How to train cable line operators?

The operation of cable line is a highly professional work. The technical training of AAAC Cable operators should focus on cultivating various basic skills. The learning contents mainly include:
1) basic knowledge of electrical theory;
2) structure and characteristics of power cable;
3) cable laying and manufacturing methods of joints and terminals;
4) understand the cable line design, power system operation diagram and assembly drawing of joint process;
5) performance, processing and storage methods of various common insulating materials;
6) high altitude operation skills on poles and towers;
7) cable test technology;
8) be familiar with safety and quality management procedures and systems (including urban construction, public utilities, transportation and other relevant regulations);
9) computer and other related skills.
in addition to the necessary classroom explanation and on-site practice, these basic skills should be carried out in combination with the on-site conditions. Cable line operators must be trained in the above basic skills, have certain on-site work experience, and then learn the professional knowledge of ACSR Cable operation in order to be competent for the operation of cable line.

Relevant training discussion in the three-year action plan for improving the professional level of high voltage cable 2019-2021:
3. The contradiction between the high requirements for the whole process control of cables and the low level of personnel and equipment is becoming increasingly prominent
With the rapid growth of equipment scale and assets, the business volume of operation and maintenance, maintenance and engineering cooperation of cables and channels is growing rapidly. In order to ensure high reliability power supply of urban power grid, the requirements for the whole process control of high-voltage cables are becoming higher and higher. However, some cable professionals have insufficient skills in inspection, test, maintenance and project acceptance, lack of civil engineering and other professionals, insufficient equipment allocation for test and detection, and there is still a gap with the actual work requirements. At the same time, the training of professionals is still lack of the support of practical training system, and the talent training mode needs to be improved.
