Abstract
The utility model relates to an insulating flame-retardant mobile flexible cable used for coal mine, comprising a cable core and a flame-retardant polyolefin oversheath; wherein the cable core consists of one or more than one wire core, the each wire core consists of a conductor, a crosslinking EVA conductor shielding layer, a crosslinking polyethylene insulating layer, a crosslinking EVA insulating shielding layer and a copper net shielding layer from interior to exterior, a ceramic silicone rubber composite belt is wrapped outside the cable core, fireproof mud is filled between the ceramic silicone rubber composite belt and the cable core, a plurality of aramid fiber reinforcing wire cores are uniformly wrapped outside the ceramic silicone rubber composite belt, and the flame-retardant polyolefin oversheath is wrapped outside the aramid fiber reinforcing wire cores. The insulating flame-retardant mobile flexible cable of the utility model has the beneficial effects of soft structure, convenient paving, excellent fire resistance, and high security.
Description
Technical field
The utility model is related to a kind of colliery flame-resistant insulation mobile flexible cable.
Background technology
During coal mining, the presence of biogas is frequently accompanied by coal seam, therefore have very high requirement to anti-knock properties and anti-flammability to power cable, common power cable can not be used within coal mines, and narrow space in colliery, the pernicious gas sent after cable fire is easily assembled, and can not only hinder the escape of staff in ore deposit, but also can directly endanger the life of staff in ore deposit.Although can reach good fire resistant flame retardant performance using the cable of metal armouring, cable is harder, is difficult to mat formation.
Utility model content
Technical problem to be solved in the utility model is：A kind of colliery flame-resistant insulation mobile flexible cable, structurally flexible are provided, and there is higher fire-retardant, refractory ability.
The utility model solves the technical scheme that its technical problem used：A kind of colliery flame-resistant insulation mobile flexible cable, including cable core and fire retardant polyolefin oversheath, cable core is made up of the core of one and more than one, core is made up of conductor, crosslinked EVA conductor shield, crosslinked polyetylene insulated layer, crosslinked EVA insulation screen, copper mesh screen layer from the inside to the outside, the wrapped Ceramic silicon rubber composite band outside cable core, fire-proof mud is filled between Ceramic silicon rubber composite band and cable core, uniform ring is around many aramid fiber reinforced cores outside Ceramic silicon rubber composite band, and fire retardant polyolefin oversheath is wrapped in outside aramid fiber reinforced core.
Conductor is the stranded flexible conductor of copper wire.
The beneficial effects of the utility model are：Structurally flexible, is easy to mat formation, excellent fire retarding performance, safe.
Brief description of the drawings
Fig. 1 structural representations of the present utility model；
In figure：1. fire retardant polyolefin oversheath；2. core；3. Ceramic silicon rubber composite band；4. fire-proof mud；5. aramid fiber reinforced core.
Embodiment
As shown in Figure 1, a kind of colliery flame-resistant insulation mobile flexible cable, including cable core and fire retardant polyolefin oversheath 1, described cable core is made up of the core 2 of one and more than one, core 2 is from the inside to the outside by conductor, crosslinked EVA conductor shield, crosslinked polyetylene insulated layer, crosslinked EVA insulation screen, copper mesh screen layer is constituted, the wrapped Ceramic silicon rubber composite band 3 outside cable core, fire-proof mud 4 is filled between Ceramic silicon rubber composite band 3 and cable core, in the outer uniform ring of Ceramic silicon rubber composite band 3 around many aramid fiber reinforced cores 5, fire retardant polyolefin oversheath 1 is wrapped in outside aramid fiber reinforced core 5.
Conductor is the stranded flexible conductor of copper wire.
