Everbright supplies quality Galvanized steel wires used as a reinforcing core for aluminum conductor steel reinforced ACSR conductors. ACSR conductors widely used as bare overhead transmission cable, are made with Aluminum alloy 1350-H-19 wires and stranded steel core wire. The core wire size and mechanical properties we supply are as standard quality specified in ASTM B 498 , IEC  60888 , BS  EN 50189.

The steel core wire for the conductor is either single wire or stranded wire of 7 and 19 wires.

For corrsion protection, the ACSR core wire is hot dipped galvanized to A Grade galvanization, while B, C grade zinc coating also upon request. The galvanized steel core wire for ACSR conductor is greased with a purpose for increased anti-corrosion performance. The special grease applied can with stand a high temperature up to 180 ºC.

Number of steel wire used as ACSR core wire: The proportion of steel and aluminium wire in an ACSR conductor varies according to the mechanical strength requirements. We are listing below a list for references.

Packing:
The galvanized steel wire is supplied on wooden drums, with suitable drum dimension for the cutting length of the wire. Also, the drum dimension is approved before delivery by our customers to suit different machine uses.

Everbright uses treated wooden or strong plywood drums, which are strong enough to avoid damage during transportation, handling and storage.

Each drum is with a tag including the supplier name, purchasing order number, box number, wire size, net weight and gross weight.
