Introduction: Why Your Business Needs a Custom Fit
When you search for custom medium voltage switchgear, you're not just browsing specs. You're tackling a unique challenge.
Perhaps standard equipment doesn't fit your installation site. Or maybe your operating environment is simply too harsh.
You need a solution that's tailored, robust, and safe. And you likely need it quickly.
I've been in your position. I’m an electrical engineer at Wei Shoe Elec. I’ve designed hundreds of medium voltage switchgear systems.
From coastal wind farms in Denmark to underground substations in Toronto, each project was unique. Yet, they all proved one truth.
Custom switchgear isn't a luxury. It's essential when safety, reliability, and compliance are non-negotiable.
Why Standard Switchgear Falls Short
Limited Space, Harsh Conditions, and Evolving Needs
Off-the-shelf switchgear often seems convenient. But here's what commonly goes wrong:
Size Mismatch: Standard cabinets are often too bulky. They don't fit compact substations or retrofits.
Environmental Stress: Salt air, high humidity, or excessive dust can rapidly degrade conventional equipment.
Functional Gaps: You need specific add-ons. Think arc protection, SCADA integration, or specialized relays. Standard units typically don't include these.
📌 Key takeaway: Custom solutions fit your site, climate, and needs perfectly.
What Exactly Is Custom Medium Voltage Switchgear?
It's far more than just "modified gear." It's a system meticulously crafted for your needs:
Designed for your voltage class: Typically ranging from 3.3kV to 36kV.
Engineered for your environment: Featuring IP54/IP65 enclosures or robust corrosion-proof designs.
Built with your operations in mind: Incorporating custom busbar layouts, precision metering, and advanced protection schemes.
For instance, we worked with an oilfield plant in Texas. They needed arc-resistant gear due to constant power surges.
We added vacuum breakers, special relay logic, and copper busbars. These busbars have a flame-retardant coating. Everything was unified into a single, high-performance unit.

Understanding Key Technologies in MV Switchgear
To truly appreciate custom solutions, it helps to know the core technologies.
Gas Insulated Switchgear (GIS)
GIS uses sulfur hexafluoride (SF6) gas for insulation. This makes it incredibly compact.
It's ideal for urban areas or offshore platforms where space is limited. GIS designs offer enhanced safety and minimal maintenance.
Vacuum Circuit Breakers
These breakers use a vacuum interrupter to quench arcs. They offer excellent performance.
They are virtually maintenance-free and have a long lifespan. Vacuum technology is a cornerstone of modern, reliable switchgear.
Arc-Flash Protection
This critical safety feature detects an arc fault. It rapidly trips the upstream breaker.
This minimizes damage and significantly reduces injury risk. It's vital for personnel safety.
SCADA Integration
SCADA (Supervisory Control and Data Acquisition) allows remote monitoring and control. You can manage your power system from anywhere.
It provides real-time data, enhances operational efficiency, and enables predictive maintenance.
