Porcelainized nano-composite insulating material aluminum alloy fireproof cable

Abstract

The invention discloses a porcelainized nano-composite insulating material aluminum alloy fireproof cable. The porcelainized nano-composite insulating material aluminum alloy fireproof cable comprises a conductive core, a fire-resistant insulating layer, a wrapping layer, an armored layer, and a sheath layer, the fire-resistant insulating layer is covered on outside of the conductive core, the wrapping layer is covered on the outside of the fire-resistant insulating layer, the armored layer is covered on the outside of the wrapping layer, and the sheath layer is covered on the outside of the armored layer; the conductive core is made of rare earth high-iron aluminum alloy material, and the fire-resistant insulating layer is made of porcelainized nano-composite fire-resistant silicon rubber insulating material, and the conductive core can be one or more. The porcelainized nano-composite fire-resistant silicon rubber insulating material has good character of being good in elastic of the normal silicon rubber, and is non-toxic, odorless, high and low temperature resistant, ozone ageing resistant, weather ageing resistant, and excellent in electric insulation performance, and has good processing property of the normal high temperature silicon rubber, and is capable of maintaining the soft cable state at the temperature of -40 DEG C to 200 DEG C.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a fireproof cable made of aluminum alloy with ceramic nanocomposite insulating material. Background technique [0002] Power cables are extremely dangerous materials that transmit flames and expand the scope of fires. When the cables burn, they can produce a lot of dense smoke, which makes rescue work difficult, and the dense smoke contains a lot of halogen gas, which aggravates the hazards to rescuers. According to the analysis of the causes of 1,464 people killed in 393 building fires in the United States, 1,062 people died of poisoning and lack of oxygen, accounting for 75.5% of the total number of deaths, and 359 people were directly burned to death by flames, accounting for only 24.4%. . A large amount of smoke and poisonous gas will knock people down, and they will be burned to death if they cannot leave the scene, which also makes it difficult to fight f...
