AI Technical Summary
Existing medium-voltage power cables are easily corroded by soil moisture in humid environments, resulting in a shortened service life.
A double-layer water-blocking structure combining an inner water-blocking layer and an outer water-blocking layer is adopted, and the cable body is lifted away from the soil layer by a moisture-proof sleeve. The moisture-proof sleeve includes components such as a protective sleeve, a left cylinder, and a right cylinder to limit the contact between the damp soil layer and the cable surface.
It significantly improves the operational stability and service life of cables in humid environments, enhances waterproof performance, and extends the service life of cables.
