Abstract

Disclosed in the utility model is a fireproof flame-retardant cable. A cable core is composed of six fireproof wire cores, a nylon wire core and six control wire cores. Three insulted wire cores are twisted and then are successively wrapped by a fireproof layer and a metal shielding layer to form one fireproof wire core; and the insulted wire cores are formed by wrapping conductors with polyethylene insulation layers. The six control wire cores are respectively arranged among the six fireproof wire cores. The nylon wire core is arranged in the middle of the six fireproof wire cores. Each of the control wire cores is formed by wrapping two insulated wire cores II with fireproof layers II. Besides, a polyurethane wrap layer, a fireproof layer II, a sheath layer and an outer protection layer are successively arranged outside the cable core. Under the circumstances of high-temperature burning, the cable can maintain the excellent insulation performance, so that the cable can be used in the high-temperature flame.

Description

A kind of fire protection flame retarding cable
technical field
The utility model relates to a kind of fire protection flame retarding cable, belongs to technical field of electric wires and cables.
background technology
Along with socioeconomic development, electric wire consumption increases rapidly, electrical fire accident also occurs again and again, people are from the heaviness lesson of electrical fire accident, recognize gradually at some important places, as electric equipments in the circuits such as naval vessel, production platform, petroleum chemical enterprise, large-scale power station, large-scale command and control center and skyscraper, underground structure, tunnel, subway, under fire condition, keeping in certain hour is very important in stable running status.
utility model content
The utility model provides a kind of fire protection flame retarding cable, can in high-temp combustion situation, still can keep good insulation property at cable, can operation continuously in thermal-flame.
Scheme of the present utility model is as follows: a kind of fire protection flame retarding cable, cable core is controlled core by the fire-resistant core of the six roots of sensation, nylon core and the six roots of sensation and is formed, after described fire-resistant core is stranded by three insulated wire cores, wrapped fireprotection layer, metal screen layer form successively, and described insulated wire cores consists of wrapped polyethylene layer on conductor; The described six roots of sensation control core be separately positioned on the fire-resistant core of the six roots of sensation adjacent between, described nylon core is arranged on the fire-resistant core of six roots of sensation middle part; Described control core consists of the outer wrapped fireprotection layer II of two insulated wire cores II; Described cable core is disposed with polyurethane belting layer, fireprotection layer II, restrictive coating and outer jacket outward.
Further, described fireprotection layer, fireprotection layer II form by secondary mica tape.
Further, described restrictive coating adopts low smoke, zero halogen polyolefin material to extrude moulding.
Further, described outer jacket adopts thermoplasticity fire prevention polyolefin to extrude moulding.
The utility model cable cover(ing) adopts low smoke, zero halogen polyolefin jacket, has well the features such as fire-retardant, high mechanical properties due to low smoke, zero halogen polyolefin jacket; The utility model extrudes one deck thermoplastic halogen-free fire prevention polyolefin jacket material in oversheath outside, can effectively prevent the burning of flame, improves fireproofing of cable performance.The utility model is used double-layer alloy mica tape fireprotection layer, improves fireproofing of cable performance, extends cable useful life.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of fire protection flame retarding cable, cable core is controlled core by the fire-resistant core of the six roots of sensation 5, nylon core 6 and the six roots of sensation and is formed, after described fire-resistant core is stranded by three insulated wire cores, wrapped fireprotection layer 3, metal screen layer 4 form successively, and described insulated wire cores consists of wrapped polyethylene layer 2 on conductor 1; Described six roots of sensation control line 5 cores be separately positioned on the fire-resistant core of the six roots of sensation adjacent between, described nylon core 6 is arranged on the fire-resistant core of six roots of sensation middle part; Described control core 5 consists of the outer wrapped fireprotection layer II of two insulated wire cores II; Described cable core is disposed with polyurethane belting layer 7, fireprotection layer II 8, restrictive coating 9 and outer jacket 10 outward.
Described fireprotection layer 3, fireprotection layer II form by secondary mica tape; Described restrictive coating 9 adopts low smoke, zero halogen polyolefin material to extrude moulding; Described outer jacket 10 adopts thermoplasticity fire prevention polyolefin to extrude moulding.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and revise; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
