Abstract

The invention discloses a waterproof communication cable which comprises an inner conductor, an insulating layer, an outer conductor, a packing layer and an outer sheath, wherein the outer sheath wraps the outer layer of the packing layer, the packing layer wraps the outer layer of the outer conductor, and the insulating layer is arranged between the outer conductor and the inner conductor. The waterproof communication cable is good in fire resistance, good in high temperature resistance, low in cost and high in safety.

Description

A kind of water resistant communications cable

Technical field

The present invention relates to a kind of water resistant communications cable.

Background technology

Water resistant communications 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 water resistant communications 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 inner wire, insulating barrier, outer conductor, packed layer and oversheath, and described oversheath is wrapped in the skin of packed layer; Described packed layer is wrapped in the skin of outer conductor; Insulating barrier is provided with between described outer conductor and inner wire.

As preferably, in described packed layer, be filled with helium.

As preferably, described oversheath is thermosetting oversheath.

As preferably, described insulating barrier is high-foaming silicon dioxide layer.

As preferably, described inner wire is copper conductor.

As preferably, described outer conductor is aluminium conductor.

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 water resistant communications cable, comprise inner wire 1, insulating barrier 2, outer conductor 3, packed layer 4 and oversheath 5, described oversheath 5 is wrapped in the skin of packed layer 4; Described packed layer 4 is wrapped in the skin of outer conductor 3; Insulating barrier 2 is provided with between described outer conductor 3 and inner wire 1.

It should be noted that in described packed layer 4 and be filled with helium.

It should be noted that described oversheath 5 is thermosetting oversheath.

It should be noted that described insulating barrier 2 is high-foaming silicon dioxide layer.

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

It should be noted that described outer conductor 3 is aluminium conductor.

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.
