Product Description


JN15-40.5/31.5 HV Earthing Switch

IndoorHV Earthing Switch

Earthing switches with fault making capacity can be reliably closed against short-circuit currents, thus protecting the operator and switchgear in the cause of inadvertent operation. Naturally, operation behind a closed compartment door forms part of the overall cubicle safety.

Rated voltage (kV) 12 - 24Rated short-circuit closing capacity (kA) 63 - 110There are two forms of earthing switch: - independent earthing switches and - earthing switches with combined current transformers. The current transformers of the combined version form the mounting base for the earthing switch contacts thus reducing the space required in the cubicle.Every earthing switch is fitted with a spring operating device which makes the closing capacity independent of the operating speed. The control side of the earthing switch and direction of current can usually be chosen without limitations except for a few models with combined current transformers.

JN15-12/24/40.5 indoor HV earthing switch absorbs advanced new technics from domestic and aborb. It conforms to GB1985 AC HV disconnect switch and earth switch, relative standards IEC60129 and passes KEMA test. The apparatus applies to power system of rating below 12kV/24kV/40.5kV, and AC50/60Hz. It is suitable for various types HV switchgear for earthing protection. The holistic earthing switch consists of basis, supporting insulator, main axis, main blade, fast spring, fixed and moving contact. Additional electronic display is also available according to the user's requirement.
