Abstract

The utility model discloses a high-flexibility fireproof cable which is composed of cable cores and a protective outer layer, wherein the protective outer layer is wrapped outside the cable cores, filling material is arranged among the cable cores, each cable core includes a conductor wire core, a refractory layer and an insulating layer, the protective outer layer includes a fireproof inner sheath layer and a fireproof outer sheath layer, the conductor wire cores are formed by regularly twisting a plurality of soft copper wires with the same diameter, the refractory layers are machined with synthetic mineral refractory composite belts, the insulating layers are machined with cross-linked polyolefin halogen-free insulating material, the filling material is composed of alkali-free glass fiber ropes, the fireproof inner sheath layer is made of halogen-free low-smoke highly-flame-retardant glass ribbons, and the fireproof outer sheath layer is made of highly-flame-retardant low-smoke halogen-free polyolefin material. Compared with an ordinary fireproof cable, the high-flexibility fireproof cable has high-strength softness, environment-friendly and safe fireproof performance and excellent use performance, and communication and power lines in the fire are ensured to be open.

Description

The high flexibility fireproof cable
Technical field:
The utility model relates to a kind of cable, particularly relates to a kind of environment-friendly type porcelain SiClx rubber fireproof flexible cable, belongs to the electric wire field.
Background technology:
Fireproof cable of the prior art, mainly containing from outside to inside the structures such as oversheath, band, filler, insulation, flame retardant coating, conductor forms, its weak point is: the fireprotection layer of fireproof cable adopts mica tape directly wrapped at conductive surface usually, cable is in case burning, all organic materials that consist of cable will turn to dust and ashes, be exactly mica tape and wish keeps that " integrality of circuit " lean on, thereby the selection of mica tape and the processing technology particular importance that just seems.And cable less for bending radius, soft structure should not be made, because of the conductive surface out-of-flatness, fire-resistant isinglass belt is difficult to tight docilely in its surface wrapped, and simultaneously, core is more soft, the cross section is less, wrapped tension force is difficult to control suitably, and core swings larger, and mica layer easily comes off, mica can not be fully sintered in copper line surface, very easily causes the fire resistance test defective.
The utility model content:
Technical problem to be solved in the utility model is: for present situation and the problem of existing fire-resisting cable, provide a kind of high flexibility fireproof cable that does not adopt the fire prevention Mica tape.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of high flexibility fireproof cable, described high flexibility fireproof cable is made of a plurality of cable inner cores and protection skin, and described protection skin surrounds outside a plurality of cable inner cores, is provided with filler between a plurality of cable inner cores; Described cable inner core comprises conductor thread core, flame retardant coating and insulating barrier, and described protection skin comprises fire prevention sheath and fire prevention outer jacket.
Described conductor thread core is by some well-regulated stranded the forming of annealed copper wire that diameter is identical; Described flame retardant coating is processed by the fire-resistant composite band of synthetic mineral; Described insulating barrier is processed by cross-linked polyolefin Halogen insulating material.
Described filler is comprised of the alkali-free glass fibre rope; Described fire prevention sheath is comprised of the halogen-free low-smoke high-flame glass tape; Described fire prevention outer jacket is formed by the materials processing of high flame resistance, low smoke halogen-free polyolefin.
The beneficial effects of the utility model are as follows:
Conductor thread core of the present utility model is by some well-regulated stranded the forming of annealed copper wire that diameter is identical, has the advantages such as softness, loaded current be large; Flame retardant coating is processed by the fire-resistant composite band of synthetic mineral, does not contain organic insulating polymeric material, thereby gets rid of the generation of carbon granules; Insulating barrier is processed by cross-linked polyolefin Halogen insulating material, has high temperature resistant, corrosion-resistant, the performances such as volume is little, high insulating property, low smoke, zero halogen; Protective layer adopts the halogen-free low-smoke high-flame material; Filler adopts the alkali-free glass fibre material, the fire prevention sheath is comprised of the halogen-free low-smoke high-flame glass tape, the fire prevention outer jacket is formed by the materials processing of high flame resistance, low smoke halogen-free polyolefin, make cable have the advantages such as corrosion-resistant, acid and alkali-resistance, oil resistant, fire-retardant, low smoke, zero halogen, the performance such as non-corrosiveness and toxicant and γ-ray emission during burning, pollution-free, environmental protection.
The utility model is applicable to explosion protection system and equipment, fire hazard zone, high temperature occasion, underground line and requires the occasions such as ultra-safe facility, be used as the transmission ﹠ distribution electric energy, the premium properties such as have fire prevention, low temperature resistant, corrosion-resistant, ampacity is large, mechanical strength is high, volume is little, lightweight, life-span long, good ground connection performance, water resistance is good, especially less to the bending radius requirement, require the higher occasion of soft intensity particularly applicable.
The utility model is compared with common fireproof cable and is had more wear-resistant, warp resistance, anti-aging, tear-proof, the characteristic such as corrosion-resistant, flexibility and tensile property are strong, the flame-retardant performance of cable is stronger, guaranteed the unimpeded of in fire communication and power circuit, for the valuable time has been won in the rescue of life and property.
The property that the utility model utilizes insulating barrier and protective materials to have has improved the quality stability of fireproof cable, for new technical field has been opened up in the development of fireproof 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 further described:
Referring to Fig. 1, a kind of high flexibility fireproof cable, consisted of by a plurality of cable inner cores and protection skin, the protection skin surrounds outside a plurality of cable inner cores, be provided with filler 4 between a plurality of cable inner cores, the cable inner core comprises conductor thread core 1, flame retardant coating 2 and insulating barrier 3, and the protection skin comprises fire prevention sheath 5 and fire prevention outer jacket 6.Wherein: conductor thread core (1) is by some well-regulated stranded the forming of annealed copper wire that diameter is identical, flame retardant coating 2 is processed by the fire-resistant composite band of synthetic mineral, insulating barrier 3 is processed by cross-linked polyolefin Halogen insulating material, filler 4 is comprised of the alkali-free glass fibre rope, fire prevention sheath 5 is comprised of the halogen-free low-smoke high-flame glass tape, and fire prevention outer jacket 6 is formed by the materials processing of high flame resistance, low smoke halogen-free polyolefin.
The utility model is applicable to explosion protection system and equipment, fire hazard zone, high temperature occasion, underground line and requires the occasions such as ultra-safe facility, be used as the transmission ﹠ distribution electric energy, compare fire protecting performance with high strength flexible performance, Environmental Safety and good serviceability with common fireproof cable, guaranteed the unimpeded of in fire communication and power circuit.
