As a part of power lines, power cables are widely used because of their low failure probability, safety and reliability, and flexible outlets. However, once a fault occurs, the maintenance is more difficult, so special attention should be paid to the maintenance and testing.

1. Preparation before work

One type of work ticket should be used for power outage work, and the second type of work ticket should be used for work that does not require power outage. Before work, you should check the relevant path diagrams, arrangement diagrams, and concealed engineering drawings and materials. You must check the cable name and whether the identification plate is consistent with the work ticket. Work can only start after the safety measures are correct and reliable.

2. Matters needing attention at work

The cables to be repaired must be confirmed when working. The cables to be overhauled can be divided into two types:

The oil-immersed test transformer is a series of test transformers developed and produced according to the "Test Transformer" standard and relying on the research and development technology of the Wugao Institute after a lot of improvements on the basis of the original similar products. The product complies with DL/T848.2-2004 "High Voltage Test" Device Passing Technology-Part 2: Power Frequency High Voltage Test Device", a new product developed and produced. This series of products have the characteristics of small size, light weight, compact structure, complete functions, strong passability and convenient use. It is especially suitable for power systems, industrial and mining enterprises, scientific research departments, etc. to conduct insulation strength tests under power frequency or DC high voltage on various high voltage electrical equipment, electrical components, and insulating materials.
