Product Description

Composite Overhead Ground Wire Cable OPGW

Product introduction

OPGW is a kind of overhead ground wire containing optical fiber, which has multiple functions such as overhead ground wire and optical communication. It is applicable to new aerial power route to satisfy the needs for big conductors and high voltage transmission, and is used to conduct large fault short circuit current to provide anti lightning protection. It is mainly used on 500KV, 220KV and 110KV voltage level lines. It is mostly used on new lines due to the influence of line power outage and safety.

Product structure
 

Layer stranding structure	Central tube structure
1. Big diameter and more optical fiber.	1. Small diameter and light weight, small short-circuit capacity.
2. Big tensile strength and short-circuit capacity, arrive the best balance of mechanical and electrical properties.	2. Optical unit forms appropriate primary optical fiber extra length.
3. One or more optical unit.	3. Characteristics of tension resistance, torsion resistance and side pressure resistance are good enough.
4. Best design of stranding, obtain secondary optical fiber extra length.
5. Strands piles can be two or three; the wire can be ACS wire and/or the combination of aluminum alloy wire and aluminum wire.
