Description
JN15-12/31.5 Series of Indoor High Voltage Earthing Switch
 
1.General description
JN15-12/31.5 series indoor high voltage earthing switch (hereinafter referred to as earthing switch)  is a new type  earthing switch that designed and developed by our company according to market requirements.  It can be used for 3~12kV three phase AC 50 (60) Hz electrical system and match all kinds of high voltage switchgear,  as well as for maintenance of high voltage electrical equipment.

The earthing switch with simple structure and good dynamic and thermal stability is light and convenient for using and installation.
 It is a good replacement of JN4-10 type earthing switch.
 

2. Main technical parameters
2.1 Rated operational voltage  12kV
2.2 Rated short time withstand current (4s) 31.5kA
2.3 Rated peak withstand current 80kA
2.4 Short-circuit making current 80kA
2.5 Insulation level: full-wave impulse voltage 75kV
  Main circuit power frequency withstand voltage (1min)    42kV
2.6 After opening, the distance between gaps is no less than  125mm


3. Applying ambient conditions
3.1 Applying to below ambient conditions
3.1.1 The height above sea level: ≤1000m;
3.1.2 Ambient temperature: -10ºC~+40ºC;
3.1.3 The daily average humidity should be no more than 95%; the average humidity of a month should be no more than 90%;
3.1.4 Earthquake intensity: not exceed 8 degrees.
3.2 It should not apply to below ambient conditions:
3.2.1 The ambient conditions have gas, vapour, chemical hazard, mist, dust, filth and explosive and erosive substance that     may seriously impact the insulating and electric conductive property;
3.2.2 The ambient conditions are shocked frequently and drastically.


4. Ordering instruction
The earthing switch can apply for wide range. Please advise product's type and model, assembled position of operating crankarm (left of right);  if you need electrical indicator device or not; or if you have any special requirements, please discuss with the manufacturer before you place 
an order.
