Abstract
The utility model discloses an environment-friendly split-phase shielded fire-resistant control flexible cable, which comprises a cable core. The cable core comprises one or more insulated wire cores of which the outsides are coated with a glass fiber band layer; a sheath is arranged outside the glass fiber band layer; and a gap between the insulated wire core and the glass fiber band layer is filled with high flame-retardant filling ropes. The environment-friendly split-phase shielded fire-resistant control flexible cable is characterized in that: the insulated wire core comprises a plurality of twisted copper conductors; the outside of the twisted copper conductors is coated with a fire-resistant mica layer; the outside of the fire-resistant mica layer is coated with a crosslinked polyethylene insulation layer; and the outside of the crosslinked polyethylene insulation layer is provided with a shielding layer. The environment-friendly control flexible cable has the advantages of high fire resistance, excellent shielding performance and easy installation and laying so as to meet the requirements of intensive laying of the cables in modern large high-end buildings and subways.
Description
Technical field:
The utility model relates to main and a kind of cable, relates in particular to a kind of environment-friendly type phase-splitting and shields fire-resistant control flexible cable.
Background technology:
Our employed fireproof control cable major part is polyvinyl chloride insulation and pvc sheath for a long time, the disadvantage of this kind cable insulate exactly and sheath material all contains halogen, under the condition of breaking out of fire, because its amount of being fuming is big, cause the survivor in the escape process, to be poisoned dead by toxic gas.
In addition, the control cable of common shield type, if there is screen to be total shielding, promptly screen is arranged on outside the cable core, does not consider the signal interference problem between its each heart yearn.
The utility model content:
The purpose of this utility model is exactly in order to remedy the deficiency of prior art, to provide the environment-friendly type phase-splitting to shield fire-resistant control flexible cable, solved general cable when fire, discharging the problem that the signal between toxic gas and each heart yearn disturbs.
The utility model is achieved through the following technical solutions:
A kind of environment-friendly type phase-splitting shields fire-resistant control flexible cable, includes cable core, and described cable core includes one or several insulated wire cores, insulated wire cores outer wrapping glass fibre belt, and the glass fibre belt is outside equipped with sheath; The high flame retardant gasket for packing that fill in the gap between described insulated wire cores and the glass fibre belt, it is characterized in that: described insulated wire cores includes many twisted copper conductors, described twisted copper conductors is wrapped with fire-resistant mica layer, described fire-resistant mica layer is wrapped with crosslinked polyetylene insulated layer, the outer screen that is provided with of described crosslinked polyetylene insulated layer.
Described environment-friendly type phase-splitting shields fire-resistant control flexible cable, it is characterized in that: described screen is the copper wire organization level.
Described a kind of environment-friendly type phase-splitting shields fire-resistant control flexible cable, it is characterized in that: described sheath is a low-smoke halide-free fireproof composite polyolefine material.
The friendly section bar material with the equal environment for use of sheath of the utility model insulation even cable burning under the chance fire condition is can not produce harmful gas, is guaranteed personal safety; Adopt the shielding construction of copper wire braid, be better than the common in the market structure that screen is set on cable core, can guarantee that cable avoids the signal between core to disturb when laying.
The utility model has the advantages that:
The utility model is that a kind of fire resistance is strong, shielding properties is superior, is easy to install the environment-friendly type control flexible cable that lays, to be adapted to modernized large-scale top-grade building, the intensive needs that lay of cable in the subway.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
A kind of environment-friendly type phase-splitting shields fire-resistant control flexible cable, include cable core, cable core is by the glass fibre belt 6 outside three insulated wire cores 8 and the wrap insulate core 8, sheath 7 is arranged outside the glass fibre belt 6, and the high flame retardant gasket for packing 5 that fill in the gap between insulated wire cores 8 and the glass fibre belt 6 is formed, described insulated wire cores 8 includes many twisted copper conductors 1, twisted copper conductors 1 is wrapped with fire-resistant mica layer 2, fire-resistant mica layer 2 is wrapped with crosslinked polyetylene insulated layer 3, the crosslinked polyetylene insulated layer 3 outer screen 4 that is provided with.
Claims (3)
