Description
Technical field
Field of cable technology for building is the utility model is related to, especially a kind of 70 year life-span fireproof cable for building.
Background technology
The equipment such as fire fighting device, elevator, illumination in common floor are all saved oneself for guiding resident to escape during fire,
But big fire can cause electric wire, cable to burn, after stand-by power supply consumption, these equipment will be at a standstill；And electric wire, cable
Catch fire, can not only accelerate the sprawling of the intensity of a fire, will also discharge substantial amounts of poison gas, toxic smoke；If electric wire is exposed powered, escaped in fire
Resident also have Danger Electric shock risk.A series of problems not only influences resident's escape and necessary salvage operation, can also delay fire-fighting people
The valuable rescue period of member.
Traditional cable (including fire-retardant, low-smoke low-halogen, low smoke and zero halogen and its corresponding fireproof cable) is met in the market
Easily made moist to the spray flame retardant coating for running into water during fire again and lose fire resistance, and caught fire, burnt or long-term mistake
The presence of smog and pernicious gas can all be had by carrying when insulation is damaged, can not meet fire protection requirement.And cable design service life
For 20 years or so, and building service life much mismatched.
Utility model content
The shortcomings that the applicant is directed in above-mentioned existing production technology, there is provided a kind of 70 year life-span fireproof cable for building,
So that its service life is long, fire protecting performance is good, is provided simultaneously with energy-conserving and environment-protective when certain block-water performance and manufacture.
Technical scheme is as follows used by the utility model：
A kind of 70 year life-span fireproof cable for building, including the copper being twisted by molded line or circle or aluminium alloy are led
Body, first wrapped 3~6 layers of inorganic mineral refractory ceramic band, is squeezed outside inorganic mineral refractory ceramic band on copper or aluminium alloy conductor
Bag double hyer insulation, primary insulation use irradiation crosslinked polyolefin insulating material using IXPE Insulation Material, outer layer insulation；
Copper or aluminium alloy conductor, inorganic mineral refractory ceramic band, double hyer insulation form insulated wire cores；More insulated wire cores twisted synthesizing cables
Core, around high temperature resistant of double-baging using the first ceramic fire resisting fireproof silicone rubber material filling cable core space and outside cable core after stranding
Fire-retardant band；Layer of metal sheath is extruded outside heat-resistant fireproof band, one layer of second ceramic fire resisting is extruded again outside protective metal shell
Fireproof silicone rubber material, finally extrudes one layer of halogen-free and low-smoke flame-retardant polyolefin sheathed material, the aluminium alloy conductor by conductance not
Aluminium alloy monofilament less than 65%IACS is twisted；The double hyer insulation primary insulation uses 125 DEG C of IXPEs
Insulation Material, outer layer insulation uses 125 DEG C of irradiation crosslinked polyolefin insulating material, and is extruded by the way of double-layer coextrusion.
Its further technical scheme is：
Protective metal shell is by aluminium alloy or copper use extrudes or argon arc welding is welded.
The beneficial effects of the utility model are as follows：
The utility model conductor material uses aluminum alloy materials, and cost is compared with copper can reduce by 40% or so, while again may be used
Save a large amount of copper resources.
The utility model conductor uses the molded line lay configuration of tightening factor more than 0.97, and pressing structure compared to circle can make
Insulation and sheath material cost savings more than 20%.
The utility model insulation uses double-layer coextrusion structure, and product temperature resistant grade increases to 125 DEG C by original 90 DEG C,
Current-carrying capacity of cable improves 10%, and service life was increased to 70 years by original 20 years.
The utility model sheath material is the environmentally friendly low-smoke low-halogen or low smoke and zero halogen sheath material that oxygen index (OI) is not less than 35%,
During generation fire, cable LSZH, to human body fanout free region, be advantageous to people's escape.
