JN15-24 Liyond Manufacture Indoor AC High Voltage 24kV Ground Switch High Speed Earth Knife
JN15-24/31.5 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 24kV 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 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.
