The shielded control cable is characterized in that the wire core comprises a conductor, an insulating layer, a mica tape lapped covering, and a non-alkaline glassfibre fiber braid layer sequentially in an inside-to-outside manner, wherein the conductor adopts a bunch-stranded soft copper wire; the insulating layer adopts a fluoroplastic insulating layer; the mica tape lapped covering is formed by a double-layered overlapped mica tape lapping on the outer surface of the insulating layer; and the non-alkaline glassfibre fiber braid layer is woven by single-strand non-alkaline glassfibre. The utility model has superior acidproof and alkali proof properties, and has the characteristics of non combustion, temperature resistance, and unique layer structure design and material selection. The cable has fire-proof and non combustion properties, as well as favorable anti-jamming shielding performance.

Description

The anti-interference shielding control cable of fire-proof high-temperature resistant

Technical field

The utility model relates to the anti-interference shielding control cable in control cable field, particularly fire-proof high-temperature resistant.

Background technology

Control cable is applicable to department's ac rated voltage (U0/U) 450/750V such as industry such as electric power, metallurgy, oil, chemical industry, light textile and national defence, scientific research and following electrical instrumentation, signal transmission, control and the measuring system of power distribution equipment.

During existing this type systematic is installed, at first can require cable itself can not produce the interference signal influence, and require the cable heatproof, fire prevention, fire-retardant, the structure of existing cable can't reach heatproof fully, fire prevention, requirement such as fire-retardant grade, the temperature resistant grade that present control cable is used is about 500 ℃, it is a variety of that but the existing construction of cable has, prevailing structure is formed by the cable twist that forms behind the plastic insulating layer parcel conductor by many, the cable heatproof of this structure, fire prevention and performance such as fire-retardant are all very poor, the cable of the cable inside that also has also is coated with common plastic insulating layer, its heatproof fireproof performance still can not satisfy the requirement of present system, therefore need a kind of novel control line cable structure, can effectively solve the demand of existing system control cable.

The utility model content

The utility model provides fire-proof high-temperature resistant anti-interference shielding control cable for addressing the above problem, and can reach heatproof, fire prevention, fire-retardant requirement.

The technical solution of the utility model is as follows:

The anti-interference shielding control cable of fire-proof high-temperature resistant, comprise cable core and the outer jacket that is coated on the cable core outside, cable core is made of many stranded cores, it is characterized in that: described core is followed successively by conductor from the inside to the outside, insulating barrier, the mica tape lapping layer, alkali-free glass wool fibrage layer, described conductor is bundle strand annealed copper wire, insulating barrier is the fluoroplastic insulation layer, the mica tape lapping layer is wrapped and insulating barrier outer face surface by the mica tape double-layer overlapping, alkali-free glass wool fibrage layer is that single alkali-free glass wool fibrage forms, count is more than 95%, and alkali-free glass wool fibrage layer can make cable have fire prevention, do not prolong the combustion characteristic.

Described mica tape lapping layer is all put up rate greater than 20%.

The described outer jacket that is coated on the cable core outside is followed successively by cable core belting layer, copper wire woven shield, alkali-free glass wool fibrage outer jacket from the inside to the outside.

The rate of putting up of described core belting layer is greater than 15%.

The count of described copper wire woven shield can increase the anti-interference shielding properties of control cable more than or equal to 80%.

The density of described alkali-free glass wool fibrage outer jacket has fire prevention more than or equal to 95%, does not prolong combustion, and high-temperature stability cures formation by immersing ptfe emulsion, can play better be tightly connected, the heatproof effect.

The beneficial effects of the utility model are as follows:

The utlity model has excellent acid alkalescence energy, do not prolong combustion in addition, the performance of weather, the selection of design of particular structure stratiform and material, it is fire-resistant that this cable is had, and do not prolong the characteristic of combustion, and have good anti-interference shielding properties.
