光纤复合架空地线(OPGW)

GROUND WIRE(OPGW)

光纤复合架空地线（OPGW-Optical Fiber Composite Overhead GroundWire）是电力系统特有的一种通信光缆。它具有普通地线和通信光缆的双重功能。由一个或多个光单元绞合单层或多层金属单线制成。高强度的金属保护材料（铝包钢）构成OPGW的主要承力部分，低强度的金属保护材料（铝合金、纯铝丝）构成OPGW的传输短路电流部分，具有优良的传输特性。我公司可根据顾客实际条件进行最佳设计。

Composed of single or multi-optical unit of single or multi-layer metallic wires, OPGW-Optical Fiber Composite Overhead Ground Wire is a special kind of communication optical cable used for power system with double lhnctions of both ordinary grounding and communication cables. The major force bearing part of OPGW is made of metallic protection materials of high intensity （aluminum coated steel） while short--circuit current transmission part of OPGW is made of metallic protection materials of low intensity （aluminum alloy or pure aluminum thread） capable of good transmission performance. Our company is able to make optimal designs in accordance with the specific requirements of our customers.
