The RSV12 on-load tap changer is a variant of the RS12 design with vacuum interrupters. The RSV12 is the best solution for small to medium sized power transformers in grid or industry applications. The compact and light design helps to reduce the transformers size and weight while the vacuum technology guarantees long operational life and low maintenance requirements. The single compartment allows for easier and lower cost maintenance.
The RSV12 is designed and manufactured according to the requirements of the International Standard IEC 60214-1.
