Control cable for nuclear power station

The utility model provides a control cable for a nuclear power station, which is characterized in that a double-layer insulator is arranged outside a conductive wire core; an irradiation-resistant halogen-free flame-retardant belt, a shielding layer, a combined protective layer and an irradiation-resistant outer protective sleeve are arranged outside the wire core from inside to outside; and a non-hygroscopic halogen-free flame-retardant filling is arranged between the halogen-free flame-retardant belt and the insulated conductive wire core. The control cable adopts the double-layer insulation and the protective layer, and meanwhile utilizes the irradiation-resistant flame-retardant insulation and the irradiation-resistant flame-retardant outer protective sleeve, thereby having irradiation resistance and good flame-retardant performance; and the novel insulator and the protective sleeve materials resist heat and have long service life, thereby conforming to environmental-friendly RoHS of EU, and having low smoke and no halogen. The control cable is applicable to the nuclear power station.
