Abstract
The utility model discloses an insulation type heat tracing power cable comprising a sheath layer, and a ground wire, a heating wire and a loop wire arranged in the sheath layer; an insulation layer and a fireproof layer are arranged in the sheath layer; the heating wire comprises a heating conductor and a heat-collecting tube arranged outside the heating conductor; a heat storage filling layer is arranged in the heat-collecting tube; the loop wire comprises a loop conductor and an inner layer insulation pipe arranged outside the loop conductor; a shield layer is arranged outside the inner layer insulation pipe; an outer layer insulation pipe is arranged outside the shield layer; an insulation filling layer is arranged between the inner layer insulation layer and the outer layer insulation pipe; a glass fiber netting layer is arranged among the ground wire, the heating wire and the loop wire. The insulation type heat tracing power cable is simple in structure, reduces cable making cost, and the inner and outer insulation pipes are arranged outside the loop wire; the shield layer is arranged among the inner and outer insulation pipes, so usage stability and shield property of the heat tracing cable can be improved with certain level; the power cable is good in suitability and strong in practicality.
Description
Technical field
The utility model belongs to power cable technical field, is specifically related to a kind of insulated type companion thermopower cable.
Background technology
The accompanying-heat cable of prior art is mainly to rely on import, it adopts silicon rubber to do the outer wrap of line with heating function and return line mostly, although it can effectively realize companion's heat, yet because the silicon rubber cost of manufacture of prior art is higher, will certainly improve the cost of manufacture of cable, and the insulation property of the accompanying-heat cable of prior art and shielding properties poor, also can affect to a certain extent the normal use of cable, applicability is affected to a certain extent, is difficult to meet the needs in market.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, the insulated type companion thermopower cable that good insulation preformance and stability in use are strong.
The technical scheme that realizes the utility model object is a kind of insulated type companion thermopower cable, comprise restrictive coating, be arranged on the ground wire in described restrictive coating, line with heating function and return line, in described restrictive coating, be provided with insulating barrier and flame retardant coating, described line with heating function comprises heating conductor and is arranged on the thermal-collecting tube in described heating conductor outside, in described thermal-collecting tube, be provided with heat accumulation packed layer, described return line comprises return conductors, be arranged on the primary insulation pipe in described return conductors outside, in described primary insulation pipe outside, be provided with screen, in the outside of described screen, be provided with outer layer insulation pipe, between described primary insulation pipe and outer layer insulation pipe, be equipped with insulation filling layer, at described ground wire, between line with heating function and return line, be provided with glass fibre silk screen layer.
Between described flame retardant coating and institute's insulating barrier, be provided with metal composite rete and polyester film layer, described polyester film layer is arranged on the inner side of described metal composite rete.
Described insulation filling layer is polyvinyl chloride particles packed layer.
Described restrictive coating is low smoke halogen-free flame-retardant polyolefin layer.
The utlity model has positive effect: of the present utility model simple in structure, line with heating function does not need to adopt the silicon rubber of import, reduced to a certain extent the cost of manufacture of cable, and the outside of return line is also provided with inside and outside insulated tube is provided with screen between inside and outside insulated tube, stability in use and the shielding of accompanying-heat cable have been improved to a certain extent, applicability is good, practical.
