Solid-Insulated Ring Main Unit (RMU) | LWX65-12(CVF) Maintenance-Free & Eco-Friendly Power Distribut
Maintenance-Free & Eco-Friendly Power Distribution
Product Details
The LWX65-12(CVF) Solid-Insulated RMU is our most advanced, eco-friendly distribution solution. Featuring a fully encapsulated, epoxy-resin-cast primary circuit, it is completely immune to environmental factors like high humidity, dust, and corrosive air. It is the ultimate choice for challenging locations where maintenance is difficult or impossible.
Why Choose Solid-Insulated Technology?
Zero Environmental Impact: Uses high-performance solid-dielectric materials—fully SF6-free, ensuring total compliance with the strictest environmental regulations.
Immune to Harsh Environments: Fully sealed primary module (IP67-rated) ensures perfect performance in high-altitude, humid, coastal, or dust-prone areas.
Maintenance-Free: The primary circuit is cast in solid insulation, requiring no gas pressure monitoring or internal cleaning, offering a 30+ year lifespan.
Ultimate Safety: Full shielding and grounding of all live parts prevent accidental contact, offering the highest level of operator safety.
Compact & Scalable: Minimal footprint compared to air-insulated units, with a flexible modular design for easy site installation and network expansion.

Product Highlights
100% Maintenance-Free: The primary circuit is fully encapsulated in high-performance epoxy resin, eliminating the need for gas pressure monitoring, internal cleaning, or periodic maintenance—ensuring a 30+ year service life.
Immune to Harsh Environments: With an IP67-rated fully sealed primary module, it provides complete immunity to dust, high humidity, salt spray, and corrosive atmospheres, making it the top choice for coastal and industrial areas.
True Eco-Friendly Design: Completely SF6-free. Uses solid-dielectric technology to ensure zero greenhouse gas emissions, meeting the strictest international environmental safety standards.
Superior Safety & Reliability: Fully shielded primary circuit prevents accidental contact. Its robust, automated mechanism ensures safe switching operations and provides maximum protection for operators and nearby equipment.
High-Altitude Adaptability: Unlike gas-insulated (GIS) or air-insulated (AIS) units, the performance of our solid-insulated RMU is completely unaffected by changes in air pressure, making it ideal for high-altitude power projects.
Modular & Space-Saving: Compact, stackable design significantly reduces the substation footprint, allowing for easy network expansion even in space-constrained urban environments.
Typical Applications
- Coastal regions and high-humidity tropical areas.
- High-altitude zones (unaffected by air pressure changes).
- Underground power substations and flood-prone areas.
- Critical infrastructure requiring zero downtime (Data centers, smart grids).
