Preformed guy wire clamp

拉线用预绞式耐张线夹 Preformed guy wire clamp

功能用途/ Function and Purpose

The clamp is mainly applied to fix the guy wires of the various types of poles or towers. It can replace the wedge clamp and U-T clamp used at present.

产品特点/ Product characteristic

²  Guy wire is finely protected because stress is equally distributed in large touching area without intensive stress pivot.

²  The grip is more than 95%RTS of guy wire.

²  The materials of clamp selected good quality materials to against corrosion.

²  Simple structure is convenient for installation. Manual operation on the spot without any requirement of the special tools.

²  Good resistance to vibration performance.

²  The revolving directions of the clamp shall be kept consistent. Generally, the standard dead-end clamp adopts right rotation. Please order in advance if you require left rotation.

使用须知/  Consideration

²  Select suitable dead-end clamp according to the guy wire specification.

²  The clamp can be used only once.

²  This product can be only operated by trained and skilled worker.

²  Be careful during working on live line or accessories to prevent electric shock.

 

应用实例/ Application



The suspension clamp of electric power fittings is divided into old ship type clamp and pre twisted suspension clamp. Today we are going to talk about the suspension clamp in the pre twisted power fittings, which uses the connecting hardware to hang the optical cable on the transmission line tower. The use of the pre twisted suspension clamp can reduce the static stress at the suspension point, help the cable damp and restrain the dynamic stress of the wind vibration, and protect the cable.


The pre twisted suspension clamp is used for the connection of ADSS optical cable, OPGW optical cable and various conductors in the tangent tower. Its components are:


1. Aluminum clamp assembly: the aluminum clamp used for pre twisted suspension clamp has the characteristics of corrosion resistance, good chemical stability, atmospheric corrosion resistance and good mechanical properties.


2. Rubber clamp assembly: pre twisted suspension clamp rubber clamp has the characteristics of ozone resistance, chemical resistance, weather aging resistance, high and low temperature performance, high strength, high elasticity, small compression deformation, etc.


3. Hot dip galvanized parts of power fittings: bolts, spring washers, flat washers, nuts, etc. Closure pin: power standard.


4. Preformed wire protection: the aluminum alloy wire rod made according to the predetermined mechanical properties and chemical composition has the characteristics of high tensile strength, high hardness, good elasticity, strong rust resistance, etc., which can be used for a long time in the harsh climate environment.


5. Outer layer pre twisted power hardware: the same as the protection wire pre twisted.


6. Power connection hardware: U-shaped lifting ring, U-shaped screw, UB type hanging plate, Zh type lifting ring.


The standard configuration of double hanging clamp includes protection rod pre twisted wire, outer layer pre twisted wire, two pairs of lifting heads, two pairs of PS hanging plates, double hanging connecting plates, u-rings and U-screws. The connection part is optional.
