The preformed suspension clamp is designed to reduce static and dynamic stresses at the support point, thus protecting the conductor or strand from vibrations. It also protects the conductor in the support from impulse and power flashover. There are many different types and structures of preformed suspension clamps, such as double suspension set for ADSS, double suspension for OPGW, single suspension for OPGW, etc.

 

OPGW suspension clamp is used to connect OPGW cable and pole (tower), reduce the static stress of support point on OPGW cable, increase the vibration resistance of ADSS cable, buffer the dynamic stress of wind vibration, and ensure that the bending of fiber optic cable does not exceed the allowable value so that the fiber optic cable does not generate bending stress so that the fiber does not generate an additional loss in the fiber optic cable after installation.

 

ADSS suspension clamp is the connecting hardware for ADSS cables suspended from transmission line poles (towers). It can reduce the static stress of the support point, improve the vibration resistance of the cable, and buffer the dynamic stress of wind vibration. As well as ensure that the bending of the optical cable does not exceed the allowable value so that the optical cable does not produce bending stress the optical fiber will not produce an additional loss optical cable.

 

 

 

What are the types of preformed suspension clamps?

1. Suspension Set for ADSS pre-twisted wire with single-and double-twisted wire two kinds of pre-design, single-storey pre-twisted threads within the file folder for the 400m distance connections, double the pre-twisted threads are generally used for large files from the folder (within 1000m) the connection between, may be based on the actual need to select a different installation method.

 

2. Double Suspension Set for ADSS is mainly used for the large height difference, span more than 800 meters or unilateral overhang angle is 30 º -36 º line tower connection.

 

3. Double Suspension Set For OPGW with the use of double-Suspension design, including the inner and outer pre-twisted wire to connect two sets of hanging head and matching fittings. mainly for the large height difference, span more than 800 meters or unilateral overhang angle is 30-36 º line tower connection.

 

4. Suspension Set for OPGW used primarily for straight-sided drop tower, or less than 15 º line tower connection.

 

 

 

Features

(1) Retention force of 10%-20% or more of RTS can be achieved without stress concentration and vibration stress.

 

(2) Superior alloy aluminum improves mechanical and corrosion resistance.

 

(3) Extended life span.

 

(4) Protects the cable well.

 

 

What is the preformed suspension clamp used for?

1、Used to reduce static stress at the point of conductor suspension and to provide greater protection for conductors from dynamic stresses caused by wind and sand vibrations.

 

2、Provide protection to conductors against shock and flashover.

 

3、Protects conductors from abrasion, bending and compression stresses. Spiral dangling wire clamp fittings provide better protection than armored clamp assemblies.

 

4、Installation line angle up to 30 degrees and above, by using the double unit, up to 60 degrees.

 

5、For proper performance and personal safety, be sure to select the proper size and preformed armored bars and clamps according to conductor size before use.

 

6、Dead ends are precision devices and should be stored in covered cardboard boxes and handled with care to ensure proper performance.

 

 

 

Safety precautions for preformed suspension clamps

1. Preformed suspension clamps are designed for single (one-time) use and specific applications.

 

2. The preformed suspension clamp is intended for use by trained craftsmen only. This product should not be used by anyone unfamiliar and untrained in its use.

 

3. When using this product to work in an energized line area, special care should be taken to prevent accidental electric shock.

 

 

 

Different countries have their own rules and standards to manage the manufacture of prefabricated suspension clamps, so as an experienced manufacturer of prefabricated tension clamps, we can customize suspension clamps and OEM according to customer requirements.
