Description
Technical field
The utility model is related to cable Anti-Jamming Technique field, is specially a kind of anti-interference many shaft cables.
Background technology
At present, in cable industry fireproof control cable generally using fire-resistant isinglass belt is wrapped plus insulation by the way of, but mica
With wrapped class fire-resisting cable during wrapped or bending, mica sheet easily comes off, it is impossible to by spray, vibratory test, and
Mica tape species is again more now, fine or not uneven, less stable, it is difficult to ensure that the fire resistant quality of cable.Secondly, commonly
Insulation used in fireproof control cable and sheath material mostly all containing halogen or do not reach the environmental protection of European Union ROHS instructions will
Ask, furthermore, the wrapped production of small bore fireproof control cable is restricted, and fire resistance quality can not more be protected, and should
The poor anti jamming capability of class cable.
Cable to transmit electric (magnetic) can, information and the wire product for realizing electromagnetic energy conversion, the cable of broad sense is also referred to as
For cable, the cable of narrow sense refers to insulated cable, and it may be defined as:The aggregate being made up of following part；One or more is exhausted
Edge core, and the clad that each of which may have, total protective layer and outer jacket, cable can also have additional without insulating
Conductor.To transmit electric (magnetic) energy, information and the wire product for realizing electromagnetic energy conversion.
The electromagnetic wave of radiation and the leakage of cable not only other electronic equipment normal works of severe jamming, cause functions of the equipments
Disorderly, error of transmission.Therefore the electromagnetic interference (EMI) of reduction cable has been the problem of must take into consideration.
Utility model content
The purpose of this utility model is that providing a kind of specified current capacity of cable improves, and current capacity is big, saves raw material,
Reduce cost, the aging speed for slowing down cable slowly, extend the service life of cable, and the energy-conserving and environment-protective of this cable, structure letter
It is single, make simple, a kind of low anti-interference many shaft cables of manufacturing cost, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of anti-interference many shaft cables, including cable
Line body, the cable body is provided with main cables, and the exterior circumferential of the main cables is provided with secondary cable, the secondary wire
The outside of cable is provided with common insulation sheath, and the outside of the common insulation sheath is provided with metallic shield net, the metallic shield net
Outside be provided with anticorrosive rubber layer, the gap between the main cables, secondary cable, common insulation sheath is filled out provided with fire prevention
Agent is filled, fire prevention filler uses glass fibre.
It is preferred that, the outside of the main cables is provided with asbestos layer.
