Watertight and antiseptic power cable and manufacturing method thereof

Abstract

The present invention discloses a watertight and antiseptic power cable and a manufacturing method thereof. The power cable comprises a cable core. The cable core is mainly composed of a plurality of strands of insulated conductors. Each strand of insulated conductor is mainly composed of a conductor and an insulating layer coated outside the conductor, wherein the insulated conductor is of a single solid-core aluminum alloy conductor structure, and a conductor water-resistant layer is coated onto the conductor. The periphery of the cable core is sequentially coated with a cable core water-resistant layer, a protective layer, an armor layer, a grapheme-asphalt layer, a water blocking isolation layer, a flame-retardant layer and a sheath layer from inside to outside. According to the technical scheme of the invention, the long-acting, stable, reliable and safe service of the power cable can be realized in a water environment and/or a humid environment. Meanwhile, the power cable is high in practicability.

Description

technical field [0001] The invention relates to a power cable, in particular to a watertight and anti-corrosion power cable and a method for manufacturing the cable. The cable is particularly suitable for use in a water environment and / or a humid environment. Background technique [0002] As power transmission cables, power cables inevitably need to be laid and used in water environment (such as river bottom or seabed) and / or wet environment according to the working environment or cable erection route. However, water, the main component in water environment and / or humid environment, is relatively harmful or even fatal to cables; therefore, cables used in water environment and / or humid environments must consider the waterproofing of cables sex and corrosion resistance. [0003] Conventional waterproof and anti-corrosion power cables are mainly realized by setting a water-blocking layer and anti-corrosion sheath of functional structure around the cable core. The waterproof a...

AI Technical Summary

Problems solved by technology

Although the cable formed by this technology has certain moisture-proof and waterproof characteristics, its anti-corrosion performance is poor. Functional structure - the functional structure lacks the corresponding anti-corrosion ability

It can be seen that although this technology has a certain waterproof function, its anti-corrosion performance is poor, and it cannot meet the long-term, stable, reliable and safe service requirements in water environment and / or humid environment, and its practicability is poor.
