Anti-flaming fire-resistant copper alloy cable

Abstract

The invention discloses a flame-retardant and fire-resistant copper alloy cable, which comprises a copper alloy conductor formed by twisting and pressing copper alloy wires, the outer wall of the copper alloy conductor is wrapped with a fire-resistant mica tape, and the outer wall of the fire-resistant mica tape is wrapped There is a copper wire layer, the outer wall of the copper wire layer is wrapped with a flame-retardant cross-linked polyethylene insulating layer, and a flame-retardant glass fiber filling layer is also filled between the copper alloy conductors, and the outer wall of the flame-retardant glass fiber filling layer Wrapped with a shielding layer, the outer wall of the shielding layer is wrapped with an outer flame retardant layer, the outer flame retardant layer includes a nano-scale magnesium hydroxide flame retardant layer, and the upper surface of the nano-scale magnesium hydroxide flame retardant layer is tightly A PVC flame retardant layer is pressure bonded, the upper surface of the PVC flame retardant layer is sprayed with a water-based paint flame retardant layer, and the outer wall of the outer flame retardant layer is also wrapped with a sheath. The flame-retardant refractory copper alloy cable has a simple structure, and the flame-retardant performance of the cable can be effectively improved by adding flame-retardant materials.

Description

technical field [0001] The invention relates to the technical field of copper alloy cables, in particular to a flame-retardant and refractory copper alloy cable. Background technique [0002] With the development of science and technology and the improvement of economic level, various cables have come out one after another. In China, copper core cables are the most well-known, and it almost occupies more than half of the cable market. Copper core cables have the characteristics of high strength and large carrying capacity, so they are widely used. At present, the cables widely used in generators, petroleum, chemical industry, metallurgy and other high-temperature places and sewage treatment industries are composed of cable cores and sheaths wrapped around the cable cores. This type of cable has poor fire resistance, and once a fire occurs It will bring huge losses to various units and families. However, most of the refractory materials of traditional fireproof copper alloy...

At present, the cables widely used in high-temperature places such as generators, petroleum, chemical industry, metallurgy, and sewage treatment industries are composed of cable cores and sheaths wrapped around the cores. This type of cable has poor fire resistance, and once a fire occurs It will bring huge losses to various units and families. However, most of the refractory materials of traditional fireproof copper alloy cables contain harmful substances. Bring huge harm, not conducive to environmental protection
