JN15A-12/31.5 Indoor AC High Voltage Earthing Switch for KYN28
Summary:
JN15A-12/31.5 indoor AC high voltage grounding switches 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 equipment overhaul.
There shall have no conductive dust,no corrosive gasess,no severe vobaration and impact.no combustion and explosion on the site for switch operating.
Features:
JN15A-12/31.5 Indoor AC high voltage grounding switche 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.
Ambient Environment:
1.Altitude: less than 1000m
2.Ambient temperature: -10ºC to 40ºC
3.Earthquake intensity: no more than 8 degree
4.Pollution: II
5.Relative humidity: Daily average less than 95%.Monthly average less than 90%
