The main function of the cable connector is to make the line unobstructed, to keep the cable sealed, and to ensure the insulation level at the cable joint for safe and reliable operation. If the sealing is poor, not only will the oil leakage cause the oil-impregnated paper to dry out, but moisture will also invade the inside of the cable, which will reduce the paper insulation performance.
Classification of cable joints
According to the installation location, it can be divided into indoor and outdoor.
According to the production and installation materials, it can be divided into heat-shrinking type (the most common one), dry-packing type, epoxy resin pouring type and cold shrinking type.
According to the core material, it can be divided into copper core power cable head and aluminum core power cable head.
According to the joint material, it is divided into plastic cable joint and metal cable joint. Metal cable joints are further divided into porous metal cable waterproof joints, anti-bending metal cable joints, double-locked metal cable waterproof joints, plastic hose cable joints, metal hose cable joints, and the like.
