Description:
Consisting of standardized, compact, internal arc-proof metal-enclosed modules (LSC2A-PI), equipped with SF6-insulated load-break switches and vacuum circuit breakers. Compartment modulation allows for complex configurations.

Each module is equipped with interlocking mechanisms (Kirk Lock) and mimic diagrams, ensuring maximum reliability and safety during cubicle maintenance and operation. The internal arc-resistant design allows these cubicles to be used even in extreme conditions.

Developed for use in medium-voltage secondary distribution systems. They can also be used to protect and power power lines in transformer substations, cogeneration plants, and photovoltaic plants, among others.
