The product line includes many proven designs. From these established solutions, nVent can incorporate special requirements to satisfy each project's specific needs. Through this approach, each customer receives custom-built equipment satisfying their unique requirements. The diverse product scope features RTU/SCADA/PLC integrated designs and ranges from small junction skids to complex trailer-mounted substations with walk-in enclosures.
Rugged. Portable. Customized.
When providing switchgear for the mining industry, rugged and durable construction is paramount. Equipment must withstand extreme temperatures, frequent transport, and harsh conditions. In such environments, your project requires more than switchgear – it demands proven “mine-duty” engineering.
nVent builds modular equipment that utilizes heavy-duty materials and an all-welded design. This industry-leading construction process ensures that customers can count on a solution that will prove both durable and reliable throughout its service life.
Skid-mounted units are constructed with 11 Ga. reinforced enclosures featuring doors with stainless steel hinges. This all-welded assembly is mounted to a heavy-duty skid featuring 1/4" deck plates, 1.5" towing eyes, 1" thick wear plates on runners and noses, and heavy-duty beams and channels. For blast protection of the transformer, 3/8" top and side steel plates are available on request.
Certified Quality and Safety
nVent is an ISO-9001 certified company that combines proven electrical expertise with an unmatched focus on safety. Personnel are safeguarded by the implementation of high voltage signs and metal safety barriers, door interlocks, ground monitors, and the use of fluidized epoxy bus insulation tested for use at voltages up to 38 kV.
At the project site, a team of MSHA certified field service technicians work to ensure the highest standard of safety is maintained.
Single Point of Contact
A dedicated project engineer is assigned who serves as the customer's single point of contact throughout the duration of the project. This person is solely responsible for the successful execution of job requirements and all communication with the customer. Your project engineer handles all aspects of design and manufacture of the equipment.

Diagram Description
The primary visual depicts a large, orange, ruggedized enclosure mounted on a heavy-duty skid, connected to a grey electrical transformer unit. The enclosure features multiple access doors with visible stainless steel hinges. Prominent warning labels state "DANGER HIGH VOLTAGE 25,000 VOLTS" (also in Spanish: "PELIGRO ALTO VOLTAJE 25000 VOLTIOS"). Key construction highlights include an 11 Ga. reinforced enclosure, an enclosure fully welded to the base, 1" thick wear plates on runners and noses, 1.5" towing eyes, and 1/4" deck plates. The base design is engineered for load spreading. The transformer unit is equipped with SCADA Communication Capabilities, offering serial & Ethernet ports, and can accommodate transformer sizes up to 20 MVA.
