Description
Technical field
The utility model is related to cable and wire technical field, it particularly relates to a kind of heat and flame environment-friendly type low tension
Cable.
Background technology
In the prior art, low-voltage cable generally uses packing material, sheath generally have the non-environmental protection type of flame retardant type
The netted polypropylene tearing rope of filling and twining package tape, such as asbestos layer, glass fiber tape or environmentally friendly class, non-woven fabrics etc., but it is above-mentioned
The equal Shortcomings of cable, non-environmental protection material generally takes chemical material, after cable service life is long, is not easy subsequent processing,
And fire-retardant non-environmental protection material can discharge a large amount of smog and toxic gas in flame, the hidden danger easily caused；For
Non-flame resistant environment-friendly materials, packing material and sheath can carbonize in flame, it is impossible to effective protection conducting wire.
For the problems in the relevant technologies, currently no effective solution has been proposed.
Utility model content
For the above-mentioned technical problem in the relevant technologies, the utility model proposes a kind of heat and flame environment-friendly type low tensions
Cable can improve the heat and flame ability of cable, while using environment-friendly materials, conducive to the processing of cable, avoid cable in high temperature
Or burn under environment, discharge noxious material.
To realize the above-mentioned technical purpose, the technical solution of the utility model is realized in：
A kind of heat and flame environment-friendly type low-voltage cable, including cable core, the cable core is strengthened by several copper conductors and one
Core is twisted, and the cable core is wrapped with ceramic glass layer, the ceramic glass layer and the cable core it
Between gap in filled with quartz sand, clad steel belt, the bilayer steel belt layer are provided with outside the ceramic glass layer
It is wrapped with oversheath；Insulation twining package tape is enclosed on the copper conductor.
Further, wrapped Duplication >=25% of the overlapping of the insulation twining package tape.
Further, the insulation twining package tape is ceramic glass fibre or rubber.
Further, the strengthening core is supported for aramid fiber.
Further, the oversheath is halogen-free and low-smoke flame-retardant polyolefin oversheath.
The beneficial effects of the utility model：Filler of preventing fires is filled using quartz sand, and wrapping layer uses glass-ceramic fiber,
With good fire-proof high-temperature resistant property, and in use, because of high temperature and generation poisonous smog or gas will not be burnt
Body after cable bad or service life arrive, can be more convenient to handle.

Body, and when handling discarded or damage cable, do not need to carry out individual specially treated to quartz sand 6, be conducive to environment
Protection.
In a specific embodiment of the utility model, the wrapped Duplication of overlapping of the insulation twining package tape 5 >=
25%, protection and insulation from each other are preferably carried out to copper conductor 1, while avoid rubbing between copper conductor 1 and quartz sand 6
Wiping causes to damage.
In a specific embodiment of the utility model, the insulation twining package tape 5 is ceramic glass fibre or rubber.
In a specific embodiment of the utility model, the strengthening core 2 is supported for aramid fiber, can be good at increasing
The toughness of forceful electric power cable facilitates the construction of cable to be laid with.
In a specific embodiment of the utility model, the oversheath 7 is halogen-free and low-smoke flame-retardant polyolefin oversheath,
The substance of environment is influenced without lead cadmium chromium mercury etc., when burning will not send out toxic smog.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
