Audited Supplier Qinghao dry type distribution transformer includes cast resin insulation, amorphous alloy and on-load tap changer type, which provides general security for environment with its non-flammable, self-extinguished, toxic gas-free structure and low noise level.
Energy Storage Transformer (EST) is a specialized transformer designed to efficiently store and release electrical energy in power systems. It is a new type of power transformer that can step up or step down the voltage levels as needed to facilitate the charging and discharging processes by converting electrical energy into magnetic energy and store it, and then output electrical energy. It can balance the load of the power system, improve the reliability and stability of the power grid, reduce energy consumption and pollution, and realize intelligent terminals and intelligent operation and maintenance, which is a new type of power equipment with broad application prospects.
