Abstract
The invention discloses an anti-stretching electric wire with a fireproof function. The anti-stretching electric wire comprises a wire core and a wire housing arranged on the outer surface of the wire core. The wire housing comprises an inner layer, a middle layer and an outer layer. The inner layer is internally provided with a flexible wrapping tape which is formed by horizontal inner belts and vertical outer belts, wherein the vertical outer belts are uniformly arranged on the outer surfaces of the horizontal inner belts, and a buffering interval exists between each two vertical outer belts. The middle layer is internally provided with a fireproof combination body. Chlorinated rubber, chlorinated paraffin, alumina and asbestos powder are combined to form the fireproof combination body. Alumina is arranged at the outer side of chlorinated rubber. According to the invention, the tensile strength of the electric wire is effectively improved, the stability of the housing of the electric wire is improved under the condition that the electric wire is pulled by a pulling force, an inward contracting phenomenon of the wire core in the electric wire under the effect of the pulling force is effectively avoided, the wire core is effectively prevented from being broken, and the electric wire has a good fireproof effect.
