OPGW optical cable is primarily used on 500KV, 220KV, and 110KV voltage level transmission lines. It is particularly suitable for new line construction and aerial ground wire replacement applications.
Designed for installation on aerial transmission towers with operating temperature range of -40°C to +70°C and minimum bending radius of 25 times the cable diameter.
OPGW cables provide enhanced reliability, superior mechanical performance, and cost-effective integration of ground wire and fiber optic communication functions. The composite structure offers electromagnetic interference protection and eliminates the need for separate communication line installation.
