Structure Design
Applications:
Reconstruction of old power lines and low voltage level lines.
Coastal chemical industrial areas with heavy chemical pollution.
Main Features: (addition to the features of stainless steel tube OPGW cable)
Can meet high electrical performance requirements, and have excellent corrosion resistant performance.
Applicable to coastal areas and areas with heavy pollution.
Short-circuit current has little effect on the fiber.
Applicable Voltage Range:
Power lines with voltage level of 220KV and below.
