 and 96 cores.

Preformed Tension Clamp: The Complete Guide

Are you looking for a secure and robust installation for your power line cables?

If so, you are in the right place because the information in this article will broaden your scope of knowledge.

Stay tuned as we give you all the details you have ever wanted to know about the preformed tension clamps.

What is a Preformed Tension Clamp?

A preformed tension clamp is also known as dead-end cable grips or preformed dead end.

Preformed tension clamp

You will find it in everyday use on communication OPGW cables, ADSS fiber, or OPPC.

It is also an important part of OPGW/ADSS transmission lines.

OPGW fiber cable

The preformed tension clamp and the dead-end grips are similar in appearance but differ significantly in function and specifications.

Apart from that, you will be able to see the difference in the strength requirement and raw materials of the two devices.

The raw materials on the preformed tension clamp are galvanized steel wire or aluminum clad steel.

Manufacturers usually export the galvanized steel preformed tension clamp for use overseas.

Different countries have their rules and standards that govern the manufacture of preformed tension clamps.

This is the reason why many manufacturers are ready and willing to customize a preformed tension clamp for you.

Why You Need a Preformed Tension Clamp

The cable has a particular design and has many functions as listed below.

The dead-end cable grips have a unique design that connects OPGW/ADSS/OPPC to overhead poles or towers.

The preformed tension clamp simplifies this type of connection or installation and keeps the cable inside it safe.

It protects the OPGW/ADSS/OPPC cable from any form of damage caused by the stress points.

It also makes sure that the cable is not damaged and the signal does not disappear during the process of transmission.

Types of Preformed Tension Clamp

The span or the distance between the two towers or poles will determine the kind of preformed tension clamp to use.

Different types of preformed tension clamp

There are three main types of preformed tension clamps namely single grips, double grips, and big grip dead end.

The single grips and the double grips are in use on the ADSS cable.

a) Single Grips

Single grip preformed tension clamps are in everyday use on the ADSS cable.

In case the distance between the two towers or poles is less than 100 meters, single grips will be in use.

This is because it has enough strength to hold cables connected at a span of 100 meters and below.

b) Double Grips

You will also realize that double grips preformed tension clamps are also in everyday use on the ADSS cable.

In case the span or distance between the two poles or towers is more than 200 meters, then the double grip will be in use.

It has more strength than a single grip, and it will be able to sustain this kind of connection.

c) Big Grip Dead End

This type of preformed tension clamp is in use for connections that are over 800 meters long.

In simple terms, you will use it in contexts where the towers or poles are more than 800 meters apart.

It has an extreme grip strength that wraps the cables having big spaces.

The spacing is for the spreading of the main points of strength.

Technical Specification of Preformed Tension Clamp

Some of the key aspects to consider when evaluating preformed tension clamp:

Technical specifications

· Dimension

In case you are interested in making an order for a custom-made preformed tension clamp, include the following aspects.

You will have to add the diameter of the cable, length of the cable, color mark, and number you will need.

Do not forget to mention the preferred weight of the preformed tension clamp.

The diameter is in millimeters, weight in kilograms, length in meters, and strength in kilo-newtons.

· Material Type

The type of material you will require varies according to your specifications.

The principal raw materials you can choose from are galvanized steel wire or aluminum clad steel.  The material type will affect factors such as weight, thickness, and strength of the preformed tension clamp.

· Finish &#; hot-dip galvanization

Corrosion is one of the most significant problems affecting steel and aluminum appliances.

Manufacturers make sure that their products are corrosion resistant by passing it through the process of hot-dip galvanization.

Dipping the material in hot molten zinc makes it corrosion resistant and gives it a polished finish.

· Thickness

The thickness of the preformed tension clamp depends on the diameter and the type of material you choose.

In most cases, the thicker the device, the stronger it will be, and it will hold a lot of loads.

Design

The design of the preformed tension clamp varies significantly according to the type of device you intend to use.

It will also change according to the kind of load and span between the two poles or towers.

This means that you will have a different shape and number of holes when choosing between the three types.

Single grip type will have fewer holes and a completely different design on the two ends as compared to the double grip.

The lock at the ends will also vary due to the kind of weight or load they will be handling.

· Tensile strength

The tensile strength of the preformed tension clamps varies according to the type of device you choose to use.

When selecting an apparatus for use, look at the weight or load it will be handling.

You will choose the big grip dead end if the load is huge and very far apart, usually more than 800 meters apart.

This is because of the more significant the preformed tension clamp, the higher the tensile strength.

The smaller the preformed tension clamp, the lower the tensile strength.
