Abstract
The invention discloses a fireproof power cable and belongs to the technical field of cables. The fireproof multi-core power cable includes a cable core which is formed by twisting insulating cables. The outside of the cable core is sequentially provided with a wrapping layer, an inner sheath layer, a stainless steel band armored layer and an outer sheath layer. A filling material is arranged between the cable core and the wrapping layer. Each insulating cable includes a conductor, and the outside of the conductor is sequentially provided with a shielding layer, a mica layer, and an insulating layer. The fireproof multi-core power cable is reasonable in design. The conductors are externally provided with the mica layers, which improves the fire resistance of products and enables the cable to work normally at high temperature. The intensity of products is improved due to the arrangement of the stainless steel band armored layer. Due to the arrangement of the flame-resistant polyvinyl fluoride outer sheath layer, the glass flame-resistant belt wrapping layer and the flame-resistant polypropylene filling rope, the flame resistance of products is improved, and products are ensured to work normally in special occasions.
