In transportation infrastructure, power system reliability is directly linked to operational safety and public order. As critical nodes with high passenger flow and complex operating conditions, railway hubs impose far stricter requirements on power supply continuity, stability, and safety than ordi

Inside DGG Power’s In-House Testing Capability: How We Ensure Product Reliability Before DeliveryFor many overseas customers, product testing is not just a technical step—it is a matter of trust.Before any medium- or high-voltage equipment is installed into a power system, customers want to know one

Root Cause Analysis of a 35kV Vacuum Circuit Breaker Power Frequency Withstand Failure

DGG Power successfully held its first postdoctoral research completion report, where Dr. Huang Jialiang presented innovative solutions addressing cracking issues caused by low thermal conductivity in epoxy casting. The expert panel unanimously recognized the scientific value and engineering significance of his findings. As a key platform for industry–academia collaboration, DGG Power’s postdoctoral workstation continues to drive research transformation and support the company’s progress toward intelligent and green manufacturing.

Project OverviewIn 2021, DGG Power (Denggao Electric Co., Ltd.) once again proved its strong technical capabilities and stable product performance by winning the tender for a key 10kV Ring Main Unit (RMU) project in Beijing.The equipment was specifically supplied for the power-supply system of the H

Vacuum Circuit Breakers (VCBs) are one of the most important electrical protection devices used in medium and high-voltage electrical systems. These breakers are designed to protect electrical equipment from faults such as overloads and short circuits by interrupting the flow of current. As their na
