Description
Technical field
The utility model relates to the cable technology field, is specifically related to the two fire prevention of a kind of flexible silicone rubber insulation high flame retardant sheath control cable.
Background technology
Power cable is used to transmit and distribute the cable of electric energy.Be usually used in the underground electrical network in city, power station lead line, industrial and mining enterprises in-line power and cross river, the submarine transmission line in sea excessively.In power circuit, the shared proportion of cable increases just gradually.Power cable be master in electric power system in circuit in order to transmission with distribute the cable product of high-power electric energy, comprising 1-500KV and above various electric pressure, the power cable of various insulation.Along with the reach of science with the society progress, power industry to cable performance require increasingly high.According to incompletely statistics the first half of the year in 2010 fire-resistant serial cable, low-smoke non-halogen flame-retardant environment-friendly cable than the same period in former years sales volume increase by 30%.This just explains that a part of industry selecting not merely to do requirement to playing an electric conductivity aspect the cable, at each aspect of performance of cable higher requirement is arranged progressively.Therefore can progressively increase the cable demand of function admirable in all directions in Future Society.
The utility model content
The purpose of the utility model provides the two fire prevention of a kind of flexible silicone rubber insulation high flame retardant sheath power cable; This cable has advantages such as simple and reasonable, that fire resistance good, insulation is best in quality, can be widely used in the demanding numerous occasions of fire-retardant fireproof.
For reaching the foregoing invention purpose; The technical scheme that the utility model adopted is: the two fire prevention of a kind of flexible silicone rubber insulation high flame retardant sheath power cable is provided, it is characterized in that: comprise high flame retardant high-expansion fireproof restrictive coating, fire prevention lapping layer, ripple copper fire-proof and damp-proof layer, soft tin-coated copper twisted wire, potteryization silicone rubber insulation layer and fireproof filling material; Establish the soft tin-coated copper twisted wire that outer surface is enclosed with the potteryization silicone rubber insulation layer in the said fire prevention lapping layer, be filled with fireproof filling material between fire prevention lapping layer and the potteryization silicone rubber insulation layer; Said fire prevention lapping layer is provided with a ripple copper fire-proof and damp-proof layer outward, and ripple copper fire-proof and damp-proof layer is extruded with a high flame retardant high-expansion fireproof restrictive coating outward.
Further, said soft tin-coated copper twisted wire is provided with the 1-5 root and does not wait, and the soft tin-coated copper twisted wire of each root all is enclosed with a potteryization silicone rubber insulation layer outward.
Further, the cross section of said soft tin-coated copper twisted wire is circular, fan-shaped or bow-shaped structural.
In sum, the two fire prevention of the flexible silicone rubber insulation high flame retardant sheath power cable that the utility model provided has following advantage:
1, through high flame retardant expansible fireproof restrictive coating is set, when fire, can reduce the cable body temperature, prolong the insulation debatable time, or avoid insulating barrier impaired, play initial protective effect, make this cable can reach the fire-resistant requirement of A level among GA306 and the GB/T19666;
2, potteryization silicon rubber is a kind of novel refractory insulating material; When sheath was damaged, temperature rise made the insulating barrier potteryization but not carbonization under case of fire, and the ceramic body that forms is again good insulation performance layer and heat-resistant layer; Therefore this cable can continue to use behind the fire, need not to change;
3, this cable is higher than mineral insulation softness and production efficiency, can produce continuously, and solve the problem of mineral insulation humidity resistance difference, and it is best in quality to insulate.
Description of drawings
