Our Medium Voltage Metal Enclosed Switchgear performs at a business level when your building needs the highest level of electricity safety and dependability. Our KYN-type switchgear can handle voltages from 4.16kV to 38kV and currents from 600A to 4000A. It has improved compartmentalization and grounded metal panels that make sure there is full fault isolation. Our team of 15 top engineers and 18 patents backs up our strong equipment, which can interrupt up to 63kA and has an IP54 rating for security. Our switchgear has vacuum breakers placed on moveable trolleys, which makes servicing easy and keeps the system running. Each unit is made with more than 120 high-tech machines and is approved to ISO 9001 standards. From checking the raw materials to the final testing, there is strict quality control at every step.

Your electrical infrastructure deserves protection that goes beyond basic functionality. Our switchgear employs metal-clad construction with heavy-gauge steel enclosures, creating isolated compartments for busbars, circuit breakers, and control systems.
Why compartmentalization matters to you:
The withdrawable circuit breaker design allows you to roll the breaker completely out of the cabinet. You can perform inspections, testing, and repairs during scheduled outages without disrupting the main busbar system. This significantly reduces your operational downtime.

Manufacturing facilities require specialized approaches:

Q: What maintenance intervals should I expect for your switchgear?
A: Standard intervals include annual visual inspections and biennial electrical testing. Major inspections with breaker servicing occur every five years. However, your specific environment affects these schedules. Facilities with dust, moisture, or corrosive conditions may need more frequent attention. We recommend predictive maintenance using thermography and partial discharge monitoring to optimize schedules while preventing failures.
Q: How does your design protect against arc flash incidents?
A: Our metal-clad construction provides multiple protection layers. Grounded metal compartments contain fault arcs within affected sections. Pressure relief systems safely vent gases away from operating areas. The dead-front design eliminates exposed live parts during normal operation. Testing per IEEE C37.20.7 validates containment during internal arcing faults with pressures up to 8.4 times atmospheric.
Q: Can I expand capacity in the future without replacing the entire installation?
A: Absolutely. Our modular design uses standardized 30-inch sections. You can add circuit sections to existing lineups without system shutdown. The common busbar system extends across new sections. Standardized interfaces ensure compatibility with future additions. This expandability protects your initial investment while accommodating growth.
Q: What environmental conditions can your switchgear withstand?
A: Our equipment functions across -40°C to +55°C temperature ranges. IP54 protection rating guards against dust and water ingress. Corrosive atmosphere resistance comes from protective coatings and material selection. Seismic qualification per IEEE 693 ensures mechanical integrity during earthquakes. UV-resistant materials maintain performance in outdoor applications.
Q: How do you ensure product quality before shipment?
A: Every unit undergoes comprehensive factory acceptance testing. Dielectric strength testing validates insulation integrity. Short-circuit testing confirms interrupting capability. Temperature rise testing ensures connections remain within limits. Mechanical operation testing verifies breaker performance through thousands of cycles. We provide complete test reports with certification documentation for your records.
Q: Do you provide support for international projects with specific requirements?
A: Yes. Our engineering team customizes solutions for country-specific standards. We accommodate voltage variations, frequency differences, and environmental conditions worldwide. Complete documentation in English supports your project requirements. With 20+ years of experience, we understand diverse regulatory frameworks and provide appropriate certifications.
We go beyond equipment supply. Our services include:
Our business philosophy centers on "technology first, service paramount, and integrity fundamental." You receive responsive support throughout your project lifecycle.
