O.T.K - 36kV Automatic Recloser
Structure;
O.T.K recloser’s enclosure is made of fully welded SF6 insulated stainless steel, the enclosure is containing vacuum interrupters, control mechanism, currrent transformers and voltage sensors.
Mounting brackets for lightning arresters are located both sides of the body, the enclosure is earthed. Mechanism is located inside enclosure and its fully protected. The mounting bracket which is carrying the enclosue is designed to use the recloser in all pole types.
Recloser mechanism can be opened either electrically or manually, it can only be closed electrically. Position indicator of recloser can be easily seen from the ground. Recloser can be tripped from the ground by a hookstick.
