Abstract
The invention discloses a fireproof flame-retardant cable. A cable core consists of six fireproof cable cores, one nylon cable core and six control cable cores, wherein each fireproof cable core is formed by sequentially winding and cladding a fireproof layer and a metal shielding layer on three twisted insulation cable cores, each insulation cable is formed by winding and cladding a polyethylene insulation layer on a conductor, the six control cable cores are respectively arranged among adjacent cable cores of the six fireproof cable cores, the nylon cable core is arranged in the middle of the six fireproof cable cores, and each control cable core is formed by winding and cladding a second fireproof layer outside two second insulation cable cores, and a polyurethane covering belt layer, a second fireproof layer, a sheath layer and an outer protection layer are sequentially arranged outside the cable core. The fireproof flame-retardant cable has the advantages that the excellent insulation performance can still be maintained under the high-temperature combustion condition, and the fireproof flame-retardant cable can continuously operate in high-temperature flame.
Description
technical field
The present invention relates to a kind of fire protection flame retarding cable, belong 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.
summary of the invention
The invention provides a kind of fire protection flame retarding cable, can in high-temp combustion situation, still can keep at cable good insulation property, can operation continuously in thermal-flame.
The solution of the present invention is as follows: a kind of fire protection flame retarding cable, cable core is made up of the fire-resistant core of the six roots of sensation, nylon core and six roots of sensation control core, 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 is made up of wrapped polyethylene layer on conductor; 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 is made up 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.
Cable cover(ing) of the present invention 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 present invention 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 present invention uses double-layer alloy mica tape fireprotection layer, improves fireproofing of cable performance, extends cable useful life.
brief description of the drawings
