Customized Low Voltage Power Distribution Switchgear Cabinet IEC439-1 GB7251.1 Standard

Our Custom Low Voltage (LV) Switchgear Cabinets are engineered to provide precise, reliable, and scalable power distribution for complex industrial networks. Recognizing that no two facilities are the same, we offer a "Design-to-Spec" service that allows you to customize every aspect of the switchgear—from the physical footprint and ingress protection (IP rating) to the specific brands of circuit breakers and smart monitoring tools.

Whether you require a Fixed-Type (GGD) or Withdrawable (GCK/GCS/MNS) configuration, our custom cabinets are built to handle AC 50/60Hz systems with rated currents up to 4000A. These units serve as the primary control hub for industrial plants, infrastructure projects, and commercial grids, ensuring maximum uptime and optimized energy management.

• Fully Bespoke Engineering: We build according to your Single-Line Diagram (SLD). Customize the busbar capacity, cable entry orientation (Top/Bottom), and internal partitioning (Form 1 to Form 4b) to meet site-specific safety and space needs.

• Component Brand Flexibility: Unlike proprietary manufacturers, we allow you to specify your preferred switchgear components, including ABB, Schneider, Siemens, Eaton, or CHINT, ensuring compatibility with your existing spare parts inventory.

• Rugged Modular Framework: Built using high-precision CNC-machined 8MF or C-type profiles with Aluminum-Zinc (Al-Zn) coating or cold-rolled steel, providing superior structural integrity and a service life exceeding 20 years.

• Advanced Smart Integration: Optional integration of IoT-enabled smart meters, power quality analyzers, and remote communication modules (RS485, Modbus, Ethernet) for real-time SCADA monitoring.

• Superior Environmental Protection: Choose from indoor IP30/40 ratings or heavy-duty outdoor IP55/IP65 enclosures with specialized UV-resistant coatings and thermal management systems.

1. Industrial Manufacturing: Customized power centers for automotive, chemical, and textile production lines.

2. Data Centers & Telecom: High-reliability distribution with redundant ATS (Automatic Transfer Switch) integration.

3. Mining & Extraction: Heavy-duty, vibration-resistant cabinets designed for harsh, dusty, or corrosive environments.

4. Infrastructure & Utilities: Bespoke solutions for wastewater treatment plants, airports, and metropolitan transit grids.

• Rapid Prototyping & CAD Support: Our engineering team provides detailed 2D/3D CAD drawings for approval before production begins, ensuring the unit fits your physical space perfectly.

• Optimal Heat Dissipation: Every custom design undergoes thermal simulation to ensure that even high-density breaker arrangements remain within safe operating temperatures.

• Safety First Interlocks: All custom units feature comprehensive mechanical and electrical interlocks to prevent operator error and ensure the highest level of workplace safety.

• Factory Acceptance Testing (FAT): Every custom cabinet undergoes rigorous testing, including insulation resistance, power frequency withstand, and functional sequence testing, before leaving our facility.

Q: Can you manufacture a cabinet to fit a very narrow electrical room?

A: Yes. One of our core strengths is "Space-Optimization." We can customize the height, width, and depth of the enclosure and utilize back-to-back or vertical busbar arrangements to save floor space.

Q: Do you support Form 4b internal separation?

A: Absolutely. We can provide all levels of internal partitioning (Form 1, 2, 3, 4a, 4b) to ensure that maintenance can be performed on one circuit while others remain live and safe.

Q: What is the typical lead time for a custom switchgear order?

A: Depending on component availability and complexity, standard custom orders ship within 4 to 8 weeks following final design approval.

GCS low voltage withdrawable switchgear assembly(hereinafter referred to as device)is the former state Ministry of Machinery, the Ministry of Electric power joint design group according to the industry authorities, the majority of power users and design units developed in line with the national conditions, with high technical performance indicators, can adapt to the development of the power market needs and can compete with the existing introduced products. In July 1996, the device passed the appraisal jointly presided over by two departments in Shanghai, and received the attention and affirmation of the production and manufacturing units and power use departments.

The device is suitable for power plant, petroleum, chemical, metallurgy, textile, high-rise building and other industries of power distribution system. In large power plants, petrochemical systems and other places with a high degree of automation, requiring computer interface, as a three-phase AC 50(60)Hz, rated working voltage 380V, rated current 4000A and below the distribution, centralized control of the motor, reactive power compensation of the low-voltage distribution device.

The device conforms to IEC439-1 and GB7251.1 standards.
