Abstract

The invention discloses a steel wire armored high-fidelity cable. The steel wire armored high-fidelity cable comprises conductors, insulating layers, a packing layer, a wrapping taped layer, a lining layer, a steel wire armored layer and an outer sheath; each insulating layer wraps the corresponding conductor; the packing layer wraps the outer layers of the insulating layers; the wrapping taped layer wraps the packing layer; the wrapping taped layer is sequentially wrapped in the lining layer, the wrapping taped layer and the outer sheath. The steel wire armored high-fidelity cable is good in flame resistance, resistant to high temperature, low in cost and high in safety.

Description

A kind of wire armoring high-fidelity cable

Technical field

The present invention relates to a kind of wire armoring high-fidelity cable.

Background technology

Wire armoring high-fidelity cable is widely used in the place relevant with fire safety and fire-extinguishing and lifesaving such as skyscraper, underground railway, undergrond street, large-scale power station and important industrial and mining enterprises, such as, fire-fighting equipment and promptly to supply line and the control circuit of the emergency services such as leading lights., although the normal power supply that still can maintain a period of time after catching fire, there is price, complex process, problem that difficulty of construction is large in existing mineral insulated cable

Summary of the invention

For the deficiency that prior art exists, the present invention seeks to be to provide a kind of wire armoring high-fidelity cable, fire resistance is good, high temperature resistance, and cost is low, and fail safe is high.

To achieve these goals, the present invention realizes by the following technical solutions: it comprises conductor, insulating barrier, packed layer, twining package tape lapping layer, inner covering, steel wire armor layer and oversheath, and described insulating barrier is wrapped in outside conductor; Described packed layer is wrapped in the skin of insulating barrier; Described twining package tape lapping layer is wrapped in outside packed layer, and described twining package tape lapping layer is enclosed with inner covering, steel wire armor layer and oversheath outward successively.

As preferably, described conductor is copper or aluminium conductor.

As preferably, described insulating barrier is PVC insulating barrier.

As preferably, described packed layer is for receiving the heat insulation soft felt of base.

As preferably, described oversheath is wire armoring sheath.

As preferably, described inner covering is soft evacuated panel.

Fire resistance of the present invention is good, high temperature resistance, and cost is low, and fail safe is high.

Accompanying drawing explanation

The present invention is described in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is structural representation of the present invention;

Embodiment

The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.

With reference to Fig. 1, this embodiment is by the following technical solutions: a kind of wire armoring high-fidelity cable, comprise conductor 1, insulating barrier 2, packed layer 3, twining package tape lapping layer 4, inner covering 5, steel wire armor layer 6 and oversheath 7, described insulating barrier 2 is wrapped in outside conductor 1; Described packed layer 3 is wrapped in the skin of insulating barrier 2; Described twining package tape lapping layer 4 is wrapped in outside packed layer 3, and described twining package tape lapping layer 4 is outer is enclosed with inner covering 5, steel wire armor layer 6 and oversheath 7 successively.

It should be noted that described conductor 1 is copper or aluminium conductor.

It should be noted that described insulating barrier 2 is PVC insulating barrier.

It should be noted that described packed layer 3 is for receiving the heat insulation soft felt of base.

It should be noted that described oversheath 7 is wire armoring sheath.

It should be noted that described inner covering 5 is soft evacuated panel.

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
