Product descriptions from the supplier
Overview
The core component of the on-load capacity-adjusting voltage-regulating transformer is suitable for rural power grids with large seasonal load changes and some urban commercial areas, development zones, industrial areas and other power distribution areas with significant day and night load changes. When the load of the power grid is light or close to no load, the project product will intelligently change the transformer from large capacity to small capacity operation, greatly reducing the line loss of the power grid and saving electric energy. The product includes a voltage regulating function, and the number of tap positions is 3/5.
At the same time, the project product can automatically adjust the voltage according to the fluctuation of the grid voltage, thus stabilizing the grid voltage and improving power quality. Function: The horizontal structure is used to arrange the contacts on both sides of the switch to save the installation space of the transformer and reduce the manufacturing cost of the transformer. The product adopts multi-break arc extinguishing technology. Under the same stroke, the arc of multiple breaks is longer than that of a single break. , which is beneficial to the recovery of the arc gap dielectric strength. In addition, since the power supply voltage is applied to several fractures, the voltage applied to each fracture is reduced, that is, the recovery voltage of the arc gap is reduced, which also helps to extinguish the arc.

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 -
