Abstract

A rare-earth high-ferro aluminum alloy cable is provided. A wire core is formed in such a way that ceramic high-molecular composite fireproof silicone rubber wraps a rare-earth high-ferro aluminum alloy conductor. A fireproof mica tape wraps a cable core composed of the plurality of wire cores. An outer sheath layer wraps the fireproof mica tape. The rare-earth high-ferro aluminum alloy cable has good machinery performance and electrical performance, and compared with a substituted cooper conductor, the rare-earth high-ferro aluminum alloy cable has the advantages of light weight and low cost; in addition, the ceramic high-molecular composite fireproof silicone rubber forms a hard ceramic object after combustion, and the hard ceramic object is high in tensile strength, fire resistance and high-temperature resistance.

Description

Rare earth high-iron aluminium alloy cable

Technical field

The utility model belongs to cable technology field, and especially conductor adopts aluminum alloy materials composition, has the cable that keeps fire-retardant, fire-resistant, low cigarette, Halogen characteristic.

Background technology

At present, due to the superior electrical performance of copper, domestic cable generally adopts copper as conductor, but the cost ratio aluminium of copper is high a lot, many researchers are researching and developing with aluminium for copper always, to realize the more optimization utilization of resource, but mechanical performance and the corrosion resistance of common aluminium cable are poor, and rare earth high-iron aluminum alloy conductor has creep resistant, high pliable and tough, strong extension, low rebounding characteristic, under identical ampacity, the weight of rare earth high-iron aluminum alloy conductor is about the half of copper conductor, and the price of rare earth high-iron aluminum alloy conductor is about 1/3rd of copper conductor, along with the increase of the cable demand of China, adopt rare earth high-iron aluminum alloy conductor cable to replace copper conductor cable to there is reduction material cost, optimize the benefit of the utilization of resources.

The structure of general fireproof power cable is mainly extruded insulation layer outside copper conductor, and insulating barrier is outer around mica tape, and oversheath adopts low smoke and zero halogen material to reach the performance of fire-resistant, low cigarette, Halogen.Existing fireproof power cable price is high, and after burning, tensile strength is low, can not adapt to better the requirement of hot environment.

Summary of the invention

High in order to overcome existing fireproof power cable price, after burning, tensile strength is low, can not adapt to better the deficiency of hot environment, the utility model provides a kind of rare earth high-iron aluminium alloy cable, and this rare earth high-iron aluminium alloy cable cost is low, after low smoke and zero halogen and burning, tensile strength is high during burning.

The utility model solves the technical scheme that its technical problem adopts: the core of rare earth high-iron aluminium alloy cable is comprised of the outer wrapped ceramic macromolecule composite fire silicon rubber of rare earth high-iron aluminum alloy conductor, the cable core outer wrapping fire-resistant isinglass belt of several wire core composition, fire-resistant isinglass belt outer wrapping oversheath, oversheath is comprised of the cable material of polyolefin of low smoke halogen-free.

Replace the rare earth high-iron aluminum alloy conductor of copper conductor, there is creep resistant, high pliable and tough, strong extension, low rebounding characteristic, under identical ampacity, the weight of required rare earth high-iron aluminum alloy conductor is about the half of copper conductor, and the price of rare earth high-iron aluminum alloy conductor is about 1/3rd of copper conductor, cable lightweight, cost is low.

Ceramic macromolecule composite fire silicon rubber, by adding inorganic silicon powder filler, constitution controller and other promoter material to form in silicon rubber base-material, is formed hard ceramic-like object after the burning of ceramic macromolecule composite fire silicon rubber.

Beneficial effect of the present utility model is that rare earth high-iron aluminum alloy conductor has good mechanical performance and electric property, and has the advantage lightweight, cost is low compared with the copper conductor replacing; After the burning of ceramic macromolecule composite fire silicon rubber, form hard ceramic-like object, there is very strong tensile strength and fireproof high-temperature resistant characteristic, even if make cable still can bear compared with strong drop and not rupture after oversheath sustains damage.
