Product descriptions from the supplier
Description
The quality of Square D Masterclad™ Medium Voltage Metal-Clad Switchgear stems from a design and manufacturing process that focuses on long-term switchgear performance with the highest degree of reliability. Reliable performance and safety are enhanced by the rugged construction of Masterclad switchgear. The switchgear consists of individually grounded, compartmentalized steel structures to protect operating personnel and equipment.
Masterclad switchgear components include available state-of-the-art electronics like ION power quality monitoring and EASERGY protective relays, EcoStruxure™, integrated racking, and automatic throwover systems.
Standardization of the design incorporates a series of basic modular units, control packages, and instrumentation. For most switchgear ratings, circuit configurations, and functions, one basic size unit is used. These features provide application flexibility, versatility, and efficiency, reducing lead time and engineering time spent on planning and laying out the switchgear.

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
