As a dedicated manufacturer with over a decade of experience in high-voltage electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to present the Schneider SM6 SF6 Gas-Insulated Switchgear Cabinet in the 630A, 12kV/24kV configuration, featuring DM1-A, IMC, and IMP functional units. This compact and reliable switchgear is designed to meet the rigorous demands of modern power distribution networks, offering exceptional safety, long service life, and minimal maintenance. Each cabinet undergoes comprehensive factory testing and comes with a standard warranty to ensure you receive a product that performs flawlessly from day one.
Our SM6 switchgear leverages the proven advantages of SF6 gas insulation, which provides excellent dielectric strength and arc-quenching properties in a sealed-for-life enclosure. This design eliminates the need for routine gas handling and significantly reduces the risk of internal faults. Whether you are upgrading an existing substation or building a new distribution system, the SM6 series delivers the performance and reliability you can trust.
Key Features & Technical Specifications
- SF6 Gas Insulation – Sealed pressure system (0.3 bar relative) ensures consistent dielectric performance and no moisture ingress.
- Rated Voltage – 12 kV or 24 kV (optional configurations), meeting IEC 62271-200 standards.
- Rated Current – 630 A for main busbar and feeder circuits, with short-time withstand current up to 16 kA / 20 kA (1s).
- Modular Design – Includes DM1-A (disconnector/fuse combination), IMC (metering unit), and IMP (incoming/outgoing feeder) function modules for flexible system configuration.
- Factory Tested – Each cabinet undergoes routine tests including power-frequency voltage withstand, partial discharge measurement, gas leakage check, and mechanical operation tests.
- Warranty – Standard 12-month warranty against manufacturing defects, with extended warranty options available upon request.
- Compact Footprint – Width: 375 mm – 750 mm (depending on configuration), depth 940 mm, height 1600 mm; saves valuable floor space.
- Environmental Adaptability – Operating temperature range -25°C to +40°C, suitable for indoor installation in most climates.

Frequently Asked Questions (FAQ)
Q1: What is the difference between DM1-A, IMC, and IMP modules?
A: The DM1-A is a disconnector-fuse combination unit for protecting transformers or feeders. The IMC is a metering unit designed for voltage and current measurement. The IMP is an incoming/outgoing feeder unit for connecting busbars to cables. They can be combined in a single cabinet to meet your specific circuit requirements.
Q2: Is the SF6 gas environmentally friendly?
A: SF6 is a potent greenhouse gas, but the SM6 cabinet uses a sealed-for-life system with a very low leak rate (<0.5% per year). The gas volume per unit is small, and modern recycling practices are available. We comply with relevant environmental regulations and offer gas handling guidance.
Q3: What is the warranty period, and does it cover shipping damage?
A: The standard warranty is 12 months from the date of shipment, covering manufacturing defects in materials and workmanship. Shipping damage is not covered, but we package the cabinets carefully to minimize risk. Extended warranty options are available upon request.
Q4: Can the switchgear be customized for different voltage levels?
A: Yes, the SM6 cabinet can be configured for 12 kV or 24 kV rating. Please specify your required voltage level when ordering. Other customizations such as special coatings, cable entry positions, and additional accessory kits are also available.
Q5: What are the installation requirements?
A: The cabinet is designed for indoor installation on a level, vibration-free floor. It requires a minimum ambient temperature of -25°C and should be protected from excessive humidity. Detailed installation and commissioning instructions are provided with each unit.
Q6: Do you provide after-sales technical support?
A: Absolutely. Our technical team can assist with installation guidance, troubleshooting, and spare parts identification. We also offer on-site commissioning services (additional cost) for larger projects.
Q7: How long does delivery typically take?
A: Lead time depends on the quantity and configuration. For standard units, typical production time is 20–30 working days. After production, shipping to major ports takes 2–4 weeks. We can provide a more precise schedule after receiving your inquiry.
Q8: Is the SM6 switchgear compliant with international standards?
A: Yes, the SM6 series is designed in accordance with IEC 62271-200 and other relevant IEC standards. Our factory follows ISO9001 quality management system. Specific test certificates are available upon request.
