Description

A kind of inorganic mineral type cable

Technical field

This utility model is related to technical field of electric wires and cables, more specifically refers to a kind of inorganic mineral type cable.

Background technology

Fire-retardant, fire proofing material is the essential material of current building trade, real estate industry, for electric wire, safety Property, fire retardant performance is required can be higher.Currently used cable insulation material is PVC (plastics) or XLPE (the poly- second of crosslinking Alkene), these materials be macromolecule mixture, in fire easy firing and lose insulating properties make cable short circuit, so as to cause to build Thing power-off is built, huge loss can be caused to the life and property in building, be to solve this problem, it is necessary to which design is a kind of High fire prevention, the cable of high fire-retardance, it is ensured that when there is fire, cable does not burn, and normally can power.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of inorganic mineral type cable.

For achieving the above object, this utility model is employed the following technical solutions：A kind of inorganic mineral type cable, including electricity Cable core, fire prevention sheath, metal armor layers, described cable core include a plurality of insulated wire cores, and described insulated wire cores are by conductor And the wrapped insulating barrier composition on conductor, described insulating barrier is inorganic mineral insulating tape；On the outside of described cable core according to It is secondary to be coated with described fire prevention sheath, metal armor layers.

Wherein：Described conductor anaerobic copper conductor.

Wherein：Described cable core by two, three, four, or five bar insulation cores constitute.

Wherein：Described fire prevention sheath is A level fire resisting tubing.

This utility model beneficial effect compared with prior art is：A kind of inorganic mineral type cable, can be according to not The core number of cable is selected with demand, insulating barrier, fire prevention sheath on the conductor, metal armor layers are all the incombustible of employing Inorganic mineral material, can effectively play the effect of fire-retardant, fireproof.

Reference

The fire prevention sheath of 10 conductor 40

20 insulating barrier, 50 metal armor layers

30 insulated wire cores

Specific embodiment

In order to more fully understand technology contents of the present utility model, with reference to specific embodiment to skill of the present utility model Art scheme is further described and illustrates, but is not limited to this.

Specific embodiment as shown in Figure 1, a kind of inorganic mineral type cable of this utility model, including cable core, fire prevention Sheath 40, metal armor layers 50, cable core include a plurality of insulated wire cores 30, and insulated wire cores are by conductor 10 and wrapped on conductor Insulating barrier 20 constitute, insulating barrier 20 be inorganic mineral insulating tape；It is coated with shield in described fire prevention on the outside of cable core successively Layer 40, metal armor layers 50.

Further, conductor 10 uses oxygen-free copper as conductor, and the shape of its section according to using characteristic can be Circular, fan-shaped or arch.

In the present embodiment, cable core number is four, in other embodiment, cable can may be selected according to different demands Core number is two, three or five.

Wherein, sheath 10 of preventing fires is A level fire resisting tubing (950～1000 DEG C of A levels flame temperatures, persistently for the fiery time 90min) energy sintering curing is protected inside cable core not damaged by flame and mechanical external force, is just keeping cable into hard body Often work.

In sum, this utility model can select cable to lead the cross sectional shape of core according to actual needs, it is also possible to according to Different demands selects the core number of cable, and insulating barrier, fire prevention sheath on the conductor, metal armor layers are all not firing for employing The inorganic mineral material of burning, can effectively play fire prevention, fire-retardant effect.

It is above-mentioned only with embodiment further illustrating technology contents of the present utility model, be easier to understand in order to reader, But do not represent embodiment of the present utility model and be only limitted to this, it is any to extend or recreate according to the technology done by this utility model, Be defined by claims by protection of the present utility model, protection domain of the present utility model.
