Metal Clad Withdrawable Medium Voltage Switchgear

Metal Clad Withdrawable Medium Voltage Switchgear

When your facility demands uninterrupted power distribution with maximum safety, our Metal Clad Withdrawable Medium Voltage Switchgear delivers proven performance. At Xuzhou Tuojie International Trade Co., Ltd., we bring over 20 years of manufacturing excellence supported by 15 senior engineers and 18 patents. Within our switchgear, there are fully enclosed metal rooms with 12kV, 24kV, and 40.5kV circuit breaker elements that can be totally removed. With protection levels of IP54 and current rates of up to 4000A, this equipment provides better arc control and worker safety. From inspecting the raw materials to delivering the finished product, our factory uses more than 120 sets of high-tech equipment and strictly adheres to ISO9001 quality standards at all stages of production.

What Makes Our Switchgear Stand Out?

You get more than just equipment when you choose our solution. You receive a system designed around your operational needs.

Our metal clad design provides complete compartmentalization. The bus, breaker, and cable sections remain completely isolated from each other. This separation means a fault in one area won't compromise adjacent compartments.

The withdrawable trolley mechanism represents the core of our engineering philosophy. Your maintenance team can fully extract circuit breakers without de-energizing the entire system. This feature drastically reduces downtime during scheduled maintenance or emergency repairs.

We've equipped every unit with comprehensive "Five Preventions" mechanical interlocking. This system prevents operational errors that could endanger personnel or damage equipment. Your operators can work confidently knowing the switchgear won't allow unsafe operations.

Technical Specifications You Can Rely On

Your facility benefits from dead-front construction that eliminates exposed live parts entirely. Automatic shuttering systems protect bus connections when the circuit breaker withdraws. Visual position indicators provide instant confirmation of breaker status.

Core Advantages That Protect Your Investment

Superior Safety Performance

Our product employs multiple safety layers. The metal-clad construction contains arc faults within designated compartments. Should an electrical fault occur, the energy releases safely without endangering personnel or adjacent equipment.

The complete segregation of components means you can maintain one section while others remain energized. This capability proves invaluable in mission-critical facilities.

Maintenance Without Disruption

Traditional switchgear requires full system shutdowns for maintenance. Our withdrawable design changes that equation completely.

Your technicians can remove circuit breaker assemblies on precision-guided rails. The mechanical interlocks prevent unsafe extraction attempts. Once withdrawn, maintenance proceeds while the busbar remains undisturbed.

This approach significantly reduces your operational costs. You maintain equipment during scheduled outages rather than creating emergency shutdowns.

Built for Intelligence Integration

Modern facilities need smart monitoring capabilities. Our switchgear platform accommodates sensors and monitoring devices seamlessly. You can upgrade to advanced functions like "one-touch sequential control" as your requirements evolve.

The compartmentalized design provides ideal mounting locations for temperature sensors, partial discharge detectors, and current transformers.

Where This Equipment Excels?

Industrial Manufacturing Environments

Chemical plants, steel mills, and automotive facilities operate continuously. Production shutdowns cost thousands per hour. Our withdrawable switchgear enables maintenance during planned outages rather than forcing unexpected stops.

The robust construction withstands corrosive atmospheres and mechanical stress. We've proven performance in temperatures exceeding 40°C with contaminated air conditions.

Power Generation and Distribution

Utility substations require equipment that performs across decades. Our switchgear withstands extreme weather, seismic events, and daily load cycling.

The withdrawable features enable rapid component replacement during storm recovery operations. Your crews can restore service faster when every minute counts.

Mission-Critical Infrastructure

Data centers, hospitals, and financial institutions cannot tolerate power disruptions. Our Metal Clad Withdrawable Medium Voltage Switchgear provides 99.99% reliability through redundant protection systems.

Arc fault containment prevents cascading failures. If one circuit experiences problems, the metal compartments ensure adjacent systems continue operating normally.

Proven Performance Across Major Projects

We've delivered reliable solutions across hundreds of installations:

Our equipment powers the Xuzhou Rail Transit Network Control Center, where dual-circuit configurations ensure absolute safety. The Xuzhou High-speed Railway East Station depends on our switchgear for uninterrupted passenger services.

Industrial clients including XCMG Group factory upgrades and GCL Photovoltaic Industrial Park trust our technology. These projects were completed ahead of schedule while maintaining stringent quality standards.

Commercial developments like Xinhuai Central Complex and Huaihai Xintiandi benefit from our tailored solutions. The Tianyu Yayuan project achieved top quality assessment results using our equipment.

Quality You Can Verify

Every unit undergoes comprehensive testing before leaving our facility. Our quality inspection laboratory verifies performance against international standards.

We maintain ISO 9001, ISO 14001, and OHSAS 45001 certifications. All products carry National CCC Mandatory Certification.

Our "zero defects" philosophy extends through every production stage. Raw materials undergo incoming inspection. Production processes follow strict monitoring protocols. Finished products receive complete functional testing.

You won't find unqualified equipment leaving our factory. We've built our reputation on delivering exactly what we promise.

FAQ

Q: How often should I schedule maintenance inspections?

We recommend annual inspections with detailed maintenance every 3-5 years. Operating conditions in your facility may adjust this schedule. Required tests include contact resistance measurement, insulation resistance testing, and timing verification for opening and closing operations.

Q: Can I withdraw circuit breakers during emergency situations?

Yes, but you must follow specific safety procedures. Verify the circuit breaker is open using visual indicators. Confirm absence of voltage with approved testing equipment. Engage mechanical interlocks and ensure proper grounding connections. Emergency withdrawal requires two qualified personnel following arc flash protection requirements.

Q: What environmental factors might affect performance?

Temperature cycling causes expansion and contraction that impacts alignment tolerances. Humidity and contamination can affect contact surfaces. Regular lubrication using our specified compounds prevents degradation. Environmental sealing inspection maintains long-term reliability.

Q: How do I verify the equipment is installed correctly?

Perform visual inspection of enclosure welds and gasket seals. Verify pressure relief vent operation. Confirm arc detection system functionality. Review factory test certificates showing successful arc fault testing at rated parameters.

Q: What insertion force is normal for the withdrawable mechanism?

Normal insertion force should not exceed 400N (90 lbs) for manual operation. Higher forces indicate potential misalignment, contamination, or mechanical wear requiring immediate investigation.
