Welcome to Jinhua Dika Electrical Equipment Co., Ltd., a professional manufacturer with over 11 years of expertise in power distribution solutions. Our Schneider SM6 SF6 Gas-Insulated Switchgear Cabinet (rated 630A, 12kV/24kV) integrates advanced DM1-A IMC and IMP protection functions, delivering exceptional reliability and safety for medium-voltage distribution networks. Designed for compact substations, this switchgear combines the proven Schneider SM6 platform with our manufacturing precision, ensuring seamless integration and long service life.
The SM6 range is a globally recognized modular ring main unit (RMU) that uses SF6 gas as the insulating and arc-quenching medium, offering maintenance-free operation and high resistance to harsh environments. Each cabinet is factory-assembled and tested to meet rigorous quality standards, supporting both 12kV and 24kV systems with a rated current of 630A. The DM1-A IMC (integrated monitoring and control) and IMP (insulation monitoring protection) features provide real-time status feedback and enhanced fault protection, reducing downtime and operational risks.
Key Features & Technical Specifications

Frequently Asked Questions
-
Q1: What is the difference between 12kV and 24kV versions?
A: The same SM6 cabinet can be ordered with 12kV or 24kV rated voltage. The internal SF6 gas pressure and bushing design are adapted accordingly. Please specify your required voltage when ordering. -
Q2: Does the DM1-A IMC protection include remote communication?
A: Yes, the DM1-A IMC supports standard Modbus RTU protocol for integration with SCADA systems. Optional Ethernet communication is available upon request. -
Q3: Is the SF6 gas environmentally friendly?
A: SF6 is a potent greenhouse gas, but our switchgear uses a sealed-for-life system with -
Q4: Can you customize the cabinet color or dimensions?
A: Cabinet colors (e.g., RAL 7035 or custom) and minor dimensional modifications are customizable for large orders. Please consult our sales team for feasibility. -
Q5: What certifications do you hold?
A: Our factory is certified under ISO9001, ISO14000, OHSAS18001, and other management systems. The SM6 switchgear itself is designed to IEC standards and type-tested per relevant IEC publications. Specific certificates can be provided per request. -
Q6: What is the typical delivery time?
A: For standard configurations, delivery is 4-6 weeks after order confirmation. For customized units, lead time is 8-10 weeks, depending on complexity. -
Q7: How do I perform maintenance on the SF6 tank?
A: The SF6 gas tank is sealed for life and requires no routine maintenance. Only periodic visual inspection and low-pressure monitoring via the DM1-A IMC are needed. Refilling is not necessary under normal conditions. -
Q8: Can this switchgear be used outdoors?
A: The SM6 cabinet is designed for indoor installation (IP4X). For outdoor use, a weatherproof kiosk or enclosure is required. We can provide a matching outdoor housing upon request.
