Description
Technical field
It is especially a kind of without the flexible wide temperature band power cable of modeling the utility model relates to field of cable technology.
Background technique
As the carrier of power transmission, the application of power cable is almost ubiquitous.Applied to the electricity in building
Power cable, other than meeting basic functional requirement, it is also contemplated that the environment friendly of product, material to health innocuousness,
The convenience of mouse bite preventing performance and cable wiring manufacture.Meanwhile to fireproofing of cable, higher requirements are also raised, does not terminate in
It is fire-retardant and avoid causing to prolong combustion, also require in the case where fire occurs, cable will not because of fire destruction and lose substantially
Transmission of electricity function, to guarantee the continued power of the emergency services such as fire-fighting, communication in case of emergency.
Addition fire retardant can not prevent flame pair with the anti-flammability of reinforced plastics in insulation and sheath material
The destruction of cable.Plastics can discharge a large amount of smog and toxic gas in the case where high temperature imperfect combustion, cause to environment and
The secondary injury of health.Cable can lose the function of continued power quickly in a fire, cause the emergency services such as fire-fighting, communication without
Paralysis.Meanwhile the plastic material for insulation protection, it is easy embrittlement cracking again under low-temperature environment.
Carrying out seamless packaging protection to cable with metallic copper, there are two disadvantages: first, in order to improve the corrosion resistance of cable,
Have to outside copper plus squeeze one layer of plastics protection, but plastics will lead to harmful toxic matter in case of fire and smog emission again
Problem；Second, cable is harder, and bending property is very poor, this makes indoor construction wiring highly inconvenient to limit cable
Application.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of without the flexible wide temperature band electric power electricity of modeling
Cable can not only guarantee continued power three hours or more under 800 DEG C of environment when fire occurs, to guarantee fire-fighting, communication, peace
The emergency systems such as anti-will not paralyse at the very start in fire, so that it has time enough to implement Emergency Responding Mechanism, simultaneously also
It will not ignite combustion-supporting, harmful toxic matter and smog will not be discharged, cause secondary injury to environment and health.
The purpose of this utility model is achieved through the following technical solutions: it is a kind of without the flexible wide temperature band power cable of modeling,
Including flexible conductor, mineral insulation layer and screw thread armor, the mineral insulation layer is coated on the outside of flexible conductor, the mine
The outside of substance insulation layer is packaged by screw thread armor, and the screw thread armor is made of stainless steel material.
Preferably, intermediate protective layer is additionally provided between the flexible conductor and mineral insulation layer.
Preferably, the flexible conductor is twisted by multiply copper core.
Preferably, the diameter of the copper core is not more than 0.4mm.
Preferably, the mineral insulation layer is made of inorganic mineral material.
Preferably, the inorganic mineral material is magnesia.
Preferably, the intermediate protective layer is made of inorganic fibers.
Preferably, the inorganic fibers are asbestos.
Preferably, the intermediate protective layer with a thickness of 0.5~1mm.
The utility model has the advantage that
1, in the utility model without modeling cable be real fireproof cable, can not only fire occur when guarantee 800
Continued power three hours or more under DEG C environment, with guarantee the emergency systems such as fire-fighting, communication, security protection will not fire at the very start
Paralysis, so that it has time enough to implement Emergency Responding Mechanism, while it is combustion-supporting also to ignite, and will not discharge harmful toxic matter
And smog, secondary injury is caused to environment and health.
2, it can be used for indoor application by stainless steel screw thread armouring in the utility model, can thoroughly prevent the nozzles tooth such as mouse
Destruction of the class animal to cable.
3, cable flexibility is good, bending radius and bending stress are smaller, facilitates construction.
4, plastics are not used without modeling cable, so the low temperature brittleness problem of Cracking of plastics is not present, therefore not by ultralow
The limitation of warm environment.
5, cable corrosion resistance is improved, destruction of the nozzles tooth class animal such as mouse to cable is avoided.The ring of the adaptation of cable
Border temperature band expands to -100 DEG C~800 DEG C to both sides, while strengthening the high temperature resistant and resistance to low temperature of cable, essentially without
Worry temperature to the destruction problem of cable again.
