Abstract

The invention discloses an anti-corrosion and fire-resistant cable, which comprises a cable body, a sub-conductive part, a female conductive part, a fireproof sleeve, a heat-shrinkable tube, a rotating cover, a sub-joint tube and a female joint tube, and in the cable body, an outer layer of a conductive core It is fixedly connected to the inner layer of the insulating layer, and the outer layer of the insulating layer is fixedly connected to the aluminum sleeve. The aluminum sleeve is a hollow cylinder with aluminum sleeve legs evenly distributed on the periphery. The ends of the aluminum sleeve legs are fixedly connected to the mica tape. Two adjacent aluminum sleeve legs The mineral filling layer is filled between the mica tape and the heat conduction ring. The heat conduction ring is a thin-walled hollow cylinder and the heat conduction ring feet are evenly distributed on the inside of the cylinder. The heat absorbed by the aluminum sleeve is then transferred to the surface of the lower temperature anti-corrosion layer, which reduces the temperature of the cable core and increases the temperature of the surface of the anti-corrosion layer to keep it dry and prevent water corrosion.

Description

technical field

[0001] The invention relates to the technical field of cables, in particular to an anti-corrosion and fire-resistant cable. Background technique

[0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulated covering layer, the cable has the characteristics of internal energization and external insulation. The cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, and mining cables. Cables, aluminum alloy cables, etc., they are composed of single or multi-strand wires and insulation layers, used to connect circuits, electrical appliances, etc.

[0003] The existing cables have poor anti-corrosion performance. In some humid areas, the anti-corrosion layer on the surfa...
