Abstract
The invention discloses a (6-10) KV and (6-10) KV below silicon rubber insulating refractory flat flexible cable. The flat flexible cable is characterized by consisting of a conductive layer, a semiconductor layer, a silicon rubber insulating layer, an outer semiconductor layer, a copper wire braiding shielding layer and a porcelainized silicon rubber sheath from the inside to the outside sequentially, wherein the porcelainized silicon rubber sheath consists of methyl vinyl silicone rubber, white carbon ash, silicon oil and porcelainized powder. The invention breaks through the bottleneck that the (6-10) KV and (6-10) KV below flat flexible cable cannot resist flame, and multiple winding of mica tapes are not required, so that the cost is greatly reduced, short circuit or broken circuit is prevented when the cable is burnt for 90 minutes at the temperature between 750 and 950 DEG C.
Description
Technical field
The present invention relates to a kind of fire-resisting cable and preparation method thereof, particularly a kind of 6-10KV and the flat flexible cable of following silicon rubber insulation fire-resistant.
Background technology
The range of application of flat flexible cable may be summarized to be substantially and is used for rail system, transmission line, lifting, elevator, rotary machine, quayside container crane, be adapted at equally moving repeatedly on the horizontal plane and the powerful occasion that bends, and be fit to dry and moist indoor use, this cable keeps good flexibility under harsh conditions, utilization rate is high.
From its purposes as can be seen, not only be used for industrial equipment and production, also be applied to daily life, and skyscraper and public place of entertainment are the multiple ground of fire, though fire prevention measure need be arranged in building and public place of entertainment,, still can cause fire because combustibles are deposited in a large number.If at high temperature fire resistance is bad for some corresponding illuminations or cable conveying system, then can bring very big trouble to the rescue of fire.
The fire-resisting cable of prior art can be at the outside mica tape that coats of silicone rubber jacket, because mica tape is fire-resistant, can make the cable at high temperature still can operate as normal, but mica tape need be through repeatedly twining, and is time-consuming, and productivity ratio is reduced greatly, and owing to require more and more higher to the cable fire resistance, the research that improves its refractory temperature for changing the mica tape composition proportion, also a large amount of carrying out, the cable production that these all improve and the cost of correlative study.Especially the flat flexible cable of 6-10KV increases its fire resistance, and difficulty is bigger.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the exhausted gorgeous fire-resistant flat flexible cable of a kind of 6-10KV and following silicon rubber, by silicon rubber is carried out modification, make its porcelainization, improve its fire resistance, and need not to twine mica tape, reduce production costs significantly.
The present invention realizes by following technical scheme:
A kind of 6-10KV and the flat flexible cable of following silicon rubber insulation fire-resistant, described cable is followed successively by conductor layer, semiconductor layer, silicone rubber insulation layer, outer semiconducting layer, copper wire woven shield and porcelain silicone rubber jacket from inside to outside.
