Abstract
The utility model discloses a ratproof, fireproof and wear-resistant type power cable, comprising a plurality of conductors, wherein aluminium foil Mylar and insulating layers are wrapped outside the plurality of conductors respectively; the plurality of conductors wrapped with the insulating layers are mutually twisted into a bundle to compose a cable core; a tape-wrapping layer is lapped outside the cable core; the tape-wrapping layer is composed of an inner layer which is formed by lapping polyurethane film tapes in an overlapping manner, and an outer layer formed by lapping synthetic mica tapes in an overlapping manner; a filling layer formed by filling high-temperature-resistant glass wires is arranged between the tape-wrapping layer and the cable core; a tensile core formed by twisting three steel wires into a bundle is arranged in the filling layer; a shielding layer, a waterproof layer and a sheath layer are sequentially wrapped outside the tape-wrapping layer; and wear-resistant particles and ratproof repellent particles are uniformly distributed in the sheath layer. According to the utility model, the ratproof repellent particles and the wear-resistant particles are arranged in the sheath layer of the cable, thus decreasing the probability of the damage on the outer layer of the cable caused by rats; simultaneously, the fire-resistant strength and the wear-resistant strength of the cable are improved, thus greatly prolonging the service life of the cable.
Description
Technical field:
The utility model relates to power cable, relates in particular to a kind of mouse bite preventing fire prevention wear-resisting type power cable.
Background technology:
It is one of three big main harm of harm cable that damaged by rats is destroyed, and consequent accident all causes enormous economic loss.Mouse baits can cause the cable water inlet or advance tide, just might cause accidents such as power failure, communicating interrupt, serious short circuit, fire, brings immeasurable loss.Foreign statistic, in the fire of city unknown cause 4 since mouse bite cable broken and cause.The loss that field army cause owing to the destruction of holding wire, connection, cable more can't be calculated with money.Mouse baits cable and has repeatability.For this reason, exploitation has good mouse bite preventing function, effectiveness is lasting, processing is stable, will have extremely important meaning to person poultry safety, novel protection against rodents technology free from environmental pollution, that price is suitable, and the ten minutes that seems is urgent.
How to improve the fire resistance and the anti-wear performance of cable simultaneously be the current problem that presses for solution to mouse bite preventing.
The utility model content:
The purpose of the utility model provides a kind of mouse bite preventing fire prevention wear-resisting type power cable, can effectively reduce the skin that damaged by rats is destroyed cable, improves fire-resistant, scuff resistance simultaneously, has prolonged the useful life of cable.：
The technical scheme of the utility model is following:
Mouse bite preventing fire prevention wear-resisting type power cable; Comprise several conductors, it is characterized in that: described several conductors are enclosed with respectively outward that the aluminium foil wheat is drawn, insulating barrier, and the mutual stranded bunchy of several conductors of wrap insulate layer constitutes cable core; Cable core is surrounded with belting layer outward; Described belting layer is made up of overlapping wrapped internal layer that constitutes of polyurethane film band and the overlapping wrapped skin that constitutes of synthetic mica tape, and wherein the wrapped rate of putting up of internal layer is not less than 25%, and the outer field wrapped rate of putting up is not less than 30%; Be provided with the pyroceram silk between belting layer and the cable core and fill the formation packed layer; Be provided with the tensile core that three stranded bunchys of steel wire constitute in the packed layer, belting layer is enclosed with screen, watertight composition, restrictive coating outward successively, is evenly distributed with the particle of abrasion resistant particles and protection against rodents repellent agent in the restrictive coating.
Described mouse bite preventing fire prevention wear-resisting type power cable, it is characterized in that: described screen adopts the zinc-coated wire braiding to constitute, and braiding rate ratio is less than 85%.
The utility model has the advantages that:
The utility model is provided with the particle and the abrasion resistant particles of protection against rodents repellent agent in the restrictive coating of cable, reduced cable by the probability of damaged by rats destruction cable outer layer, has improved the fire-resistant and scuff resistance of cable simultaneously, has prolonged the useful life of cable greatly.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1:
Mouse bite preventing fire prevention wear-resisting type power cable; Comprise several conductors 1, several conductors 1 are outer to be enclosed with respectively that the aluminium foil wheat draws 2, insulating barrier 3, and several conductors 1 mutual stranded bunchy of wrap insulate layer 3 constitutes cable core; Cable core is surrounded with belting layer 4 outward; Belting layer 4 is made up of overlapping wrapped internal layer 4-1 that constitutes of polyurethane film band and the overlapping wrapped outer 4-2 that constitutes of synthetic mica tape, and wherein the wrapped rate of putting up of internal layer 4-1 is not less than 25%, and the wrapped rate of putting up of outer 4-2 is not less than 30%; Be provided with the pyroceram silk between belting layer 4 and the cable core and fill formation packed layer 5; Be provided with the tensile core 6 that three stranded bunchys of steel wire constitute in the packed layer 5, be enclosed with screen 7, watertight composition 8, restrictive coating 9 successively outside the belting layer 4, be evenly distributed with the particle 11 of abrasion resistant particles 10 and protection against rodents repellent agent in the restrictive coating 9.
