FYN33 Type Four-Position Oil Immersed Load Break Switch

FYN33-38 four position LBS

Load break switch is a manually operated, two posiiton, 4 position, load make or break, oil immersed, single phase or three phase rotary switch.

This type swith is apply to the composite transformers with 50Hz AC and rated voltage of 12kV and 35kV. It is a nice and small load switch designed to meet the challenge of continually raising the load capacity of power net while the composite transformers usually have a very limited internal space. It uses the transformer oil as the media of insulation and that for preventing the electric arc. It uses a mechanical spring for reserving energy. Three phase linkage is available with it. Also it can promptly and accurately turn on or cut off the electric current. This switch can be applicable to any power distribution system with 12kV and 35kV and double power supply lines.
