Abstract
The utility model discloses a low-smoke halogen-free type flexible cable, wherein four cores formed by conductors wrapped with silicon rubber insulating layers of different colors are evenly distributed at the periphery of a central strengthening rib and are twisted with the central strengthening rib to form a cable core. The exterior of the cable core is orderly provided with a mica tape, a copper wire shielding layer and low-smoke halogen-free type polyolefin cable materials to form an outer sheath. The silicon rubber insulating layers, the mica tape and the outer sheath are flame-retardant and fireproof. Even when close to heat or open flames, the silicon rubber insulating layers, the mica tape and the outer sheath do not release any toxic gas. The cable can bear a larger drop and is prevented from being broken even when the outer sheath is damaged due to the adoption of the central strengthening rib. The interference of external electromagnetic signals on the internal conductors of the cable is shielded by the copper wire shielding layer.
Description
Technical field
The utility model belongs to soft control cables technical field, especially can keep the cable of fire-retardant, fire-resistant, low cigarette, non-toxic nature in fire.
Background technology
At present, general low smoke and zero halogen control cables 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 low smoke and zero halogen control cables in the deficiency of fire resistance period aspect too short, the utility model provides a kind of low smoke halogen-free control flexible cable, and that this low smoke halogen-free control flexible cable has is fire-resistant, the performance of low smoke and zero halogen during burning.
The technical scheme that its technical problem that solves the utility model adopts is: four cores are evenly distributed in around the reinforcement of center, four cores are comprised of the silicone rubber insulation layer of conductor outer wrapping different colours respectively, core and center reinforcement are twisted into cable core, cable core outer wrapping mica tape, mica tape outer wrapping shielding layer of copper wires, shielding layer of copper wires extrude the oversheath that the cable material of polyolefin by low smoke halogen-free forms outward.
A kind of prioritization scheme of such scheme is: described center reinforcement is stainless steel wire.
Beneficial effect of the present utility model is, the oversheath that silicone rubber insulation layer, mica tape and low smoke halogen-free CABLE MATERIALS polyolefin form has fire-retardant, fire-resistance property, even under naked light high temperature, can not discharge toxic gas yet, the center reinforcement has improved the tensile property of cable, even so that cable still can bear stronger drop and not rupture after oversheath sustains damage, shielding layer of copper wires has stoped extraneous electromagnetic signal to the interference of inner conductor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. conductors among the figure, 2. silicone rubber insulation layer, 3. stainless steel wire, 4. mica tape, 5. shielding layer of copper wires, 6. oversheath.
Embodiment
In Fig. 1, four cores are evenly distributed in around the stainless steel wire 3, four cores are comprised of the silicone rubber insulation layer 2 of conductor 1 outer wrapping different colours respectively, core and stainless steel wire 3 are twisted into cable core, cable core outer wrapping mica tape 4, mica tape 4 outer wrapping shielding layer of copper wires 5, shielding layer of copper wires 5 is outer to extrude the oversheath 6 that the cable material of polyolefin by low smoke halogen-free forms.
