Problems solved by technology

[0002] In recent years, with the rapid development of my country's economy, fires caused by electricity have increased year by year, and fires caused by wires and cables account for a considerable proportion. Fires caused by wires and cables are usually caused by aging and damage to the outer sheath of the cable, resulting in Its insulation is reduced, resulting in a short circuit of the cable, and some are caused by the arc explosion and combustion of the cable caused by the excessive contact resistance in the cable, and the spread of the fire along the cable line increases the hazard of the fire. Therefore, a heat-resistant , flame retardant cables have become an urgent demand

Abstract

The invention discloses a heat-resisting anti-flaming insulated cable which comprises an insulating layer, a shielding layer and a conductor. The insulating layer is made of anti-flaming polyvinyl chloride insulating materials and comprises, by weight, 40-50% of polyvinyl chloride, 10-20% of plasticizer, 35-45% of fire retardant, 0.5-1.5% of antioxygen and 0.4-1% of stabilizer. The shielding layer is made of crosslinked polyethylene, and the conductor is made of oxygen-free copper with the copper content lager than 99.95%. In this way, the heat-resisting anti-flaming insulated cable has good fire resistance and heat resistance, and meets the demand of markets for high performance of insulated cables.

Description

technical field [0001] The invention relates to the field of insulating materials, in particular to a heat-resistant and flame-retardant insulated cable. Background technique [0002] In recent years, with the rapid development of my country's economy, fires caused by electricity have increased year by year, and fires caused by wires and cables account for a considerable proportion. Fires caused by wires and cables are usually caused by aging and damage to the outer sheath of the cable, resulting in Its insulation is reduced, resulting in a short circuit of the cable, and some are caused by the arc explosion and combustion of the cable caused by the excessive contact resistance in the cable, and the spread of the fire along the cable line increases the hazard of the fire. Therefore, a heat-resistant , Flame-retardant cables have become an urgent need. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a heat-resistant and f...
