Description
OPGW is a type of cable structure with composite of optical transmission and overhead ground wire for power transmission.
Working in power transmission line both as optical fiber cable and overhead ground wire
which can provice protection of lightning strike and conduction short circuit currency.
It consists of stainless steel tube optical unit, aluminum cladding steel wire and aluminum alloy wire.
It has tow types of structure:central stainless tube structure and layer stranding structure.

Standards
IEEE -1138, IEC60794-4-1, IEC60793, ITU-T G. 652, ITU-T G. 655, IEC60794-1, DL/T 788-2001, YD/T 980-2002

Technical parameter
1.Over all diameter (mm): 12~18mm
2.Fiber count: 24~144fibers
3.Fiber optical tube: Laser welded stainless steel
4.Armore type: Aluminum-clad wire or aluminum-alloy wire
5.Unit weight (kg/km): 350~900kg/km
6.Short circuit current capacity: Up to 200kA2. T
7.Rated tensile strength (RTS): Up to 130KN

Application
Suitable for installation on new power lines with double function of ground wire  and communication, especially for installation on normal voltage and extra high voltage powre lines
Replace old power line with increasing fiber communication function.

Features
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.
