product use and characteristics
JW10series high voltage AC grounding switch is a three-phase AC power frequency50Hz/60HzOutdoor high-voltage transmission equipment is used to release the static charge of maintenance lines and equipment, and implement electrical safety grounding for high-voltage equipment such as busbars and circuit breakers after maintenance, so that there are obvious grounding opening and closing signs in the lines, so as to ensure the personal safety of maintenance personnel during power failure. It is usually used to ground the upper bus where a single-post vertical disconnect switch is used.
