Galvanized Steel Wire / Aluminum Clad Steel Preformed Guy Grip

Quick Detail:

* Clamp structure is simple,easily installed

* Its legs twisted wire preformed and the formation of air traffic control, rear twist for the preforming  ring.The formation of preformed wire legs wrapped in wire can produce a very strong grip force,  twist the ring to fix the insulator.

* The clamp distribute the stress uniformity, improved ability of aseismatic without any damage on cable.

* Shackle:Hot galvanized steel,U-7,U-10,U-12,and failure load is 70kN,100kN and 120kN.

* Extension Link:Hot galvanized steel precision,and failure load is 70kN,100kN and 120kN.

* Heart-shaped ring tension:Hot galvanized steel precision, and failure load is 70kN,100kN and 120kN.

* Preformed armour rods:Galvanized steel or aluminum clad steel wire, wall stick with emery, increase friction and reduce the pressure on the cable side, and was prefabricated into several sub-beams to prevent installation errors and to facilitate rapid installation.

* Preformed tension rods:Galvanized steel or aluminum clad steel wire, when pre-processing into a bunch, sticking with a solid diamond wall to reduce lateral pressure on the cable under the conditions of increased Clamp grip. Tu preformed wire color-coded tags, to avoid installation errors, for quick installation.

Description:

Materials: galvanized steel wire or aluminum clad steel

Great enhance friction between clamp and cable

Thimble and one shackle are employed to avoid abrasion between cable and clamp

Depending on voltage, ends of individual rods may be either chambered, ball ended or EHV (extra high voltage) ended

EHV end finish is generally only ever required at voltage >330k

Helical fittings may be installed either by hand or by live line methods and are designed to fit on to conductor for which they designed

Without any question of malfunction or misapplication

a. Connecting with pole tower by splicing fittings such as thimble ,the outer stranded wires mainly bear line load.

b. As force transmission units,the inner stranded wires can Partially protect ADSS cable,the main functions include:

   (1) Effectively deliver vertical pressing force to aramid fiber, the tension force bear unit of cable,as to protect cable sheath from damaging for overstress.

   (2) Deliver axial tension force.

    (3) Larger contact area with cable,even stress distribution,no stress concentration point.

c. In the premise of less than ADSS cable side pressure, it has some grip strength, can bear a certain amount of tension.

d.The grip strength for ADSS is more than 95% of cable ultimate tensile strength (UTS),which completely accords with optical cable erection need.

e.To meet the needs of setting up ADSS cable in 10KV city network's distribution line,we produce tension clamp of 15kN grip strength, which has advantages of simple structure,easy installation and low cost.

Specifications:

Preformed Guy Grip is used in the installation of the exposed conductor also used in electric network transmission and distribution and overhead insulated conductor. The reliability and economic advantage is better than the present bolt type and hydraulic compression type Tension Set which now is being widely used in the line.The structure of the Preformed Tension Set is simple , and the pipe structure formed by the two legs of the preformed line would enlace the conductor naturely and would produce a great holding strength. The novel structure and exact design all contribute to the reliability of the conductor tension set.The set is usually made of concentric-lay-stranded Aluminium-clad steel conductors ,galvanized iron wire strands and other materials.

Applications:

Tension clamp is used to connect cable and tension pole or tower

Helpful to protect cable and reduce vibration

Can be used for terminating bare wire or insulated cable in transmission line and distribution line

With special design of clamp, will not produce stress concentration which damage cable

Clamp grip strength is not <95% of rated tensile strength, keep cable properly

Competitive Advantage:

1) The Guy Grip is able to endure the high intension and grip strength. The grip strength of clamp is not less than 95% CUTS.

2) The clamp distributing the stress uniformity, improved ability of aseismatic without any damage on conductor..So that extended the using life of the conductor.

3) It bears the excellence of easy installation and construction, Shorted the working time. Operated this clamp by one person and need the special tool.

4) Easy to guarantee the quality of installation, inspectioned by optic view without special trainning.

5) Prefect corrosion resistance; The same material with conductor promiss that the clamp owned excellent ability of electrochemistry corrosion resistance.
