Many activities for contracting, repairing, and testing electric power facilities
In China, those engaged in contracting, repairing, and testing electric power facilities shall obtain a license in accordance with the provisions of the "Measures for the Administration of Licenses for Contracting (Repairing, Testing) Electric Power Facilities". Unless otherwise stipulated by the State Electricity Regulatory Commission, no unit or individual may engage in contracting, repairing, or testing electric power facilities without obtaining a license. The license for contracting (repairing, testing) electric power facilities is a qualification certificate issued by the State Electricity Regulatory Commission to enterprises that can perform installation of new equipment, equipment maintenance and care, and preventive testing of equipment. Units that have obtained the license carry out activities in accordance with the law and are protected by law.
The grades of licenses for contracting (repairing, testing) electric power facilities are divided into Level 1, Level 2, Level 3, Level 4, and Level 5. Only those who have obtained qualifications at each level can engage in contracting, repairing, and testing electric power facilities at that level.
Enterprises applying for the qualification of contracting (repairing, testing) electric power facilities license must meet certain conditions, such as registered capital, equipment requirements, personnel requirements, technical requirements, etc. Among them, the difficulties and pain points for enterprises applying for the qualification license for the first time are:
1. For the first application for the contracting (repairing, testing) electric power facilities license, purchasing electric power test equipment and tools requires a large investment;
2. The electric power test equipment and tools specified in the contracting (repairing, testing) electric power facilities license are numerous, with many technical requirements, making it difficult to guarantee product quality and after-sales service;
3. Due to the turnover of electric power testing personnel, there are difficulties in training personnel to skillfully use electric power test equipment.
Our company, in order to solve customers' urgent needs, provides one-stop services for the industry's contracting (repairing, testing) electric power qualification.
One-stop services for electric power qualification include: agency for contracting (repairing, testing) qualification, technical consultation for contracting (repairing, testing) qualification, supply of electric power test equipment for contracting (repairing, testing), upgrading of electric power test equipment for contracting (repairing, testing), leasing of electric power test equipment for contracting (repairing, testing), and training for electric power testing for contracting (repairing, testing), and other full services.
