LYE101 JN15A-12/31.5 Indoor AC High Voltage Grounding Switch
Summary:
Grounding switches use resin insulators, on which live parts, made of silver-plated electrolytic copper (99.9%), are placed. The blades are directly connected to the drive shaft. Contact elements are overdimensioned according to the requirements in order to guarantee, together with a high contact pressure between blades and contacts, a reduced ohmic resistance at the contact surface and a minimum metal wear-off during the life of the grounding switch, with the necessary robustness to withstand thermal and mechanical stresses under short-circuit conditions.
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 IEC129 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.
