Abstract
The utility model discloses a novel flame-resistant cable, wherein a silicon rubber insulating layer, a synthetic mica tape, a steel wire armored layer and an outer sheath made of low-smoke halogen-free polyolefin cable materials are sequentially coated on the outside of the conductor of the cable. The silicon rubber insulating layer, the synthetic mica tape, the steel wire armored layer and the outer sheath are all excellent in flame-resistant and fire-proof properties. Thus, even if the cable is utilized close to open fire or at a high temperature, no toxic gas is released. Meanwhile, due to the adoption of the steel wire armored layer, the tensile property of the cable is improved. Therefore, the cable can bear a larger difference of level so as to be prevented from breaking even after the outer sheath is damaged.
Description
Technical field
The utility model belongs to the power cable technical field, especially can keep the cable of fire-retardant, fire-resistant, low cigarette, non-toxic nature in fire.
Background technology
At present, general fireproof power cable internal structure mainly adopts at conductor outer wrapping flame retardant coating, and oversheath adopts the low smoke and zero halogen material to reach fire-resistant, low cigarette, nontoxic performance.But usually fire resistance period is too short on fire resistance for existing flame-retardant fire-resistant control cable, can not adapt to better the requirement of hot environment.
Summary of the invention
In order to overcome existing fireproof power cable in the deficiency of fire resistance period aspect too short, the utility model provides a kind of novel flame resistant cable, the performance of low smoke and zero halogen when this novel flame resistant cable has good fire-resistant, burning.
The technical scheme that its technical problem that solves the utility model adopts is: the conductor outer wrapping silicone rubber insulation layer of novel flame resistant cable, silicone rubber insulation layer outer wrapping synthetic mica tape, synthetic mica tape outer wrapping wire armoring layer, wire armoring layer extrude the oversheath that the cable material of polyolefin by low smoke halogen-free forms outward.
Beneficial effect of the present utility model is, the oversheath that silicone rubber insulation layer, synthetic mica tape, wire armoring layer and low smoke halogen-free CABLE MATERIALS polyolefin form all has fire-retardant, fire-resistance property, even under naked light high temperature, can not discharge toxic gas yet, the wire armoring layer has improved the tensile property of cable, even so that cable after oversheath sustains damage, still can bear stronger drop and not rupture.
