Embodiment Construction

[0014] Such as figure 1 As shown, the copper-clad aluminum alloy fireproof wire and cable of the present invention is composed of an insulating layer of fireproof mica tape 2 coated with a copper-clad aluminum conductive core wire 1, and an additional cross-linked insulating fireproof sheath 3. The conductive core wire shown in the figure 1 is composed of copper 4 coated aluminum core wire 5.

[0015] The fire-proof mica tape 2 and the fire-proof sheath 3 of the insulating layer are made by mixing nano-modified polyolefin polymer, nano-fireproof agent, nano-smoke suppressant and filler. As a preference and improvement, a graphite dielectric layer is also provided between the aluminum core wire layer and the copper layer. The graphite dielectric layer is set, which has strong oxidation resistance and improves electrical conductivity. In order to facilitate the recycling of raw materials and reduce costs, the copper is twisted from at least one pure copper wire, and the alumin...

Abstract

The invention relates to a novel environmental energy-saving fire-proofing cooper-aluminum alloy electric cable and a manufacturing method thereof. In the case of a fire, the electric wire is prone to burning to cause short circuit and flame; besides, the conventional electric wire is high in cost. The environmental energy-saving fire-proofing cooper-aluminum alloy electric cable is composed of an insulation layer (2) and a conductive core wire (1) in a coating manner and characterized in that the conductive core wire (1) is composed of the copper material and the aluminum material in the coating manner, the insulation layer (2) is a fireproofing mica tape, and a fireproofing sheath is arranged outside the insulation layer (2). The environmental energy-saving fire-proofing cooper-aluminum alloy electric cable has the advantages that safe and reliable performance is achieved, in the accidents, smoke is less in the burning environment, fireproofing ability is excellent, noxious gas and corrosive gas never occur, accidental loss is greatly reduced, material recycling is convenient, and production cost is lowered.

Description

technical field [0001] The invention relates to a new environment-friendly and energy-saving copper-aluminum alloy wire and cable, especially the wire and cable which has greatly improved the performance of the copper-aluminum alloy and greatly reduced the cost of copper conductor wires and a manufacturing method thereof. Background technique [0002] The vigorous development of building decoration has higher and higher requirements for wires and cables. In the past few decades, fires caused by the aging of wires and cables have occurred frequently. Cause greater loss or even tragedy. At present, the price of non-ferrous metal copper remains high, and the cost of copper conductors accounts for more than 90% of the total cost of cable raw materials. In order to meet the technical specifications of cable copper conductors and greatly reduce the cost of cables, there is a broad market for copper-aluminum alloy wires and cables with fire resistance and high cost performance pro...
