Background technology
Along with the fast development of modern society, skyscraper is more and more universal, in skyscraper distribution system electrical design, and power supply reliability, engineering economy and construction convenience seem more and more important.Branch cable arises at the historic moment, and the branch joint contact resistance of branch cable is minimum, is not expanded with heat and contract with cold and the influence of slight vibration, has good shock resistance, air-tightness, water proofing property, non-maintaining, its conductor performance, insulation property, the physical and mechanical properties of material all is higher than the requirement of GB/T12706.Branch's connector is connected as a single entity the conductor of backbone cable and branch cable, and flame-retardant in addition, moistureproof processing.At present, the low smoke and zero halogen branch cable of background technology is in the high-temp combustion process, insulating barrier emits gas, this gas is poisonous halogen gas, cause the short circuit of cable after the insulation fusing, so common low smoke and zero halogen Insulation Material, oxygen barrier layered material and protective cover material can not pass through the requirement of HJXXX-20XX (draft for deliberation) " environmental labelling product specification requirement-electric wire ", cause toxic gas to leak in a large number, become the fatal killer under the hot environment.
The utility model content
The utility model purpose provides the fire-resistant branch cable of a kind of environmental-friendly halogen-free low-smoke polyolefin high flame retardant, meet the requirement of country about characteristics such as electric wire Halogen, environmental protection, realize cable environmental protection, smokeless nontoxic, flame-retardant, solve the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the fire-resistant branch cable of environmental-friendly halogen-free low-smoke polyolefin high flame retardant, comprise trunk conductor, a dried conductor, connector, flame retardant coating, insulating barrier, oxygen barrier layer, metal armouring layer, external sheath layer, a trunk conductor and a dried conductor are provided with flame retardant coating, insulating barrier, oxygen barrier layer, metal armouring layer, external sheath layer from inside to outside successively respectively, constitute a main cable and a dried cable respectively, a main cable and a dried cable link together by connector.
Be provided with the connector restrictive coating in main cable, a dried cable, connector outside.
Described trunk conductor and dried conductor are that to adopt purity be that 99.99% oxygen-free copper is made, and conductor resistance is lower than the requirement of GB/T3956, has energy-conservation, as to reduce loss performance.
Described flame retardant coating is a wrapped two-layer mica tape outside conductor, can realize the fire-resistant function of cable.
Described insulating barrier is the insulating barrier of low-smoke halogen-free polyolefin Insulation Material, guarantees that the thermal contraction value of insulation is controlled at (standard is≤4) below 2, prolongs the useful life of cable.
Described oxygen barrier layer is the oxygen barrier layer of nontoxic low smoke and zero halogen, and the requirement that this material can pass through HJXXX-20XX (draft for deliberation) " environmental labelling product specification requirement-electric wire " can realize the requirement of high-rise building to the cable environment-protecting asepsis.
Described metal armouring layer is the wrapped metal armouring layer that forms in the double-deck gap of galvanized steel strip that adopts 0.5mm thickness, guarantees that cable is not bitten by mouse, thereby guarantees the useful life of cable.
Described external sheath layer is the external sheath layer that hangs down nontoxic low smoke and zero halogen material, and the requirement that this material can pass through HJXXX-20XX (draft for deliberation) " environmental labelling product specification requirement-electric wire " can realize the requirement of high-rise building to the cable environment-protecting asepsis.
The beneficial effects of the utility model: the utility model is because cable insulation adopts low-smoke halogen-free polyolefin Insulation Material, oxygen barrier layer to adopt low smoke and zero halogen oxygen barrier layered material, sheath to adopt low-smoke and halogen-free flame retardant polyolefin jacket material, can realize the requirement that fire-retardant category-A is fire-resistant, and can pass through the requirement of HJXXX-20XX (draft for deliberation) " environmental labelling product specification requirement " by adopting about characteristics such as electric wire Halogen, environmental protection through nontoxic low smoke and zero halogen Insulation Material, oxygen barrier layered material, protective cover material, real realization cable environmental protection, the smokelessly characteristic requirement of nontoxic, flame-retardant.
