Detailed Description
The following describes the present invention with reference to the accompanying drawings.
As shown in fig. 1, a fireproof cable, includes the cable body, the inside sinle silk 1 that is equipped with of cable body, sinle silk 1 quantity is three and outside once cup joints and is equipped with mineral substance insulating layer one 2, fire-retardant layer one 3 and insulating layer 4, the cable body is still including setting gradually at three sinle silk 1 outlying copper sheathing isolation layers 6, mineral substance insulating layer two 7, tensile layer 8, fire-retardant layer two 9, elastic layer 10, waterproof layer 11, anti-corrosion coating 12 and wearing layer 13, be equipped with shock attenuation filler 5 between the outermost insulating layer 4 of sinle silk 1 and copper sheathing isolation layer 6.
The mineral insulating layer I2 and the mineral insulating layer II 7 are both mica layers.
The first flame-retardant layer 3 and the second flame-retardant layer 9 are both made of mineral glass magnesium fireproof materials.
The heat insulation layer 4 is made of glass fiber.
The tensile layer 8 is of a steel wire belt net structure.
The elastic layer 10 is a polyurethane elastic layer.
The waterproof layer 11 is made of high-temperature-resistant polytetrafluoroethylene.
The anti-corrosion layer 12 is made of polyphenylene sulfide.
The wear-resistant layer 13 is made of polytetrafluoroethylene.
