Shijiazhuang Paerpu Import and Export Trading Co.,Ltd is a professional optical cable China manufacturer, a new technology enterprise which develop, exploit, manufacture and sell Preformed tension clamp/armor rods equipment, Preformed ADSS & OPGW Cable, Preformed Products for Transmission & Distribution and electrified railway fittings.
1.Introduction of optical cable
• optical cable namely called OPGW cable, which is a type of cable structure with composite of optical transmission and overhead ground wire for power transmission.
It’s working in power transmission line both as optical fiber cable and overhead ground wire which can provide protection of lightning strike and conducting short circuit currency.
• The OPGW consist of stainless steel tube optical unit, aluminium cladding steel wire, aluminum alloy wire. It has central stainless steel tube structure and layer stranding structure. We can design the structure according to different environment condition and customer’s requirements.
2.Features:
• Stainless-steel optical fiber unit of central loose tube or layer stranding structure
• Aluminium alloy wire and aluminium clad steel wire armored
• Coated with anticorrosive grease between layers
• OPGW can support heavy load and long span installation
• OPGW can meet the ground wire‘s requirement of mechanical and electric by adjusting proportion of steel and aluminium.
• Easy to produce the similar specification of exist ground wire can replace the exist ground wire
3.Application properties:
OPGW cable is mainly used in 500KV, 220KV and 110KV lines, limited by power cut, security and other elements, mostly used in new lines.
It's applications are: high pressure over110kv, with a longer span (usually over 250M);
