ADSS Preformed Suspension Clamp

ADSS Suspension Clamp

Suspension clamps are also called fixture suspension or suspension fittings. According to the application, the suspension clamps are divided into ABC optical cable suspension clamps, ADSS optical cable suspension clamps, and overhead line suspension clamps.

ADSS Optical Cable Suspension Clamp

Suspension cleats for ADSS cables are also known as prefabricated suspension cleats. Prefabricated catenary clamps that function the same as ordinary catenary clamps are designed to suspend conductors or ground wires in a vertical direction.

Huaneng prefabricated suspension clamps are suitable for high voltage above 220kv. Unique features of prefabricated suspension clips:

Effective protection of conductors
Avoiding Electricity Waste Due to Corona
easy installation
Prefabricated suspension clamps are designed to protect ADSS (All Dielectric Self Supporting) cables from sloshing caused by wind currents. Suspended clamps are widely used in transmission lines, towers or power distribution systems.

The distance between the two towers is called the span. For short spans, prefabricated suspension clamps with O-rings are often used. This kind of suspension clamp has the characteristics of lightest weight, convenient installation, and can protect ADSS optical cable more effectively.

For mid-span and long-span, there is also a prefabricated suspension clamp that is aluminum-clad. The Armor Clip Suspension connects with U-Clips to hang cables. Aluminum-clad suspension clamps support and protect ADSS fiber optic cables from bending damage.

According to the span, the short span adopts single suspension clamp, and the long span adopts double suspension clamp.

Composition: inner pre-twisted wire, the outer pre-twisted wire, rubber insert, cast aluminum shells, right-angle shackle, U-type shackle.

Purposes: supporting cable, make the ADSS hang on the tower.

Features:

a, stress on average, no concentration stress, protect cable better.

b, good dynamic stress. It can provide enough grip strength(14%RTS)

c, rubber clip block make abrasion low .

d. rounded end improve the corona voltage

e. excellent aluminum alloy improve the mechanical and resist-corrosion function, extend life.

Technical requirements: meet the DL / T 766-2003 ADSS with the preformed helical fittings technical requirements and test methods.

Applications

The preformed ADSS drape clamp is the connecting hardware for ADSS cables suspended from transmission line poles (towers). It reduces the static stresses at the support points, improves the vibration resistance of ADSS cables and buffers the dynamic stresses of wind vibration.

Ordering Information:

A. Choose the suitable XC suspension clamp according to the outer diameter, span, rated tension strength of ADSS cable etc. parameters

B. the quantity configuration: 1 set / line tower.

C. if the clamp need to install the corona coils and vibration damper, the inner performed wire need to prolong

D. clamp strength: 30KN, 50KN, 70KN etc.

Structure and materials.

Shell - Made of corrosion resistant cast aluminium alloy, good stability, good corrosion resistance and good mechanical properties.
Rubber inserts---Consisting of high-grade rubber and central reinforcement components, the rubber inserts are ozone resistant, chemical resistant, weather resistant, with high and low temperature performance, high strength and elasticity, and small compression deformation.

Bolts, flat washers, spring washers, nuts, split locks, disconnectors - standard parts for electricity.
Internal preformed bar --- customised aluminium alloy wire according to mechanical properties and chemical composition, with high tensile strength, hardness strength and excellent elasticity, strong rust resistance, can be used in bad weather long-term health) condition.
