  • Product Description

SPE101 JN15A-12/31.5 Indoor AC high voltage grounding switches

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

electrical 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.

feature

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.
