FAQs
Medium-Voltage Electrical Products

What Is Medium-Voltage Switchgear?

Medium-voltage switchgear is equipment used to control, protect, and isolate electrical circuits operating above low-voltage levels. It is commonly used in utilities, industrial plants, campuses, and data centers.

What Is the Difference Between Metal-Enclosed and Metal-Clad Switchgear?

Medium-voltage metal-enclosed switchgear houses switching devices in enclosed sections. Metal-clad switchgear uses segregated compartments and drawout breakers for added safety and maintainability.

Does MCG Manufacture Custom Medium-Voltage Switchgear?

Yes. MCG designs and manufactures custom medium voltage switchgear, paralleling gear, substations, and integrated power systems tailored to project needs.

Does MCG Provide Retrofit and Maintenance Services?

Yes. MCG provides inspections, testing, commissioning, modernization, breaker rebuilds, and emergency service support for medium-voltage systems.

How Does MCG Improve Time-to-Power?

MCG combines engineering, manufacturing, controls integration, testing, and field services under one partner to reduce handoffs, shorten schedules, and accelerate deployment.
