Stranded OPGW

Product Introduction

    The stainless tube is stranded by double or three layers of aluminum clad steel (ACS) wires or mix ACS or mix ACS wires and aluminum alloy (AA) wires.

Characteristic:

1.The stainless tube is stranded by double or three layers of aluminum clad steel (ACS) wires or mix ACS or mix ACS wires and aluminum alloy (AA) wires.

2.Larger tensile strength and short-circuit current capacity to reach a better balance of electrical and mechanical performance.

2.The amount of stainless steel tube could be 1,2 or 3(max. at present);

4.Optimum stranding design to reach a suitable secondary fiber excess length;

5.The stranded layers could be double or three layers of aluminum clad steel (ACS) wires or mix ACS wires and aluminum alloy (AA) wires.
