Product Features
Overhead insulated cables have advantages such as simple structure, excellent mechanical and physical properties, outstanding electrical performance, and resistance to environmental factors and UV radiation. Due to the insulation material used, which is a weather-resistant special overhead insulated cable material, the long-term allowable operating temperature of the cable reaches up to 70℃ or 90℃, and it has excellent electrical insulation performance with a volume resistivity of over 1.0×10^12Ω·m. During installation, using overhead insulated cables can reduce installation gaps, save corridor space, and decrease voltage drop; during use, it can reduce the occurrence of power supply accidents and ensure personal safety.
