Product Introduction
The SCBH15 amorphous alloy dry-type transformer is an efficient, energy-saving and environmentally friendly transformer. It adopts amorphous alloy core material and features low loss, low noise and high short-circuit resistance. Its no-load loss is significantly lower than that of traditional silicon steel sheet transformers, which can effectively reduce energy waste. It is suitable for places with high requirements for low-carbon environmental protection, such as urban distribution networks, industrial parks and new energy application scenarios. This transformer does not require insulating oil, has excellent fire resistance, is safe and reliable to use, and has low maintenance costs, making it an ideal choice for achieving green power development.
Scope of Application
The SCBH15 amorphous alloy dry-type transformer is widely applicable to fields with high requirements for energy conservation and environmental protection, such as urban power grids, industrial parks, commercial complexes, residential communities, hospitals, schools, airports and other public facilities. In addition, it also has important application value in new energy fields, such as photovoltaic power generation, wind power generation and distributed energy systems.
Product Description
Core Material: Adopts an amorphous alloy core with ultra-low loss characteristics. Compared with traditional silicon steel sheets, it can effectively reduce no-load loss and operating costs.

Transmission LineIn transmission lines, a "π" connection involves breaking the original line from Substation A to Substation B and inserting Substation C, forming a "π" configuration. After the "π" connection, the original single line is divided into two independent transmission lines. Following the "π" connection, Substations B and C may both be powered by Substation A (in this case, Substation C receives power via a feeder from Substation B's busbar, or possibly from another voltage point within Substation B);Encyclopedia09/04/2025 -
What are the principles of forced re-energization of transmission lines?Principles of Forced Re-energization of Transmission LinesRegulations for Forced Re-energization of Transmission Lines Correctly select the forced re-energization end of the line. If necessary, change the connection configuration before forced re-energization, taking into account the reduction of short-circuit capacity and its impact on grid stability.
