Galvanized Steel Wire Strand

The galvanized steel wire strand is used for overhead ground lines or electrical power transmission lines. Stay wire or guy wire strands are produced for use with poles, towers, or any other form of guying.

Its low cost and ease of production makes galvanized steel wire ideal for mass produced corrosion resistant wire products,which is indispensable in industrial, agricultural.

Construction

Concentrically stranded Galvanized steel wire strand available in class "A", "B" and "C" galvanizing, "A" being the least heavy and "C" being the most heavy. Manufactured without welds per ASTM A-363 or with welds per ASTM A-475. Strands are formed to remain substantially in place when severed.

Zinc-coated grade of steel strand wire /guy wire : Class A ,Class B and class C.

Standards

Copper Clad Steel Wire

Copperweld is for use as earth conductor for overhead transmission and distribution lines (OHTL) of electric power. The unique structure of copper clad steel wires provides perfect grounding solution of high strength, good electrical conductivity and property of corrosion-resistant. It is a good replacement for alumoweld and galvanized steel guy wires.
