Abstract
The invention relates to a special-grade fireproof highly-anti-flaming nanometer power cable which comprises a plurality of cable cores and an outer sheath. Each cable core is formed by a copper conductor, double-layer fireproof mica tape and a fireproof nanometer insulating layer, wherein the double-layer fireproof mica tape and the fireproof nanometer insulating layer are sequentially wrapped outside the copper conductor, anti-flaming filling ropes are filled outside the cable cores, glass fiber tape is wrapped, and the fireproof nanometer outer sheath is wrapped outside the glass fiber tape. The electric-conducting and anti-flaming capabilities of the cable are improved. The cable overcomes the shortcomings existing in a traditional cable, has excellent anti-flaming performance, and has simultaneously the advantages of being high in transmitting rate, small in line loss, high in safety performance in use, free of environmental pollution and low in installing and maintenance cost and the like. The special-grade fireproof highly-anti-flaming nanometer power cable is increasingly applied to various fields and occasions such as subways, nuclear power stations, markets, hospitals and intelligent buildings where the requirements for safety reliability of electrical equipment are high, and has good market prospects.
Description
technical field [0001] The invention relates to a power cable technology, in particular to a nano-tech fireproof and high flame-retardant power cable. Background technique [0002] With the rapid development of my country's industry, the scope and amount of plastic insulated cables in the industry are increasing. Ordinary plastic insulated cables have poor flame retardancy. After adding flame retardants, the electrical insulation is reduced, and a large amount of toxic and harmful smoke is produced when burning. , It is extremely harmful to the environment, equipment and personnel's life. The nano-fireproof material can be overloaded by 2.5 times under the rated voltage and can still play the role of insulation; the long-term working temperature range is: -40°C to 1200°C, as usual insulation; Short circuit, no electric fire; low smoke, non-toxic, halogen-free, flame retardant; low cost, good performance; suitable for insulating layers of various wires and cables. In view of...
