LYE103 JN17-12/40 Indoor high voltage AC electrical earth switch

Summary

JN17-12/40 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.

Ambient condition:

Ambient temperature scope:form 12°C to40°C

Heavy cold zone:25°C allowed

Altitude not more than 1000m

Relative humidity:average everday not exceeding 95%

Monthly average not more than 80%

There shall have no conductive dust,no corrosive gasess,no severe vobaration and impact.no combustion and explosion on the site for switch operating.

feature

Indoor high voltage AC electrical earth 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.
