从China供应商批发进口Central Stainless Steel Tube Opgw — FOB条款

Description The central stainless steel tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. are the most widely used cables ,their design is fully adapted to the most common electric line needs. Characteristic: 1. High quality standards for designing, testing and producing with grade A materials available to ensure long-term reliability . 2. Engineering support supervising and providing its own line of accessories hardware . 3.Seal stainless steel tube superior protection to the fiber optical to moisture and extreme environmental conditions such as lightening 4. To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing high pressure line over 110kv; 5. Apply to the transformation of old lines.
