Abstract

The invention discloses a novel single-core cable. The novel single-core cable comprises a conductor, an insulation layer, a packing layer, a warping-tape warping layer, a lining layer, a steel tape armor layer and an outer sheath, wherein the insulation layer wraps the conductor; the packing layer wraps an outer layer of the insulation layer; the warping-tape warping layer wraps the packing layer; the lining layer, the steep tape armor layer and the outer sheath sequentially wrap the warping-tape warping layer. The novel single-core cable is high in fireproof performance, resistant to high temperature, low in cost and high in safety.

Description

A kind of novel single-core cable

Technical field

The present invention relates to a kind of novel single-core cable.

Background technology

Novel single-core 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 novel single-core 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-tape armouring 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-tape armouring layer and oversheath outward successively.

As preferably, described conductor is copper conductor.

As preferably, described insulating barrier is that multilayer Mica tape forms.

As preferably, described packed layer is glass fibre.

As preferably, described oversheath is high molecule plastic material.

As preferably, described oversheath scribbles refractory coating.

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 by the following technical solutions: a kind of novel single-core cable, comprises conductor 1, insulating barrier 2, packed layer 3, twining package tape lapping layer 4, inner covering 5, steel-tape armouring layer 6 and oversheath 7, and 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-tape armouring layer 6 and oversheath 7 successively.

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

It should be noted that described insulating barrier 2 forms for multilayer Mica tape.

It should be noted that described packed layer 3 is glass fibre.

It should be noted that described oversheath 7 is high molecule plastic material.

It should be noted that and described oversheath 7 scribbles refractory coating.

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.
