Tips: How to maintain Isolator switch?
The function of the isolating switch is very important. If there is a failure, it will bring great inconvenience to daily work and production, so daily maintenance work needs to be done. For example, you should always check the surface of the equipment to see if there are any weak or damaged parts. Sometimes the isolation switch needs to be used in a special environment, which may cause deformation and oxidation. If the situation is serious, it needs to be replaced in time. Heating at the contact parts is also common, which is related to many reasons, and sometimes requires power outage maintenance.
