Mvnex armored metal enclosed switchgearProduct Introduction
In 1958, Schneider Electric produced its first medium voltage switchgear. For more than five years, Schneider Electric has always adhered to the concept of meeting customer needs, and has been committed to providing protection, monitoring, and control solutions for medium voltage distribution in the public distribution, industrial, and construction fields.
MVnex is a type of enclosed switchgear that applies to high-voltage/medium voltage and medium/medium voltage substations. The switchgear is a movable and armored type. The design of MVnex fully considers the requirements of using all three; Reliable power supply continuity; Easy installation, operation, and maintenance; The safety of operators.
