Product Description
1. General
Type SYTZZ-33/200-17 is an in-tank mounting on-load tap changer, it applies resistance transition Principle. The OLTC is a selector switch type with an oil compartment to separate OLTC oil from transformer oil . there is a motor drive mechanism in the top of OLTC and the motor is controlled by Yk-2 controller . The OLTC has the advantages of simple structure and easy maintenance.
