Central Type Overview
Central Tube Optical Ground Wire (OPGW)

中心束管式OPGW

Description of OPGW:
The Central Tube Optical Ground Wire (OPGW) 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.

Standards:

ITU-TG.652 Characteristics of a single mode optical fiber
ITU-TG.655 Characteristics of a non-zero dispersion -shifted single mode fibers optical
EIA/TIA598 B Col code of fiber optic cables
