Metal Clad Withdrawable Switchgear – Reliable Power Distribution Solutions

Safety and dependability are musts when you're in charge of important power facilities. With current values of up to 4000A, our Metal Clad Withdrawable Switchgear works well in middle voltage systems ranging from 4.16kV to 38kV, meeting the needs of large businesses. Each unit was made by Xuzhou Tuojie International Trade Co., Ltd. and has our unique "Five Preventions" mechanical interlocking system and a compartmentalized design that keeps problems separate and keeps your staff safe. We make switchgear that meets the standards set by IEEE C37.20.2 and IEC 62271-200. We have a technical team of 15 top engineers and more than 120 sets of modern production equipment. Our quality management follows ISO9001 rules, which makes sure that there are no mistakes at any stage of production.

What Makes Our Switchgear Different?

You should have tools that work when you need them the most. This hardware stands out because it solves the most important problems you face every day.

Withdrawable Design for Zero Downtime

You can't stop what you're doing for repair. So, we put circuit breakers on precision wheels that you can safely take off without turning off the power to the whole system. You can fix individual parts while keeping power going to important loads. This means that planned repair takes place when you want it to, not when the system does.

Compartmentalized Protection

Every panel is made with safety in mind, not just as an aside. We put grounded metal walls between functional parts to make four different rooms for cables, control equipment, circuit breakers, and busbars. If there is a fault in one area, it stays there. Your system keeps going and your employees are safe.

Advanced Interlocking Systems

Human mistake leads to expensive shutdowns. Our full range of mechanical interlocking stops unsafe processes instantly. You can't pull out a breaker by mistake when it's loaded or close it when there's a fault. You are protected in more than one way by these physical safeguards, which work even if the electrical controls stop working.

Technical Specifications You Can Trust

Where Your Investment Pays Off

Industrial Manufacturing Plants

Your factories are always making things. One hour of downtime costs a lot of money. Our switchgear has been put in places like the GCL Photovoltaic Industrial Park and the upgraded factories of XCMG Group. Because it's retractable, the design lets your team do repair during scheduled shifts instead of during emergency shutdowns. Our strong construction keeps working year after year in places like steel mills and chemical plants where corrosive air makes equipment last less long.

Mission-Critical Facilities

Hospitals, computer centres, and banks need to be up 99.99% of the time. Our Metal Clad Withdrawable Switchgear gives these places the redundancy and quick problem separation they need. Our two-circuit systems are used by both the Xuzhou Rail Transit Network Control Centre and the Xuzhou New Health Hospital Phase I. When time is of the essence, our arc-resistant design stops failures that could put whole processes at risk.

Commercial Buildings and Infrastructure

We power places where people live and work, like the Xinhuai Central Complex and the Huaihai Xintiandi developments. The easier repair procedures are appreciated by the people who run your buildings. Building codes require strict safety measures. Our dead-front construction hides any live parts that might be visible, and automatic shuttering systems keep bus links safe when the breaker is pulled.

Utility Distribution Networks

Power companies need tools that can last for decades and work in weather and very cold or very hot conditions. We've helped with city projects like the Xuzhou High-speed Railway East Station. The equipment can handle being loaded with ice, sprayed with cold water, and going through changes in temperature, and it also lets parts be replaced quickly during emergencies.

FAQ

Q: What exactly is product?

It's medium voltage distribution equipment (1kV to 38kV) where circuit breakers mount on movable carriages inside metal-enclosed compartments. You can safely remove and insert components for maintenance while adjacent sections remain energized. This design eliminates arc flash exposure during service operations and enables component replacement without system-wide shutdowns.

Q: How does the withdrawable mechanism improve safety?

The mechanism operates on precision-guided rails with positive mechanical interlocks. You physically cannot perform unsafe operations—the system prevents breaker withdrawal under load, closing onto faulted circuits, or accessing energized compartments. Even if electrical controls malfunction, mechanical safeguards remain active.

Q: What maintenance advantages should I expect?

You'll reduce downtime significantly. Circuit breakers withdraw completely from cabinets for service. Your team can perform maintenance during scheduled outages without disturbing busbars or adjacent feeders. This modular approach means faster repairs, simpler troubleshooting, and lower lifecycle costs.

Q: Which certifications do your products hold?

All our switchgear complies with IEEE C37.20.2 and IEC 62271-200 standards. We maintain ISO9001, ISO14001, and OHSAS 45001 certifications. Our low-voltage products carry National CCC Mandatory Certification. We can provide documentation for seismic qualification (IEEE 693) and arc-resistant testing (IEEE C37.20.7) upon request.

Q: Can this equipment handle harsh environments?

Absolutely. We've designed for operation from -40°C to +55°C with humidity up to 95%. Our installations perform reliably in corrosive atmospheres, extreme weather conditions, and high-altitude locations. The IP54-rated enclosures provide dust and moisture protection while maintaining arc fault containment capabilities.

Q: What's your typical lead time and support process?

Lead times vary based on customization requirements, typically ranging from 8-12 weeks. Our team assists with specification development, factory testing coordination, and installation support. We maintain comprehensive documentation and provide technical training for your maintenance personnel.

Q: How does this compare to air-insulated alternatives?

Our vacuum and SF6 insulation technologies offer superior dielectric performance in smaller footprints. You'll get higher breaking capacities and better protection against environmental contamination. The sealed design reduces maintenance requirements compared to traditional air-insulated equipment exposed to dust and moisture.
