High voltage cables require transmission control cables to have good electromagnetic radiation resistance, high voltage breakdown resistance, corrosion resistance, moisture resistance and flame retardance. The inner and outer protective layers of YOFC electric high-voltage flame-retardant cable are made of ETFE, TPU, LSZH and other materials, suitable for all optical fibre products, light in weight and good in bending radius, and necessary reinforcing elements are added to improve the tensile and crush resistance of the cable. Several main structural types such as tight buffer optical cable, loose buffer optical cable, stranded optical cable and bundled optical cable can be designed to provide reliable protection for optical fibre according to the application situation, can directly match various system components in the power grid and fully serve the application environment such as power grid control.
According to the requirements of flame retardancy and high voltage breakdown resistance in power environment, YOFC mainly recommends ETFE and TPU sheathing materials.
