Abstract
The utility model discloses a voltage-and-high-temperature-resistant antistatic mobile cable used for a coal mine. The cable comprises multiple groups of conductor inner cores. Each conductor inner core comprises three soft copper wiring harnesses which are arranged in a triangular shape. Inner insulating layers wrap the soft copper wiring harnesses. Inner sheath layers wrap the inner insulating layers. The multiple groups of conductor inner cores are extruded together through an outer insulating layer. Unvulcanized semiconductive rubbers are filled between the multiple groups of conductor inner cores and the outer insulating layer. A wrapping layer is arranged outside the outer insulating layer. A current-carrying line layer is arranged outside the wrapping layer. A semiconductive inner shielding layer is arranged outside the current-carrying line layer. An armor layer wraps the semiconductive inner shielding layer. A shielding layer wraps the armor layer. A thermal insulation layer wraps the shielding layer. An outer sheath layer wraps the thermal insulation layer. The structure of the cable of the utility model is designed reasonably. By using the cable of the utility model, an electric spark generation probability of the cable in a mobile installation occasion and in the coal mine can be effectively reduced; an anti-pressure ability is strong; an influence of a broken stone on the cable is reduced to the minimum; and accidents of personal electric shock and gas and coal dust explosion are effectively reduced.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to withstand voltage high-temperature resistant and antistatic removal cable for a kind of colliery.
Background technology
Different operational environments has different performance index requirements to cable, highly gassy mine is more at present, the phenomenons such as permeable, rubble often occur, the accident increasing year by year caused due to electrostatic spark, existing common cable can't be simple in structure, meet the requirement of above-mentioned operational environment, exist comparatively serious potential safety hazard.
