HT Panel

HT Panel

Medium voltage (MV) electrical distribution solution with AIS insulation technology and vacuum quenching apparatus. Safe and reliable in all environments, it is fully compliant with IEC 62271-200 including loss of service continuity LSC2-B and metallic partition (PM).
Our MV Panel is a flexible product, simple, modular and functional. Indeed, it is aimed at the requirements of the end user and adapts to the final needs through tailored solutions and customizations made by RST.
It is also switchgear ready for smart grids directly integrating our simple or advanced protections and solutions , control and monitoring for superior reliability and mastership of energy efficiency.
