Product descriptions from the supplier
Description
XGN15-12 SF6 high voltage ring main unit is a new generation of air-insulated metal-enclosed switchgear. Through continuous improvement, its perfect performance and flexible assembly characteristics can meet the changing needs of the market.
XGN15-12 SF6 high voltage ring main unit provides technical solutions for various applications. The device is safe, convenient and compact in size. For 12kV ring network power supply, double radiation power supply system. It can also be used for terminal power supply, as a control and protection device for electrical energy, and is also suitable for installation in box-type substations.
XGN15-12 high voltage SF6 gas insulated rmu is a compact and scalable switchgear suitable for distribution automation systems. It has the interlock function to prevent the load switch from being closed, to prevent the grounding switch from closing the load switch and the lower door when the grounding switch is in the closed position. Sensing technology and the use of the latest protection relays make the switchgear suitable for operation in demanding hospitals and airports, etc。

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 -
Understanding Transformer Neutral GroundingI. What is a Neutral Point?In transformers and generators, the neutral point is a specific point in the winding where the absolute voltage between this point and each external terminal is equal.
