RSV 22 – Innovative, Quiet, Reliable

RSV 22 is a three-phase on-load tap-changer, one of the latest developments in the Voltap OLTCs manufactured by Elprom Heavy Industries. It expands upon the RS 21, a tried and tested single phase tap-changer in operation for more than 15 years in all major Korean cities. Designed by Elprom according to KEPCO specifications, RS 21 operates in SF6 insulated power transformers in the KEPCO grid.

The SF6 gas is well known for its dielectric properties and is widely used in underground substations, densely populated cities, mission critical substations, and offshore substations minimizing the risk of fire, explosions, and contaminating leaks, which the traditional oil-insulated gear is prone to. Gas-insulated electrical gear is also more resistant to the effect of pollution and climate, as well as being more reliable in long term operation because of its controlled operating environment.

RSV 22 also ensures minimal long term maintenance requirements and uninterrupted power supply to all customers of the KEPCO grid.

Come and visit us at Seoul International Electric Fair & Power Generation Korea from 03.04.2024 – 05.04.2024 at booth: L402, COEX Hall A, B and learn more about the key parameters and applications of RSV 22.
