This cable has characteristics such as fine resistant oil, wear -resisting, high temperature resistant and fire resistance rating height to the little construction convenience of bend radius.

Description

A kind of flexible ceramic SiClx rubber-covered fireproof cable

Technical field

The utility model is specifically related to a kind of flexible ceramic SiClx rubber-covered fireproof cable.

Background technology

Along with China's expanding economy, various architectural engineering is with unprecedented scale and speed development, also more and more higher to the requirement of electric equipment.In recent years, because the fire electrically caused gets more and more, and wherein electric wire reason and the fire caused occupies sizable ratio, at present, the cable type that market at different levels uses is various, quality is uneven, respectively has its defect, for safety fire fighting etc. brings certain hidden danger.Existing fireproof cable all adopts copper sheath structure, has had a strong impact on Cable Bending Radius, although improve significantly, also has significant limitation curved qualitatively by radius and fire prevention.

Utility model content

The purpose of this utility model is the shortcoming overcoming prior art, provides the flexible ceramic SiClx rubber-covered fireproof cable that a kind of bending radius is little, fire resistance rating is high.

For achieving the above object, technical solution adopted in the utility model is: provide a kind of flexible ceramic SiClx rubber-covered fireproof cable, comprise many stranded insulated power cores, insulated power core by some stranded oxygen-free copper conductors and wrapped mica twining package tape outside oxygen-free copper conductor, and is extruded in the Ceramic silicon rubber insulating barrier composition outside mica twining package tape;

LSOH anti-flaming twining package tape is surrounded with outside the insulated power core twisted together, Halogen gasket for packing is filled with between LSOH anti-flaming twining package tape and insulated power core, Ceramic silicon rubber twining package tape is surrounded with outside LSOH anti-flaming twining package tape, Ceramic silicon rubber twining package tape is coated with low smoke, zero halogen inner sheath, low smoke, zero halogen inner sheath is coated with the chain armouring of galvanized steel strip, and the chain armouring of galvanized steel strip is coated with low smoke, zero halogen oversheath.

As preferably, insulated power core has 2 ~ 5.

the beneficial effects of the utility model are:

1, the utility model comprises many stranded insulated power cores, and insulated power core by some stranded oxygen-free copper conductors and wrapped mica twining package tape outside oxygen-free copper conductor, and is extruded in the Ceramic silicon rubber insulating barrier composition outside mica twining package tape.LSOH anti-flaming twining package tape is surrounded with outside the insulated power core twisted together, Halogen gasket for packing is filled with between LSOH anti-flaming twining package tape and insulated power core, Ceramic silicon rubber twining package tape is surrounded with outside LSOH anti-flaming twining package tape, Ceramic silicon rubber twining package tape is coated with low smoke, zero halogen inner sheath, low smoke, zero halogen inner sheath is coated with the chain armouring of galvanized steel strip, and the chain armouring of galvanized steel strip is coated with low smoke, zero halogen oversheath.This cable has the characteristics such as good oil resistant, wear-resisting, high temperature resistant and fire resistance rating be high, and the little easy construction of bending radius.

Accompanying drawing explanation

Fig. 1 is an example structure schematic diagram of the present utility model.

Wherein: 1, insulated power core; 2, oxygen-free copper conductor; 3, mica twining package tape; 4, Ceramic silicon rubber insulating barrier; 5, Halogen gasket for packing; 6, LSOH anti-flaming twining package tape; 7, Ceramic silicon rubber twining package tape; 8, low smoke, zero halogen inner sheath; 9, the chain armouring of galvanized steel strip; 10, low smoke, zero halogen oversheath.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.

With reference to figure 1, the present embodiment provides a kind of flexible ceramic SiClx rubber-covered fireproof cable, comprise many stranded insulated power cores 1, insulated power core 1 is by some stranded oxygen-free copper conductors 2 and wrapped mica twining package tape 3 outside oxygen-free copper conductor, and the Ceramic silicon rubber insulating barrier 4 be extruded in outside mica twining package tape 3 forms;

LSOH anti-flaming twining package tape 6 is surrounded with outside the insulated power core 1 twisted together, Halogen gasket for packing 5 is filled with between LSOH anti-flaming twining package tape 6 and insulated power core 1, Ceramic silicon rubber twining package tape 7 is surrounded with outside LSOH anti-flaming twining package tape 6, Ceramic silicon rubber twining package tape 7 is coated with low smoke, zero halogen inner sheath 8, low smoke, zero halogen inner sheath 8 is coated with the chain armouring 9 of galvanized steel strip, and the chain armouring 9 of galvanized steel strip is coated with low smoke, zero halogen oversheath 10.Insulated power core 1 has 2 ~ 5.

In implementation process, by stranded for some oxygen-free copper conductors 2 rear wrapped mica twining package tape 3, extrude Ceramic silicon rubber insulating barrier 4 outside mica twining package tape 3 thus make insulated power core 1, then carrying out spark test.

Get four stranded through the insulated power core 1 that spark test is qualified, thoroughly do away with the outer wrapped LSOH anti-flaming twining package tape 6 of edge power wire core 1 stranded four, and fill Halogen gasket for packing 5 between LSOH anti-flaming twining package tape 6 and insulated power core 1.At the outer wrapped Ceramic silicon rubber twining package tape 7 of LSOH anti-flaming twining package tape 6, at Ceramic silicon rubber twining package tape 7 outer cladding low smoke, zero halogen inner sheath 8, at the chain armouring 9 of low smoke, zero halogen inner sheath 8 outer cladding galvanized steel strip, make cable at galvanized steel strip chain armouring 9 outer cladding low smoke, zero halogen oversheath 10, finally carry out spark test and whether routine test test cable is qualified.

Oxygen-free copper conductor 2 has high electrical conductivity energy and mechanical performance.Mica twining package tape 3 can keep certain insulation property within a certain period of time when burning.Ceramic silicon rubber insulating barrier 4 and Ceramic silicon rubber twining package tape 7 have performance that is fire-resistant, fire-retardant, LSZH, after its burning, residue is ceramic-like duricrust, duricrust not melting under fire hazard environment (600-13000C), not dripping, increasing cable keeps circuit integrality time when burning greatly.LSOH anti-flaming twining package tape 6 and low smoke, zero halogen inner sheath 8 have fire-retardant and heat-proof quality and can not discharge toxic gas when cable fire very well, avoid secondary injury.The chain armouring of galvanized steel strip 9 can bear certain mechanical stress therefore cable installation time do not need crane span structure.Low smoke, zero halogen oversheath 10 has fire-retardant, corrosion-resistant, high temperature resistant and can not discharge toxic gas when cable fire, avoids secondary injury etc.

This cable also can only have an eradication edge power wire core 1, need not fill Halogen gasket for packing 5 when insulated power core 1 only has one between LSOH anti-flaming twining package tape 6 and insulated power core 1.

Above-mentioned execution mode is used for explaining and the utility model is described; instead of the utility model is limited; in the protection range of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection range of the present utility model.
