Product Description
The switch adopts new structure, new material, new technology, having the advantages of reasonable structure, good hand-feeling ,Flexible rotary, reach the position accurately etc, It is the improved product of the off-circuit tap changer in chinaat present, which applies to the three-phase oil-immersed electrical power transformer with the frequency of 50HZ,60HZ, the rated voltage of 10KV,35KV,the rated current of 63A,125A,250A. It can be directly fixed on the tank cover of the trans-former, operation under the off-circuit condition.
 
 
Off circuit tray form tap changer (WDP and WSP series)
 The specification of the product is rated voltage 35KV(highest voltage for equipment 40.5 kV) and below, rated current 400A and below.
 
WSP II₁,WSP III₁ series off-circuit tap changer (tray form)
This tap changer which is made of new structure,new material and new technology has the merits of reasonable in structure,handle freely, turning flexibly, locating exactly, good hermetically performance and small value of contact resistance ,it has become the new generation product in these days and has been certified by Ministry Department of China in December 1995. There are two sorts of products for this tap changer, it is suitable for oil-immersed three phase or single-phase power transformer with frequency 50Hz or 60Hz, highest voltage for equipment 12kV and 40.5kV and 72.5kV, rated current 63A, 125A, 250A and 400A. It can be fixed directly on transformer tank cover or tank wall, they must be working under non-energized condition.
 
The current of 63A tap changer is applicable to 5~8mm transformer cover (except single phase);
The current of 125A tap changer is applicable to 5-10mm transformer cover;
The current of 250A and 400A tap changers are applicable to 8-14mm transformer cover;
The moving contact's structure is clamping type or rolling type. The clamping type has no code number. If you need the rolling type, please illustrate in ordering.
We can manufacture the tap changer with raised highness beneath the cover in accordance with the customer's requirement; If you have other specific requirements please detail it in ordering.
