Description
Technical field
Power cable field is the utility model is related to, specifically a kind of environment-friendlymedium-voltage medium-voltage fireproof cable.
Background technology
At present, domestic skyscraper, oil platform, mine, metallurgy, ship, power station, subway, airport, station, tunnel
Deng the high occasion of fire protection requirement, halogen material is used in used cable insulation, restrictive coating mostly.Once generation is fiery
Calamity, substantial amounts of dense smoke can be not only produced, and the very strong hydrogen halide of the corrosivity with " secondary disaster " can be produced, not only
Equipment and pollution environment are easily damaged, or even jeopardizes the life of people.Even with the fire proofing of low smoke, zero halogen, can only also prolong
Slow fire proofing is burnt till the time of powder.If continuing to be burnt, shed powder will be become gradually, lose protection
Effect, easily makes electric wire breakdown and causes short circuit, smooth so as to have impact on the safety of communication, electric power in case of fire
It is logical.With requirement of the high speed development and World Environment Organization of World Economics to environmental protection, a kind of anxious green ring to be developed
Guarantor's type sets fire cable to meet the needs of human kind sustainable development, and this is the development trend of countries in the world cable technology.
Utility model content
The technical problem that the utility model cable solves is to provide a kind of green, high mechanical strength, contains a small amount of height
Imitate cross-linked material, flexible, light weight, the environment-friendlymedium-voltage medium-voltage fireproof cable of fire resistance period length.
A kind of environment-friendlymedium-voltage medium-voltage fireproof cable described in the utility model, including cable core, described cable core is by three fire prevention
Insulated wire cores and a piece-root grafting ground wire are twisted, and environment-friendly type back-fire relief expansion module are provided with the gap of cable core, outside cable core
Wrapped ceramic fire resisting composite band, fire-resisting ceramic silicone rubber insulating barrier is externally provided with ceramic fire resisting composite band, in ceramic
Fire-resistant silicon rubber insulating barrier is externally provided with ceramic fiber cloth, and ceramic polyolefin fire resisting oversheath is externally provided with ceramic fiber cloth；
Temperature inductor is provided with ceramic polyolefin fire resisting oversheath.
Further improve, described fire-proof insulation core is externally provided with heat by aluminium alloy conductor and successively in aluminium alloy conductor
The insulation screen that insulating barrier, the heat curing-type semi-conducting material of curable type cross-linking polyethylene materials composition are formed is formed.
Further improve, described environment-friendly type back-fire relief expansion module is integral type structure.
The beneficial effects of the utility model：
1st, environment-friendly type expansible fire trapping module is a kind of novel fireproof blocking material, using nontoxic expanding material and special process
It is made, is mainly used in the electric wire, cable, the fireproof blocking of electrical equipment of the industries such as petrochemical industry, electric power, communication, metallurgy, product synthesis
All advantages of traditional organic fire prevention calking, inorganic fireproofing plugging and back-fire relief bag, toxic gas will not be produced by meeting fire, not flown
Cigarette, do not fall off, green, high mechanical strength, it is flexible containing a small amount of efficient cross-linked material, be advantageous to protect cable；
The cable quality is light, and actual measurement environment-friendly type back-fire relief expansion module dry density is 0.68t/m3, quality is far below country's mark
Standard is not more than 2.5t/m3Requirement, plugging material can be mitigated significantly to cable testing bridge and the load of building；
The cable fire time is grown, because guarantor's type back-fire relief expansion module is using special formulation material composition, heat conductive
It is excessively poor, it can prevent to ignite to penetrate, fire resistance period is risen to more than 5h, be marked more than 3h as defined in country-level fire-proof product
It is accurate；
2nd, the cable employs multi-layer ceramics fire proof construction, and cable is under the vigorous combustion of flame when meeting fire, ceramics
A kind of hard ceramic layer can be quickly generated by changing fire proof construction, prevent flame from continuing inwardly burning, suitable for skyscraper, oil
The high occasion of the fire protection requirements such as platform, mine, metallurgy, ship, power station, subway, airport, station, tunnel, and be all to use ring
Protect material to form, a large amount of toxic smogs, therefore the startup when fire occurs to every system will not be produced in combustion
The time has been fought for, the person and property safety of the people has been ensure that, reduces national loss.
3rd, the cable is additionally provided with temperature inductor, when the temperature born more than cable, can send alarm, remind people
, the generation of increase and fire preventing.
