Abstract
The invention relates to a novel fire-resistant rare earth aluminum alloy cable which comprises a conductor, double-layer mica tape is winded outside the conductor, the outer side of the double-layer mica tape is wrapped by an insulating layer, a wrapping layer is arranged outside the insulating layer, the outer side of the wrapping layer is wrapped by an oxygen barrier inner protecting sleeve, an aluminum alloy linkage armor is arranged outside the inner protecting sleeve, the outer side of the aluminum alloy linkage armor is wrapped by a double-layer glass fiber belt, the outer side of the double-layer glass fiber belt is wrapped by the oxygen barrier inner protecting sleeve, and an outer protecting sleeve is arranged outside the oxygen barrier inner protecting sleeve. The novel fire-resistant rare earth aluminum alloy cable has the advantages of being reasonable in structure design, good in sealing performance, safe to use, good in fire-retardant performance, high in mechanical strength and the like. The shortages that a copper core fire resistance cable or a steel belt armor cable is heavy in weight, poor in anti-collision capability and the like are remedied by the adoption of the aluminum alloy linkage armor, the performance of the aluminum alloy linkage armor is better than the performance of the traditional steel belt armor, and the aluminum alloy linkage armor has the advantages of being easy to bend, anti-pressure, anti-impact, high in the fire resistance level, light in weight, convenient to install, and suitable for being directly buried without pipeline laying, insect-protective and the like.
Description
Technical field
The present invention relates to cables manufacturing technical field, specifically a kind of Novel fire-resistant rare earth aluminium alloy cable.
Background technology
Cable is requisite article during people live, along with the expansion of people's scope of activities, various novel cables constantly occur, especially along with people the live high stratification of scope, deepization, densification, people also more and more pay attention to for the strick precaution of fire, and well behaved fireproof cable also becomes people's active demand.
Fire-resisting cable quality is in the market uneven; partial cables cannot reach standard-required at all; in use may there is dangerous situation; especially in the time that occurring, fire there will be fusing phenomenon at the fire-resisting cable that is conductor with aluminium core; common fire-resisting cable can produce toxic smog people's life security is constituted a serious threat in the time of experience fire; in addition; what common fire-resisting cable protective layer generally adopted is steel-tape armouring; protective capability to cable is lower, turn round draw with hot conditions under very easily damaged.
Summary of the invention
