Description
Technical field
This utility model relates to fireproof electric wire and cable field, uses split-phase to extrude metal to block water the radial waterproofing type flexible fire-proof cable of fireprotection layer particularly to a kind of.
Background technology
Skyscraper of today has become a lot of citizen's routine work, the important place of life, but skyscraper fire extinguishing but becomes an international fire-fighting difficult problem, skyscraper once catches fire after all, building can quickly be closed by dense smoke, formed " stack effect ", the flue gas of more than 800 degrees Celsius runs into any article all can make it burn, the strongest smog and the fierce burning brought thereof, and will have a strong impact on the resident's escape being confined in floor.
The equipment such as fire fighting device in common floor, elevator, illumination guide resident's escape to save oneself when being all used to fire, but big fire can cause electric wire, cable to burn, and after stand-by power supply consumes, these equipment are by a standstill;And electric wire, ignition of cable, not only can accelerate spreading of the intensity of a fire, also will discharge substantial amounts of poison, toxic smoke;If electric wire is exposed charged, in fire, the resident of escape also has Danger Electric shock risk.Series of problems not only affects resident's escape and necessary salvage operation, also can delay the rescue period that fire fighter is valuable.
According to statistics, the frequency of electrical fire and the loss that caused all belong to first of all kinds of fire.According to analysis, wherein accounted for more than half of electrical fire by what circuit caused, even if so reasonably select cable be avoid electrical fire or breaking out of fire also can the seriality powered of Reliable guarantee fire-fighting equipment, and then put out a fire as early as possible, reduce the important step of loss.
The most traditional cable (including fire-retardant, low-smoke low-halogen, low smoke and zero halogen and its corresponding fireproof cable) runs into the spray flame retardant coating of water again and easily makes moist and lose fire resistance when running into fire, and the existence of smog and harmful gas all can be had when catching fire, being burnt or transship and insulate impaired for a long time, all cannot meet fire protection requirement.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that be that a kind of good bending property, radial water-resisting and fire protecting performance are good, a kind of radial waterproofing type flexible fire-proof cable of energy-conserving and environment-protective when simultaneously manufacturing.
The utility model discloses a kind of radial waterproofing type flexible fire-proof cable, the cable core that core of preventing fires including being blocked water by one or more is stranded, it is provided with packed layer in the gap of cable core, outer around heat-resistant fireproof band of double-baging at cable core, extrude halogen-free and low-smoke flame-retardant polyolefin sheathed outside heat-resistant fireproof band;The described fire prevention core that blocks water is by conductor, around the inorganic mineral fire resistant insulation tape wrapped on conductor, and the protective metal shell being extruded in outside inorganic mineral fire resistant insulation tape blocks water fireprotection layer and be extruded in cross-linked polyolefin that protective metal shell blocks water outside fireprotection layer or low smoke and zero halogen insulated thermal insulating layer is constituted.
In this utility model, it is preferable that described conductor is pressed stranded forming by aluminium alloy molded line, and wherein molded line lay configuration presses coefficient up to more than 0.95.
In this utility model, it is preferable that described inorganic mineral fire resistant insulation tape is mica tape or Ceramic silicon rubber composite band.
In this utility model, it is preferable that the described protective metal shell fireprotection layer that blocks water is extruded through high temperature melt by aluminum or aluminum alloy bar and forms.
After using technique scheme, the method have the advantages that
1, conductor material uses aluminium alloy, and cost is compared with copper and can be reduced about 30%, can save again a large amount of copper resource simultaneously;
2, conductor uses and presses the molded line lay configuration of coefficient more than 0.95, compares circle and presses structure and can make insulation and sheath material cost savings more than 15%;
3, the outer wrapped 4-8 layer inorganic mineral fire resistant insulation tape of conductor, compares with common fireproof cable, not only increases fireproofing of cable performance, and electrical insulation properties improves more than 10 times;
4, the protective metal shell fireprotection layer that blocks water uses aluminum or aluminum alloy gold bar to extrude through high temperature melt and form, and this operation compares cost-saved more than 50% with traditional copper sheath;
5, sheath material is environmental protection low-smoke low-halogen or low smoke and zero halogen protective cover material, when breaking out of fire, cable LSZH, to human body fanout free region, and beneficially people's escape;
6, use split-phase to extrude metal to block water fireprotection layer, compared with traditional fireproof cable, have radial water-resisting effect;
7, in this utility model, cable is possible not only to reach fireproof purpose, and the spray of water can be tolerated for a long time without losing fire resistance, and all environment-friendly materials of cable material, environment and the mankind will not produce harm, and fireproof cable conductor uses aluminum alloy materials also can save substantial amounts of copper resource.
