Description
Technical field
The utility model relates to field of cable technology, particularly a kind of halide-free low-smoke fireproof cable for building.
Background technology
Cable for building all adopts common polyvinyl chloride as insulation and sheath for a long time, and the ordinary life of electric wire is about 25 years, simultaneously because polyvinyl chloride belongs to Halogen material, does not meet low-carbon environment-friendly requirement.Since entering 21 century, the developing direction of electric wire is progressively to the environmental protection future development of low-smoke non-halogen flame-retardant, its technology also reaches its maturity, and particularly in nuclear power station, also should meet 60 years designed lives for the requirement of cable, the cable of the high life of this environmental protection becomes development trend.And current domestic House Property is 70 years, use 25 year life-span and electric wire not environmentally has not met requirement instantly, this phenomenon must be broken, useful life was brought up to 70 years by 25 years by existing national standard, reach the good result of once laying, using throughout one's life, accomplish safety durable, environmental protection, for resident's safety utilization of electric power provides reliable guarantee, 70 year life-span halogen-free low-smoke flame-retardant electric wire and cable for building is the necessary choice of cable for building.
At present, national building trade is tentatively drawing up 70 year life-span halogen-free low-smoke flame-retardant electric wire and cable standard for building, and regulation electric wire is not less than 70 years useful life first, synchronous with 70 years property right house life-spans.After new standard is announced, within 70 year, long-life cable will be selected by Real Estate Corporations.
Utility model content
The purpose of this utility model is the defect being to overcome above-mentioned prior art, provides a kind of halide-free low-smoke fireproof cable for building.
The purpose of this utility model is realized by following technical proposals:
A kind of halide-free low-smoke fireproof cable for building, comprise cable core, outer jacket and be filled in filling separator between the two, described cable core is made up of insulated wire cores, described insulated wire cores is made up of conductor and insulating barrier, described insulating barrier is the two-layer composite comprising inner insulating layer and external insulation layer, by internal layer IXPE material and outer field low-smoke non-halogen flame-retardant cross-linking radiation polyolefine material is disposable is made by co-extrusion to.
As preferably, described cable core is made up of 1-5 root insulated wire cores.
As preferably, described filling separator extrudes filling by halogen-free flame retarding elastomer inserts and makes.
As preferably, described outer jacket is made up of cross-linking radiation polyolefin.
As preferably, between described filling separator and outer jacket, be also provided with armour.
The utility model has following characteristics:
1. have employed two-layer compound insulating barrier, inner layer material is IXPE, this material has high dielectric property, cladding material is low-smoke non-halogen flame-retardant cross-linking radiation polyolefin, there is good fire resistance, by disposable for this bi-material co-extrusion, both ensured that insulation had good insulation electric property, greatly improved flame-resistant insulation fire resistance again.
2. fill separator to adopt halogen-free flame retarding elastomer to fill stockline to extrude filling, ensure cable core rounding, simultaneously because this kind of material is high flame resistance, low smoke halogen-free material, have very strong fire-retardant, corrosion-resistant anti-aging characteristic, protects insulated wire cores very well.
3. outer jacket adopts cross-linking radiation polyolefin jacket material, and polyolefine material has and ensures cable low smoke and zero halogen environmental protection feature, and crosslinked thermosetting material is compared with thermoplastic, significantly promotes sheath physical and mechanical properties, adds cable useful life.
4. cable core can adjust according to client's power receiving equipment, can select the cable core that single insulated wire cores forms, or the cable core that 2-5 root insulated wire cores is stranded.
5. be improve cable physical and mechanical properties further, can consider to add armour between filling separator and outer jacket.
In sum, the utility model has the feature of compact conformation, excellent fireproof performance, environmental protection, has the useful life being not less than 70 years, meets the demand to electric wire environmental protection and fire-retardant fireproof in following housing building completely.
