Abstract
The invention provides a halogen-free flame retardant insulated power cable. Insulated wire cores are of a 3+2 core structure. Each insulated wire core is formed by a copper conductor wire and an insulated layer covering the copper conductor wire, wherein the copper conductor wire is formed by twisting soft copper wires. The space among the insulated wire cores is filled with a halogen-free flame retardant filling material, and the halogen-free flame retardant filling material is wrapped inside a water-blocking band. A composite band is arranged outside the water-blocking band. A shielding layer is arranged outside the composite band. An outer halogen-free flame retardant sheath is arranged outside the shielding layer. The halogen-free flame retardant filling material and the outer halogen-free flame retardant sheath are both made of a polyphenyl ether composite material. According to the halogen-free flame retardant insulated power cable, the water-blocking band, the outer sheath layer and the like are used as waterproof components, the filling material in the cable is a high polymer material containing rat-proof ant-proof repellent, so that the cable has water tightness and has the functions of preventing rats and ants, and the safety use performance of the cable is improved.
