OPGW Ground Wire Cable 36 48 72 144 288 Core For Tower 220KV Line Construction
OPGW Ground Wire Cable
,Tower OPGW Ground Wire Cable
Product Description:
optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and telecommunications. An OPGW cable contains a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire. The OPGW cable is run between the tops of high-voltage electricity pylons. The conductive part of the cable serves to bond adjacent towers to earth ground, and shields the high-voltage conductors from lightning strikes. The optical fibers within the cable can be used for high-speed transmission of data, either for the electrical utility's own purposes of protection and control of the transmission line, for the utility's own voice and data communication, or may be leased or sold to third parties to serve as a high-speed fiber interconnection between cities
Main features:
1. Highquality standard design, testing and production, using Class A materials to ensure long-term reliability；
2. Easy maintenance, easy line span, its mechanical properties can meet the large line span; The outer layer of OPGW is metal-armoured, which has no effect on high voltage corrosion and degradation；
3. The construction of OPGW must be power outage, resulting in greater losses, so the construction of high-voltage lines above 110kv must use OPGW;
4. OPGW cable is mainly used for 500KV, 220KV and 110KV 35KV lines, limited by power failure, safety and other factors, mostly used for new lines；
5. Sealed stainless steel tube provides excellent moisture and extreme environmental protection .
