Most of the old substations and industries applications use old conventional type of Metal Clad Switchgears, Protection Relays and Circuit breakers.

Maintenance of these devices is time consuming and costly and spare parts are unlikely to remain available in the long term.

In order to meet our customer requirements with high quality, uninterrupted power supply and less cost, SEI takes the lead in this sector by retrofit the old systems with several solutions:

Upgrading MV switchgear systems by conversion or extension; as customer needs.
Replace the old oil circuit breaker with withdrawable vacuum one.
Develop the old protection systems by using modern protection relays.
With RETROFIT you can prolong the life of your switchgear, reduce maintenance costs, safety and simplicity of operation.
