Mechanical Indoor AC HV Earthing Switch For Power System JN15-12/T40
JN15A-12/31.5 indoor AC high voltage earthing switch is an advanced level product with high-tech parameters performance. After comprehensive evaluation,it conforms to GB1985 and IEC62271 standard ,applies to power system of 3-12kV and three-phase AC 50Hz.It owns short-circuit making capacity to protect other electric equipment not being damaged.Can be used with various high voltage switchgear,also play a protective role in the high-voltage electrical equipment overhaul.
Earthing switch, a mechanical switch used in the grounding part of a circuit, belongs to the isolation switch category.
It can carry current under abnormal conditions(such as short circuit current) for a certain period of time, but it is not required to carry current under normal circuit conditions.
Note: Ground switches may have short circuit connection capacity.
To ground high-voltage equipment and lines during maintenance in place of portable ground lines to protect personal safety .
