Main benefits
Sécheron possesses years of experience developing and manufacturing products and solutions for railway DC traction power substations. Our know-how encompasses the integration of SW-type offload disconnect switches.
Our disconnect switch panels cover all disconnector cubicle supply needs and are available for indoor and outdoor installations. Our virtually unlimited range of configurations address the vast majority of needs.
Our indoor incoming switches isolate the high-voltage output of the rectifier groups from the feeder DC distribution bus. Our indoor negative switches isolate the negative pole of the rectifier and can contain one or multiple single pole disconnectors. Our indoor coupling switch subdivides the main busbar into separate sections.
Our outdoor and wayside switches include feeder isolating switches and over-area, intersection isolating switches.
