popular High Voltage Switchgear SF6 Maintenance unit

Ring Main Unit Switchgear does not experience arc flash. Therefore, this characteristic makes it safer than other switchgear that are prone to arc flash. In the ring main unit switchgear, the problem of arc flash is quenched by the insulating material, Sulphur hexafluoride (SF6) gas. This makes the system more reliable.

The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance.
