Abstract
The utility model discloses a high-temperature resistant and fireproof cable. The high-temperature resistant and fireproof cable comprises a plurality of conductors which are arranged in a parallel manner. Insulating layers are wrapped outside the plurality of conductors. The plurality of conductors wrapped with insulating layers are wrapped by an inner lapping layer composed of glass fiber tape lapping, a central lapping layer composed of high-temperature glass fiber cloth lapping, a fireproof layer composed of synthesis mica tape lapping, an outer lapping layer composed of glass fiber cloth lapping, and a sheath layer. A frame is arranged inside the sheath layer, and the frame is woven by a ring of silvering brass wires to be of a net shape. According to the utility model, the three high-temperature resistant and fireproof lapping layers are employed, thereby improving the high-temperature resistant and fireproof performance. In addition, the frame structure is disposed in the sheath layer, and the frame is woven by silvering brass wires to be of a net shape, so that the cable exhibits fine anti-stretch strength and shielding capability, and actual working effects are fully met for the cable.
Description
Technical field
The utility model relates to the special cable field, relates in particular to a kind of fire resistant type cable.
Background technology
Cable is in order to transmit electricity (magnetic) energy, the wire product of information and the conversion of realization electromagnetic energy.Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.
The main feature of fire safe type power cable is a cable except transferring electric power in normal working conditions, cable still can keep the normal operation of certain hour when fire burns, be applicable to that generally skyscraper, oil field, power station, power plant, mine, chemical industry, mine, subway etc. require the higher high occasion of fire prevention condition, also be emergency power supply, fire pump, elevator communication signal system answer the power backup cable; High temperature resistant fire-resisting cable refractory ability; (be not less than 3h) within a certain period of time and be not short-circuited and open circuit fault under the direct combustion case of flame standing, guaranteeing to continue power supply to keep illumination and transmission signals; the protection personnel have the time enough safe escape, and be beneficial to the fire extinguishing and reduce the loss.
Traditional fire resistance cable is under some hot environment, and as on steel plant's conticaster and the opening, in the heat-treatment furnace etc., actual serviceability can not satisfy the real work needs fully.The utility model is simple and compact for structure, adopt three layers of lapping layer, lapping layer adopts kinds of materials respectively, help the raising of fire resistant performance, simultaneously be provided with skeleton structure in the restrictive coating class, skeleton is made of the silver-gilt copper wire woven mesh, makes when cable tensile strain intensity improves, also strengthen the shield effectiveness of cable, satisfied the real work effect of cable fully.
The utility model content
At the prior art problem, the purpose of this utility model provides a kind of fire resistant type cable, and is simple and compact for structure, be applicable on steel plant's conticaster and the opening, in the heat-treatment furnace, multiple occasion usefulness such as power plant, practical effect is good.
The technical solution of the utility model is as follows:
Fire resistant type cable, comprise several conductors, described several conductor is arranged in parallel, it is characterized in that: described several conductors outside is enclosed with insulating barrier respectively, several conductors outside behind the wrap insulate layer is enclosed with the interior lapping layer of the wrapped formation of glass fibre belt, the middle lapping layer of the wrapped formation of high temperature glass cloth, the flame retardant coating of the wrapped formation of synthetic mica tape, outer lapping layer, the restrictive coating of the wrapped formation of glass cloth successively, is provided with a circle silver-gilt copper wire in the described restrictive coating and weaves webbed skeleton.
Described fire resistant type cable is characterized in that: described insulating barrier adopts poly-tetrafluoro wrapped or glass braiding or F46 injection moulding or the wrapped formation of synthetic mica tape.
Described fire resistant type cable is characterized in that: described several conductors are respectively several copper wires or the stranded bunchy of nickel wire constitutes 1.5-35mm
2, the nominal area of section scope 1.5-35mm of described several conductors
