As a specialized manufacturer with over a decade of experience in electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to introduce our advanced Indoor SF6 Gas RMU featuring Glock Switches. Engineered for reliability and safety in demanding indoor environments, this unit combines the superior insulation properties of SF6 gas with a robust, corrosion-proof, and IP67 waterproof enclosure. It is designed to provide a compact, maintenance-friendly, and highly secure solution for medium voltage power distribution networks, ensuring uninterrupted operation even in challenging conditions.
This Indoor SF6 Gas RMU is built to meet the rigorous demands of modern power distribution. Its core advantages stem from a thoughtful integration of proven technology and durable design.
- Superior Insulation & Safety: Utilizing SF6 gas as the insulation and arc-quenching medium, the RMU offers exceptional dielectric strength, allowing for a more compact footprint compared to air-insulated units. The gas compartment is hermetically sealed, ensuring long-term stability and eliminating the risk of internal contamination.
- Robust Glock Switching Mechanism: The integrated Glock switches provide a reliable and visible means of isolation. Their design ensures clear ON/OFF indications and a secure mechanical interlock system, preventing incorrect operation and enhancing personnel safety during maintenance.
- Exceptional Environmental Protection: The unit boasts an IP67 rating, making it dust-tight and protected against temporary immersion in water. Combined with its corrosion-proof design (often utilizing high-grade stainless steel or coated materials for key components), it is well-suited for indoor locations with potential moisture, dust, or corrosive atmospheres, such as basements, industrial plants, or coastal facilities.
- Compact and Space-Saving: The gas-insulated design allows for a significantly smaller size than traditional switchgear, freeing up valuable floor space in electrical rooms or substations.
- Low Maintenance Requirements: The sealed-for-life SF6 gas system and robust mechanical components minimize the need for routine maintenance, reducing lifecycle costs and operational downtime.
- Flexible Configuration: The RMU can be configured with various feeder options, metering units, and protection devices to suit specific network requirements. Remote monitoring and control capabilities are often available as optional features.
Below is a summary of key technical specifications:
| Parameter | Typical Specification |
| Rated Voltage | 12kV / 24kV |
| Rated Frequency | 50Hz / 60Hz |
| Rated Normal Current | 630A |
| Short-Time Withstand Current | 20kA / 25kA for 3s |
| Insulation Medium | SF6 Gas |

Frequently Asked Questions (FAQ)
Q1: What is the primary advantage of using SF6 gas in this RMU?
A: SF6 gas provides excellent dielectric strength and arc-quenching properties. This allows for a much more compact and reliable unit compared to air-insulated alternatives, enabling installation in space-constrained indoor locations.
Q2: Is the IP67 rating sufficient for outdoor use?
A: While IP67 offers high protection against dust and temporary water immersion, this unit is specifically designed as an Indoor RMU. Outdoor installation would require additional considerations for UV resistance, wider temperature ranges, and permanent weatherproofing, which are not covered by the IP67 rating alone.
Q3: What maintenance does the SF6 gas system require?
A: The gas system is typically sealed for life under normal operating conditions. Regular maintenance mainly involves visual inspections, checking for any signs of leakage (which is rare), and verifying mechanical operation. It is designed for minimal intervention.
Q4: Can the Glock switches be operated remotely?
A: The standard version features manual operation with a clear mechanical indicator. However, a motorized operating mechanism is available as an optional feature to enable remote control and integration into SCADA systems.
Q5: What are the typical applications for this Indoor SF6 RMU?
A: It is ideal for indoor medium voltage distribution in commercial buildings, industrial plants, data centers, hospitals, universities, and utility substations where space, reliability, and protection from environmental factors are critical.
Q6: Does the corrosion-proof design include all external parts?
A: The corrosion-proof design typically applies to the enclosure and key structural components, often using materials like coated steel or stainless steel. Specific material details for different parts are available upon request.
Q7: What standards does this product comply with?
A: The RMU is designed and tested in accordance with international standards such as IEC 62271-1 (common specifications) and IEC 62271-200 (for AC metal-enclosed switchgear). Compliance with other regional standards can be discussed based on project requirements.
Q8: What is the lead time for an order?
A: Lead times vary based on order quantity, configuration complexity, and current production schedule. Generally, standard configurations can be delivered within a few weeks. We provide accurate lead time estimates upon receipt of your specific requirements.
