Background
With the continuous and rapid development of urbanization, an overhead power supply line is gradually replaced by a power cable, and a power cable body and cable accessories (a cable terminal connector accessory and an intermediate connector accessory) can be manufactured by professional manufacturers according to the national standard, but the installation of the cable accessories needs to be completed on a construction site. The cable accessories are mainly used for connecting various electrical equipment such as switches, transformers and cables, the running conditions are more strict than the requirements of a cable body, more requirements than the cable body are provided, the structure is more complex, the technical difficulty is higher, and the cable accessories mainly comprise four key technologies: conductor connection technology, electric field control technology, insulation technology, sealing technology, and the cable body is very heavy, and the installation work can be calculated as high-precision heavy physical labor.
If process defects exist in the installation process, the cable can be in fault in operation, and power failure accidents are caused. However, in such a critical construction link, the construction personnel can operate the tool completely by hand, the used tools are only common art designing tools, handsaws, vices, files, tape measures and abrasive paper, the most used auxiliary tools are only manual hydraulic pliers which are used when a metal cable joint or a sleeve is crimped, and the electric hydraulic pliers are high-end tools. Due to the complex manufacturing process, constructors are not easy to master, construction defects often occur, and most of power failures are caused by the reasons. In order to reduce the construction defects, the industry is gradually referred to foreign methods to use some simple manual tools, such as cable shears, small electric band saws, manual strippers, electric hydraulic pliers, etc., which only slightly reduce the labor amount, and hardly have any improvement on key quality factors of cable pretreatment, such as the cutting depth and position precision control of a cable sheath, the stripping depth and position precision of a shielding layer, a semi-conductive layer and an insulating layer of a split-phase cable, the shape and surface quality of a cut section, etc., on the contrary, because the tools are generally heavier, the operation and adjustment still depend on the experience and hand feeling of constructors, the flexibility is poor, and the constructors are often reluctant to use the tools and continue to use the original tools for operation. Because no better method is available to ensure the construction quality of the cable joint, the only method in the industry at present is to train and examine the constructors repeatedly in technical grade, all the tools used in the training and the examination are the most original tools, the efficiency is low, and the process quality can not be effectively ensured all the time. Therefore, the quality of installation of the cable joint is just the most painful point in cable construction.
