Welcome to Jinhua Dika Electrical Equipment Co., Ltd. – a professional manufacturer with 11–50 employees and an annual export value of US$1 million to US$1.5 million. As a trusted supplier in the electrical industry, we present the Schneider SM6 SF6 Gas-Insulated Switchgear Cabinet (630A, 12kV/24kV, DM1-A IMC IMP), designed specifically for primary distribution systems. This switchgear combines advanced SF6 gas insulation technology with a compact, sealed construction, ensuring high reliability, safety, and long service life in demanding environments. Whether for substations, industrial plants, or utility networks, our SM6 switchgear delivers consistent performance with minimal maintenance.
The SM6 switchgear is part of Schneider Electric’s renowned medium-voltage product range, and our factory in Jinhua, Zhejiang, China produces these units under strict quality control. With certifications including ISO9001, ISO14000, OHSAS18001 and more, we guarantee that every cabinet meets international standards. The DM1-A IMC IMP configuration features integrated metering, control, and protection functions, making it ideal for primary distribution networks where space and safety are priorities.
Key Features & Technical Specifications
- SF6 Gas Insulation: Sealed stainless steel tank filled with SF6 gas (0.4 bar relative pressure), ensuring arc-quenching properties and dielectric strength even in harsh conditions.
- Rated Parameters: 630A continuous current, 12kV/24kV rated voltage, 20kA/25kA short-circuit breaking capacity (depending on voltage level).
- DM1-A IMC IMP Configuration: Includes incoming/outgoing lines with integrated current transformers, voltage transformers, and protection relays. The IMC (Insulated Metal Clad) design ensures safe operation, while IMP (Integrated Measurement Protection) simplifies wiring and commissioning.
- Compact Footprint: Width of 900mm (for 12kV) or 1000mm (for 24kV), depth of 1500mm, and height of 1800mm – perfect for space-constrained substations.
- Safety Mechanisms: Pressure relief flap, gas density monitor, and interlocking systems prevent accidental access and overpressure.
- Environmental Resistance: Sealed unit protects against moisture, dust, and corrosive atmospheres; suitable for indoor and outdoor installations with optional weatherproof enclosure.
- Maintenance-Free Operation: Gas-sealed design eliminates the need for regular topping-up; typical service life exceeds 30 years with minimal inspection.
- Compliance and Testing: Type-tested according to IEC 62271-200 and IEC 60298 standards (available upon request).

Frequently Asked Questions (FAQ)
-
Q1: What is the typical lifespan of the SM6 switchgear cabinet?
A: Under normal operating conditions, the SM6 switchgear can exceed 30 years of service life due to the sealed SF6 gas insulation and robust construction. -
Q2: Is the SF6 gas harmful to the environment? Can it leak?
A: SF6 is a potent greenhouse gas, but our switchgear uses a sealed stainless steel tank with a gas density monitor. Leakage rate is less than 0.1% per year. We also offer leak detection and gas recycling as part of our service. Many regions allow its use under strict monitoring. -
Q3: What is the difference between DM1-A IMC and IMP configurations?
A: DM1-A is the main body type. IMC (Insulated Metal Clad) is an optional enclosure for added insulation, while IMP (Integrated Measurement Protection) includes built-in current/voltage transformers and a protection relay. The combination provides a complete switchgear unit for primary distribution. -
Q4: Can this switchgear be used for 24kV primary distribution?
A: Yes, the SM6 is rated for both 12kV and 24kV. When ordered for 24kV, the tank design and bushings are adjusted accordingly. The standard 630A current rating applies to both voltage levels. -
Q5: What maintenance is required?
A: The main advantage of SF6 gas-insulated switchgear is minimal maintenance. Periodic visual inspection, gas density checks (every 3-5 years), and functional tests of the operating mechanism are recommended. No need for routine refilling. -
Q6: Do you provide custom ratings (e.g., higher current or voltage)?
A: Yes, we offer customization options such as 1250A rated current or up to 36kV rated voltage. Please contact our sales team with your specific requirements. -
Q7: What are the shipping options and lead time?
A: We ship from Shanghai, Ningbo, Tianjin, or Guangzhou ports. Typical lead time for standard configurations is 25-35 working days. Express delivery available for urgent orders. -
Q8: Does the product come with a warranty?
A: Yes, we offer a standard 12-month warranty from delivery date. Extended warranty up to 36 months is optional. Our after-sales team provides remote troubleshooting and spare parts support.
