Description
Technical field
The utility model is related to a kind of mineral fireproof cable, and in particular to a kind of mineral fireproof cable of anti-cutting, belongs to electricity
Cable field.
Background technology
Cable is widest equipment used in electric energy transmission, in daily life, electric energy using security be one
Requirement extremely interesting issue, therefore cable being had in various performances.Traditional mineral fireproof cable is that BTTZ is rigidly anti-
Thermoelectricity cable, using magnesia as insulation filling, while also serving as fireprotection layer, but has some shortcomings, is oxidation first
The easy moisture absorption of magnesium causes insulaion resistance to decline, next to that installing and laying difficulty, easily occurs isolating even leaky, because
This, needs to be improved in these two aspects.Fire-resistant isinglass belt has good heat-resisting quantity and flame resistance, is meeting naked light burning
When be substantially not present the volatilization of harmful vapors, after the outer wrapped fireproof mica belt of conductor, cable core has excellent fire resisting fire prevention
Performance, fire-resistant isinglass belt also have good flexibility so that cable core also has flexible nature, in addition, adding Chain Link Fence
The anti-cutting performance of cable can be improved, prevents from isolating leaky in use.
Utility model content

Can be with the problem in effectively solving background technology.
In order to solve above-mentioned technical problem, the utility model provides following technical scheme：
A kind of mineral fireproof cable of anti-cutting of the utility model offer, including copper core conductor and is coated on outside copper core conductor
Refractory insulating layer, high fire-retardance oxygen barrier layer, around being wrapped on the outside of copper core conductor, high fire-retardance oxygen barrier layer is extruded in resistance to the refractory insulating layer
Single insulated wire cores are constituted on the outside of fiery insulating barrier, how cable core is twisted into insulated wire cores, is provided with packed layer on the outside of cable core, described fill out
Fill layer to extrude on the outside of cable core, interior metal protection layer is provided with the outside of the packed layer, rubber is provided with the outside of the interior metal protection layer
Glue-line, is provided with outer metal protection layer on the outside of the rubber layer.
Used as a kind of optimal technical scheme of the present utility model, the packed layer is also filled up in the space at cable core center.
Used as a kind of optimal technical scheme of the present utility model, the interior metal protection layer and outer metal protection layer are gold
Category network structure, plays anti-cutting protective action.
The beneficial effect reached by the utility model is：A kind of mineral fireproof cable of anti-cutting, outer wrapped in copper core conductor
Refractory insulating layer so that cable has excellent fire resisting fire protecting performance and softness, the low-smoke halogen-free polyolefin material of high fire-retardance
The packed layer that the high fire-retardance oxygen barrier layer and fire-retardant mineral compound that material is made is made achieves multiple protection functions, it is ensured that cable
Fire-proof insulation, be simultaneously provided with inside and outside bimetal protective layer, prevent cable from being isolated by sharp objects, play anti-cutting protective action,
Ensure that the safe and reliable of cable.
