Abstract
The invention discloses a medium-soft clay fire resistant cable. The medium-soft clay fire resistant cable comprises a conductor in the center of the cable. A mica tape winds and wraps the conductor, an inner conductor insulating layer is arranged outside the mica tape in an extruding mode, an insulating fireproof outer protection layer is arranged on an outermost layer of the cable in an extruding mode, and a medium-soft isotropy refractory clay layer is wrapped between the inner conductor insulating layer and the outer protection layer in a plastic mode. The medium-soft clay fire resistant cable has good high-temperature resisting performance; during the combustion, corrosivity and toxicity are low, an extremely small amount of smog is produced, and therefore the hurt to a human body and the damage to a device are reduced, timely rescue can be carried out when the flood happens, the service life of the cable is prolonged, and the accident rate is reduced.
Description
Technical field
The invention belongs to power cable field, be specifically related to a kind of semisoft clay fire-resisting cable.
Background technology
Fire-resisting cable structure and common cable are basic identical, adopt the good copper conductor (fusing point approximately 1083 degree) of fire resistance, and increase flame retardant coating at conductor between conductor and insulating barrier, are made up of multilayer Mica tape.
Under burning condition, still can maintain the normal work of this circuit a period of time at certain hour cable, this cable mainly uses at emergency power supply to user's fire-fighting equipment, floods warning device, Emergency Power and socket, the current supply circuits such as Emergency Elevator, in the time of floods, normally work, while being less than floods, ambient temperature rises, for ensureing the conveying of circuit, reduce pressure drop, fire-resisting cable can not be used as high temperature-resistant cable and use.
Summary of the invention
The object of this invention is to provide a kind of plasticity better, high temperature resistant, fire-resistant, corrosion resistance more than half mild-clay fire-resisting cable.
A kind of semisoft clay fire-resisting cable of the present invention, comprise the conductor of cable center, wrapped mica tape outside conductor, mica tape extrudes inner wire insulating barrier outward, the outer jacket that cable outermost layer extruded insulation is fire-resistant, moulds bag half soft property fire clay layer between inner wire insulating barrier and outer jacket.
Further improve, described mica tape adopts aluminum plastic composite belt longitudinal bag to form.
Beneficial effect of the present invention is:
This is invented mainly for the shortcoming of the concept of fire-retardant and fire-resisting cable, structure, characteristic and is improved, after cable cabling, add a kind of half soft property fire clay of one deck, thereby improve the corrosion-resistant performance such as smokeless of the fireproof high-temperature resistant of cable itself, the possibility of minimizing accident generation.The present invention not only has good resistant to elevated temperatures performance, and it is lower to form corrosivity and the toxicity in when burning, produces the smog of minute quantity, thereby has reduced the injury to personal equipment, while being conducive to floods occur, rescues in time.Extend the cable operating time, reduce accident rate.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of semisoft clay fire-resisting cable of the present invention, comprise the conductor 1 of cable center, at the outer wrapped mica tape 2 of conductor 1, the outer inner wire insulating barrier 3 that extrudes of mica tape 2, the outer jacket 5 that cable outermost layer extruded insulation is fire-resistant, moulds bag half soft property fire clay layer 4 between inner wire insulating barrier 3 and outer jacket 5.
Described mica tape 2 adopts aluminum plastic composite belt longitudinal bag to form.
This cable operation principle is: construct at special occasions, in the situation of flame combustion, can keep the normal operation of certain hour, keep the integrality of circuit, the acid gas amount of smoke producing when burning is few, fire-resistant and fire resistance improves, and the in the situation that of particularly following water to drench with mechanical strike in the time of burning, cable still can keep the entire run of circuit.
The invention provides a kind of semisoft clay fire-resisting cable; the above is only preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improve and also should be considered as protection scope of the present invention.
