  • SF6 gas in medium-voltage switchgear | TD Guardian Articles

    SF6 has excellent dielectric properties, and is well suited for use in interrupting devices for relatively low switching ratings, such as for load interrupter switches used in the SIMOSEC switchgear line. Use of SF6 reduces the space requirements for the switchgear, isolates the switching elements from environmental contamination, and allows significant reduction of maintenance.

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.
