Abstract
The utility model discloses a self-breaking type fireproof cable, comprising an outermost sheath, current wire cores arranged in the sheath and insulating layers wrapping on the outsides of the current wire cores; wherein fireproof cores are arranged between the current wire cores and the sheath. According to the self-breaking type fireproof cable of the utility model, by evenly embedding a plurality of polyvinyl chloride insulating small-cross section aluminum core fireproof wires on the outer layer of a crosslinked cable, when a cable is on fire, the fireproof wires are burned out firstly to urge a protecting device to cut off the electric power lines automatically, and the cable is not electrified any longer, thereby guaranteeing the power equipment and rescue personnel safety.
Description
Technical field
The utility model belongs to the power cable technical field, is specifically related to a kind of self-stopping type fireproof cable.
Background technology
Existing fireproof cable generally is to be employed in wrapped mica tape on the conductor wire core; Switch in short-term when keeping fire; The wrapped first productive rate of this structure is lower, and second the mica tape price is higher, and three can make other power device aggravate fire because of short circuit; Four fundamental rules are still charged because of cable, and fire-fighting by water to injure rescue personnel self.
Summary of the invention
The utility model is in order to solve the problem that prior art exists, and can cut off the novel self-stopping type fireproof cable of power circuit when a kind of breaking out of fire is provided automatically.
The technical scheme of the utility model: a kind of self-stopping type fireproof cable, comprise outermost sheath, the electric current core that is provided with in the sheath and be coated on the outer insulating barrier of electric current core is provided with the fire prevention core between said electric current core and the sheath.
Said fire prevention core is an aluminium conductor.
Said fire prevention core coats the polyvinyl chloride insulation layer outward.
Said electric current core quantity is 3-6.
Said fire prevention core quantity is 3-6.
The technique effect of the utility model: the cable of the utility model evenly distributes at outer some of the small bore aluminium core fire lines that embed polyvinyl chloride insulation of crosslinked cable; When ignition of cable; Fire line is at first blown; Impel protective device to cut off power circuit automatically, cable is no longer charged, has guaranteed power consumption equipment and rescue personnel's safety.
