Abstract

The invention discloses a computer two-core cable. The computer two-core cable comprises conductors, a conductor shielding layer, an insulating layer, an insulating shielding layer, a steel tape shielding layer, a wrapping taped layer and an outer sheath, wherein the outer sheath wraps the outer layer of the wrapping taped layer; the wrapping taped layer wraps the outer layer of the steel tape shielding layer; the steel tape shielding layer wraps the outer layer of the insulating shielding layer; the insulating shielding layer wraps the outer layer of the insulating layer; the insulating layer wraps the outer layer of the conductor shielding layer; the conductors are wrapped in the conductor shielding layer. The computer two-core cable is good in flame resistance, resistant to high temperature, low in cost and high in safety.

Description

A kind of computer twin core cable

Technical field

The present invention relates to a kind of computer twin core cable.

Background technology

Computer twin 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 computer twin 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, conductor shield, insulating barrier, insulation screen, steel band screen, twining package tape lapping layer and oversheath, and described oversheath is wrapped in the skin of twining package tape lapping layer; Described twining package tape lapping layer is wrapped in the skin of steel band screen; Described steel band screen is wrapped in the skin of insulation screen, and described insulation screen is wrapped in the skin of insulating barrier, and described insulating barrier is wrapped in the skin of conductor shield, and described conductor shield internal package has conductor.

As preferably, described conductor shield is sticky plastic composite strip.

As preferably, described conductor is copper conductor.

As preferably, described insulating barrier is LSOH anti-flaming second third insulating barrier.

As preferably, to be that glass fiber is wrapped form described twining package tape lapping layer.

As preferably, described oversheath is thermosetting oversheath.

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 computer twin core cable, comprise conductor 1, conductor shield 2, insulating barrier 3, insulation screen 4, steel band screen 5, twining package tape lapping layer 6 and oversheath 7, described oversheath 7 is wrapped in the skin of twining package tape lapping layer 6; Described twining package tape lapping layer 6 is wrapped in the skin of steel band screen 5; Described steel band screen 5 is wrapped in the skin of insulation screen 4, and described insulation screen 4 is wrapped in the skin of insulating barrier 3, and described insulating barrier 3 is wrapped in the skin of conductor shield 2, and described conductor shield 2 internal package has conductor 1.

It should be noted that described conductor shield 2 is for sticky plastic composite strip.

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

It should be noted that described insulating barrier 3 is LSOH anti-flaming second third insulating barrier.

It should be noted that described twining package tape lapping layer 6 forms for glass fiber is wrapped.

It should be noted that described oversheath 7 is thermosetting oversheath.

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.
