Answer: To ensure a waterproof and durable connection for underground cables, the best practice involves using specialized underground cable laying equipment and jointing techniques that protect against moisture and environmental factors. After preparing the cable ends, the conductors are joined using a mechanical or compression connector. The joint is then sealed using a kit that provides insulation and moisture protection. Common methods include heat shrink jointing, which uses heat to tightly seal the connection, and cold shrink jointing, which involves a pre-expanded sleeve that contracts on its own. For high-voltage applications, resin jointing is often used, where a resin compound is poured into a mold around the splice, creating a solid, protective enclosure. Our comprehensive product line includes the necessary underground cable laying equipment and tools to perform these tasks efficiently and safely, from cable rollers and hydraulic crimpers to specialized cutting tools.
