Mineral fireproof cable is used for important electrical engineering field, such as deathtrap: airport, oil depot, liquefied gas station, chemical industry, colliery, (core) power station, smelting iron and steel and shipbuilding etc.;Senior important communal facility: ground satellite station, railway distribution line, warning, fire-fighting etc.;Guarantee personal safety as well as the property safety place: historical building, hotels, skyscraper, museum, library, bank, hospital, insurance, market, scientific research institution etc..
The present invention has following features.
(1) fire protecting performance.
Use inorganic material in a large number due to mineral cable, itself will not cause fire, it is impossible to burning or combustion-supporting, more will not produce poisonous gas, even if there being outward the burning at flame, cable still can normally work.
(2) waterproof, explosion-proof, corrosion-resistant.
Due to dense compaction body between cable conductor, insulation and sheath three.Thus make it not only have the infringement preventing water, moisture, oil and some chemical substances, thus it is practically applicable to have the local and various antiknock device of explosion danger, the line of equipment.
(3) overload protection.
During circuit overload, plastic cable can cause insulation heating or puncture because of overcurrent or overvoltage.And for mineral insulated cable, as long as heating does not reaches the melting temperature of copper, cable is not damaged.Even if moment punctures, at breakdown point, magnesium oxide high temperature also will not form carbide.After overload is removed, cable performance will not change, and may continue to normally use.(4) operating temperature is high.
Melting temperature due to mineral insulation layer is far above the melting temperature of copper, thus the highest normal work high temperature of cable is up to 250 DEG C.Short-term can continue running at the melting temperature 1083 DEG C of copper.
(5) shielding properties is strong.
It is provided with aluminium foil layer 8 between cable Ceramic silicon rubber layer 6 and flame protection set 7 and flame protection set is best shielding protection layer, the cable interference to other cables itself can be prevented, can prevent again external magnetic field from self must be disturbed.
(6) life-span is long.
Owing to the present invention uses inorganic material, in a large number because without ageing, its useful life is minimum reaches more than a century in structure design.And this cable can again dismount with equipment displacement or track remodelling, reuse.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
