Electric Power Fittings Strain Clamp for Opgw

Preformed Strain Clamp for OPGW
1. Function:
Clamps can be used in the main and branch distribution line
Of bare overhead conductors and insulated wire. It can replace
The commonly used line Clamp.
2. Features:
A, Clamp structure is simple, easily installed
B, 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.
C, The clamp distribute the stress uniformity, improved ability of aseismatic without any damage on cable.

3, Structure&Materials
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.
