Cables must be designed for the worst-case combinations of temperature, ice load, and wind. On long spans where utilities already experience caused by sustained high wind, dampers may need to be installed on ADSS cable also. ADSS (All-Dielectric Self-Supporting) fire-resistant fiber optic cable is a specialized optical transmission solution designed to withstand high temperatures, open flames, and fire hazards while maintaining stable signal transmission. Non-metallic, UV-proof, and temperature resistance from -40°C to +70°C. OPGW (Optical Ground Wire) integrates function of grounding with fiber communication. GYFTZY (non-metal flame-retardant fiber optic cable) is strictly not a special fiber optic cable for our power fiber optic cable. But when our power optical cable line enters the substation, the substation has strong current occasions, and the requirements for lightning protection and flame.
