Problems solved by technology

[0007] Due to the low electrical conductivity, low yield strength, large creep deformation and relatively small elongation of hard pure aluminum wire materials for electrical purposes, when used for power transmission, large creep will occur due to long-term operation or current overload. deformation, resulting in loose joints, increased contact resistance, and safety issues

Embodiment Construction

[0023] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, this embodiment includes a cable core, and the cable core is made by twisting several wire cores, and the wire core includes an aluminum alloy conductor 1. Preferably, the conductor 1 uses an aluminum alloy material instead of a copper conductor cable, which solves the problem of Electrically pure aluminum conductors are prone to oxidation, poor creep resistance, etc., and the material cost is low, and the economic performance is excellent; at the same time, conductor 1 adopts a stranded conductor structure with a high conductor compression coefficient, which can reduce the conductor diameter by 5%. Save more than 10% of raw material consumption in each process; aluminum alloy conductor 1 is extruded with ceramic low-smoke halogen-free polyolefin refractory insulating layer 2, which can effectively avoid t...

Abstract

The invention relates to a novel fireproof cable which comprises a cable core. The cable core is made by twisting a plurality of conductors; each conductor comprises an aluminium alloy conductor; a ceramic low-smoke zero-halogen polyolefin fire-retardant insulating layer is extruded outside each aluminium alloy conductor; a gap of the cable core adopts a zero-halogen low-smoke fire-retardant filling layer; and a ceramic fire-retardant fireproof silicon gel composite tape, a metal fireproof layer and a ceramic low-smoke zero-halogen polyolefin fire-retardant outer protection layer are sequentially lapped outside the cable core. The novel fireproof cable is reasonable in structure and convenient to manufacture, has a good energy-saving effect, excellent fireproof performance, shock resistance and spraying resistance and is environmental-friendly.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a fire-resistant cable produced with a new structure. Background technique [0002] Today's high-rise buildings have become an important place for many citizens' daily work and life. However, fire fighting in high-rise buildings has become an international fire protection problem. After all, once a high-rise building catches fire, the building will be quickly closed by thick smoke, forming a "chimney effect". 800 Smoke above 100°C will burn anything it encounters. At the same time, the dense smoke and the violent combustion it brings will seriously affect the escape of residents trapped on the floor. [0003] The fire-fighting facilities, elevators, lighting and other equipment in ordinary floors are used to guide residents to escape and save themselves in case of fire, but the fire will cause the wires and cables to burn, and after the backup power supply is consumed, these devic...
