Descripton
YB-type compact substations, also known as European-style prefabricated substations, comply with GB17467-1998 for high-low voltage substations and IEC1330 standards. Compared to conventional civil substations, they offer key advantages: small footprint, compact structure, easy mobility, which shorten construction periods, reduce land occupation and infrastructure costs. Their on-site installation and maintenance are simple, and they can be positioned closer to load centers to improve power supply quality, minimize power losses, and enhance distribution network reliability. These substations integrate complete functions for power transformation, distribution, transmission, measurement, compensation, system control, protection, and communication.
Composed of four parts—high-voltage switchgear, low-voltage distribution panels, distribution transformers, and enclosures—YB substations use high-voltage air load switches and offer dry-type or oil-immersed transformers. The enclosures feature excellent insulation and ventilation structures with upper ventilated ducts to minimize temperature rise in HV/LV transformer rooms, equipped with temperature-controlled forced ventilation and automatic thermal management. Each independent unit is fitted with comprehensive control, protection, live-line indication, and lighting systems.

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 -
