OPGW Product Description
Central loose tube type
The fibers is placed loosely in a sealed and water resistant stainless steel tube filled with water blocking gel. This tube provides protection to the fiber during installation and operation under severe environmental conditions. Aluminium layer over the tube is optional. The stainless optical tube is located at the center of the cable protected by single or multiple layers of aluminium clad steel and aluminium annoy minium clad steel ed trapezoidally around the optical unit to provide compact construction. The metallic mechanical strength to withstand severe installation and operating conditions, while achieving conductivity to controltemperature rise during short circuit conditions.
Multi loose tube ty
Multiple loose tube type
The fibers is placed loosely in a sealed and water resistant stainless steel tube filled with water blocking gel. Two or three stainless steel optical tubes are helically stranded in the inner layer of a multiple-layer strandard cable. The multiple loose tube type is designed mostly for very high fiber count requirement over 48 with the maximum fiber count reaching 144. The multiple loose tube type can meet the requirement of huge cross and large current capacity.
Application
1.The Optical fiber composite ground suitable for installation on new power h
double function of ground nication. Especially for installation on normal voitage and
extra highvoltage power GW can replace conventional ground wer
increasing fiber communication function. They conduct short circuit current and provide lightning resistance.
2. OPGW cable is mainly used in 500KV, 220KV and 110KV mited by power cut, security and other used in new s applications are:high pressure over 110kv, with a longer span (usually over 250M).
