Suspension clamp for OPGW cable

Specifications

Suspension clamp

Application

OPGW cable will be hung in the transmission line towers. Clamp can reduce the cable hanging points in the static stress, enhance the ability of cable vibration, the dynamic vibration suppression of wind stress; and keep the cable bending does not exceed allowable values, so that bending stress fiber cloth produced. After installation of the cable clamp, does not produce harmful stress concentration, fiber does not produce additional loss.

Structure&Materials

This product is a combination of clamp, with a suspension head (each head by a rubber clamp suspension, aluminum plates, U-card, bolt, spring cushion, flat pad, nut, pin closed form), outer preformed wire, retaining Preformed wire line combination.

Directly  preformed armour rods  wrapped around the cable surface, providing protection for the cable and stiffness, protecting the line wire is preformed rubber grip clamp inserts, outer middle preformed wire cutter type of rubber from the press and hold the drum clamp, aluminum Maintain its external splint.

U-card:

Made of high strength aluminum alloy.

Aluminum splint:

Made of corrosion-resistant aluminum die casting, the aluminum chemical stability, good resistance to atmospheric corrosion and has good mechanical properties.

Rubber clamp:

Be made of quality rubber and center strength member ,has anti-ozone resistance, chemical resistance, weather aging, with high and low temperature performance, and high strength and elasticity, the smaller deformation.

Bolt,Elastic pad,Flat pad,Nut:

Hot galvanized Standard Parts

Closed bolt:

Power standard parts

Preformed armour rods:

Aluminum alloy wire, high tensile strength, hardness and good flexibility and strong anti-rust capability, in bad weather conditions long-term use.

Preformed outer rods:

Same with preformed armour rods.

link fitting:

Shackle,U-bolt,UB-clevis,ZH-hanging ring are all power standard parts.
