Product descriptions from the supplier
Description
A Ring Main Unit designed, manufactured and fully type-tested according to IEC 62271-200, RMR is widely used in power distribution systems, such as utilities, industries, buildings and new energy power stations.
This 12/24kV SF6 gas-insulated switchgear (GIS) is specifically engineered for secondary distribution networks and ring main unit applications. It integrates compact design with high reliability, utilizing SF6 gas insulation to ensure stable performance in harsh environments. Ideal for urban power grids, industrial parks, and commercial complexes, it supports efficient ring network distribution, enabling safe and continuous power supply with minimal footprint.
Key Features
SF6 Gas Insulation：Superior dielectric properties of SF6 gas ensure excellent insulation performance, withstanding high voltage and reducing the risk of flashovers, even in humid or dusty conditions.
Compact & Space-Saving：Slimmer cabinet design compared to air-insulated switchgear, saving up to 40% installation space—perfect for urban areas with limited room.
High Reliability for Ring Networks：Optimized for ring main unit topology, supporting looped power supply and rapid fault isolation to minimize downtime in secondary distribution systems.
Low Maintenance：Hermetic gas enclosure reduces leakage risks (≤0.1% per year) and extends maintenance intervals, lowering long-term operational costs.
Enhanced Safety：Equipped with internal arc protection (AFLR) and interlocking mechanisms to prevent unauthorized operation, ensuring personnel and equipment safety.

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
