Abstract
The utility model discloses a fireproof and flame-retardant shielding type control cable. Each conductor is made of a single strand of soft copper wires; two layers of mica tapes are wrapped on each conductor to form a fireproof layer; a crosslinked polyethylene insulating layer is extruded on each fireproof layer to form an insulated wire core; the insulated wire cores and flame-retardant ropes are stranded together, and two layers of mica tapes are wrapped on the combination of the insulated wire cores and the flame-retardant ropes, so that a second fireproof layer is formed; a shielding layer, a sheath layer and an outer protecting layer are respectively arranged on the second fireproof layer form inside to outside; the shielding layer is woven from composite aluminum-plastic tapes and copper wires; the sheath layer is extruded and formed from a zero-halogen low-smoke polyolefin material; and the outer protecting layer is extruded and formed from a thermoplastic fireproof polyolefin. The insulating performance of the cable can keep excellent under the condition of high-temperature combustion, and the cable can continuously run in high-temperature flame.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of fire protection flame retarding shielding-type control cable.Belong to technical field of electric wires and cables.
Background technology
Development along with the comprehensive wiring industry, especially the rise of data center, people more and more pay attention to data safety, cable is as the highway of communication, it just becomes the popular domain of various countries engineer research naturally for the resistance ability of outburst disaster in the middle of transmission course, also just become the most important thing as the fire prevention first of the comprehensive wiring " three is anti-".
Fire can burn comprehensive wiring system, and Internet Transmission is interrupted.Simultaneously, if cable produces a large amount of toxic gases and flue dust in combustion process, can produce on personnel's escape greatly impact so, even become safe hidden danger.Therefore, the engineers of various countries is all studied for data backup and the safer fireproof cable of personnel stepping up.
The utility model content
A kind of fire protection flame retarding shielding-type control cable of the utility model requires still can keep good insulation property at cable in the high-temp combustion situation, can continuously operation in thermal-flame.
Scheme of the present utility model is as follows: a kind of fire protection flame retarding shielding-type control cable, conductor adopt solely strand soft copper silk, and wrapped two-layer mica tape forms fireprotection layer on described conductor, extrude crosslinked polyetylene insulated layer on the described fireprotection layer and form insulated wire cores; Thoroughly do away with the edge cores and flame-retardant rope twists together and wrapped two-layer mica tape forms the second fireprotection layer more, be respectively arranged with from inside to outside screen, restrictive coating, outer jacket on described the second fireprotection layer; Described screen adopts aluminium-plastic tape and proof copper-wire braided, and described restrictive coating adopts the low smoke, zero halogen polyolefine material to extrude moulding, and described outer jacket adopts thermoplasticity fire prevention polyolefin to extrude moulding.
The beneficial effects of the utility model:
1, the utility model cable cover(ing) adopts the low smoke, zero halogen polyolefin jacket, because the low smoke, zero halogen polyolefin jacket has well the characteristics such as fire-retardant, high mechanical properties.
2, the utility model extrudes one deck thermoplastic halogen-free fire prevention polyolefin jacket material in the oversheath outside, can effectively prevent the burning of flame, improves the fireproofing of cable performance.
3, the utility model conductor and cable core wrapped double-layer alloy mica tape respectively improves the fireproofing of cable performance, prolongs cable useful life.
4, aluminium-plastic tape and proof copper-wire braided shielding are adopted in this practicality, have good shielding properties and interference free performance, have improved greatly the shielding properties of cable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of fire protection flame retarding shielding-type control cable, conductor 1 adopt solely strand soft copper silk, and wrapped two-layer mica tape forms fireprotection layer 2 on described conductor 1, extrude crosslinked polyetylene insulated layer 3 on the described fireprotection layer 2 and form insulated wire cores; Thoroughly do away with the edge cores and flame-retardant rope 4 twists together and wrapped two-layer mica tape forms the second fireprotection layer 5 more, be respectively arranged with from inside to outside screen 6, restrictive coating 7, outer jacket 8 on described the second fireprotection layer 5; Described screen 6 adopts aluminium-plastic tape and proof copper-wire braided, and described restrictive coating 7 adopts the low smoke, zero halogen polyolefine material to extrude moulding, and described outer jacket 8 adopts thermoplasticity fire prevention polyolefin to extrude moulding.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
