Description
Technical field
The utility model relates to a kind of fire-fire environment protection type power cable, particularly relates to a kind of fire-fire environment protection type ferroaluminium power cable technology.
Background technology
It has often been said that floods and fires have no mercy, since the mankind find fire, fire not only accelerates the development of human civilization, also brings disaster to human civilization.Along with development that is economic and society, electricity is widely used as a kind of energy, many benefits are brought to the mankind, because power cable is distributed in building construction thing along with huge numbers of families are come in the conveying of electric energy, due to heatproof weak effect, overload operation, the power cable that the factors such as insulating barrier is aging cause catches fire and often occurs, the fire of whole building will be caused, bring about great losses to the people's lives and property, people to the performance requirement of power cable also in continuous raising, require that power cable has fire-retardant, fire prevention, the characteristics such as overload capacity is strong, traditional power cable service life time is short, overload capacity is weak, thermal diffusivity and poor fire, fire resistance property is more weak, once breaking out of fire is burnt rapidly along power cable line, ask to fire-fighting emergency and bring inconvenience, cause huge loss to the economy of the people simultaneously.
Summary of the invention
The purpose of this utility model is to overcome for the problems referred to above; a kind of fire-fire environment protection type ferroaluminium power cable is provided, Flame-retardant environment-friendlymaterial material is used for the protective layer of ferroaluminium cable, be coated with last layer fireproof paint at outermost layer; play the propagation of isolation burning things which may cause a fire disaster and spread, effective fire-retardant fireproof.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of fire-fire environment protection type ferroaluminium power cable, it is characterized in that: comprise cable core, cable core outer wrapped crosslinked with silicane polyvinyl chloride insulation layer, metal screen layer, inner restrictive coating, armour, external sheath layer and fireprotection layer, insulating barrier is as the internal layer of cable, armour and flame retardant rubber as skin, for preventing extraneous mechanical damage and chemical corrosion.
Described cable core comprises and is no less than the coiling of three strands of ferroaluminium wires and forms.
Described metal screen layer is that metal wire adopts the mode of braiding to be made, and metal screen layer plays the extraneous interference signal of shielding.
Described inner restrictive coating is thermoplastic olefin material.
Described fireprotection layer adds the compositions such as various fire-proof flame-retarded agent, plasticizer for tertiary acrylic emulsion water-based material.
The beneficial effects of the utility model are: the utility model provides a kind of fire-fire environment protection type ferroaluminium power cable, crosslinked with silicane polyvinyl chloride is adopted to be insulating barrier, flame-proofed thermoplastic polyolefin is inner restrictive coating, add and coat fireproof paint at rubber outer protection jacket layer, nonpoisonous and tasteless, pollution-free, effectively suppress, isolate flame transmission and spread, power cable is played to the effect of fireproof environmental.
Accompanying drawing explanation
Fig. 1 is power cable structure schematic diagram of the present utility model.
In figure: 1 is cable core, 2 is insulating barrier, and 3 is metal screen layer, and 4 is inner restrictive coating, and 5 is armour, and 6 is external sheath layer, and 7 is fireprotection layer.
Embodiment
In order to make the purpose of this utility model, technical scheme and creation characteristic clearly understand, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of fire-fire environment protection type ferroaluminium power cable, comprise cable core 1, cable core outer wrapped crosslinked with silicane polyvinyl chloride insulation layer 2, metal screen layer 3, inner restrictive coating 4, armour 5, external sheath layer 6 and fireprotection layer 7, insulating barrier 2 as the internal layer of cable, armour 5 and flame retardant rubber as skin, for preventing extraneous mechanical damage and chemical corrosion.
Cable core 1 comprises and is no less than the coiling of three strands of ferroaluminium wires and forms, this ferroaluminium has mixed a small amount of rare earth element, by the process of a lot of chemical technology, there is good conductivity, extension shrinkage, mechanical resistant damage, anti-oxidant, anticorrosive, much lower in price compared with copper resource, the application of this alloy and popularization, saved valuable copper resource.The outer wrapped insulating barrier 2 of cable core 1 adopts crosslinked with silicane pvc material, good insulating, and compare peroxide crosslinking cross-linking radiation manufacturing process and be easy to operation control, cost is low, good flame resistance; Be metal screen layer 3 outside insulating barrier 2, the mode that metal screen layer 3 adopts metal wire to weave is made, and metal screen layer 3 plays the extraneous interference signal of shielding, and protection cable core 1 is not subject to extraneous interference when transmission of information.The advantages such as inner restrictive coating 4 is flame-proofed thermoplastic polyolefine material, adds fire retardant in polyolefin manufacturing process, and other auxiliary agents such as antioxidant form through mixing plasticizing, have stronger mechanical performance, anti-aging, high temperature resistant are widely used in power cable.
In order to the mechanical protection such as tensile strength, compression strength strengthening power cable increases the service life; armour 5 is steel-tape armouring; armoring material conventional at present has steel band, steel wire, aluminium strip, aluminum pipe etc.; what wherein steel-tape armouring, wire armoring were applied is more extensive; it has high permeability; good Magnetic Shielding Effectiveness, may be used for anti-glitch, and can make armoured cable directly buried installation and avoid poling.Be external sheath layer 6 outside armour 5 be elastomeric material, this rubber has good elasticity, insulating properties, nontoxicly there is no peculiar smell, and it is waterproof, in order to safer guarantee fireproofing of cable performance, be coated with last layer fireprotection layer 7 at external sheath layer 6, this fireprotection layer 7 adds the compositions such as various fire-proof flame-retarded agent, plasticizer for tertiary acrylic emulsion water-based material, coating layer thickness is generally 0.5-1mm, about consumption 1.5kg/m
2the spongy foam thermal insulation layer of even compact can be generated very soon when running into fire, effectively can suppress, intercept flame transmission and spread, the features such as this coating is pollution-free, nonpoisonous and tasteless, coating is thin, strong adhesion, pliability are good, and there is good insulation, anti-corrosion function.
