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

In modern electrical systems, circuit breakers are critical for ensuring the safety and efficiency of electrical distribution. Vacuum circuit breakers (VCBs) have become a pivotal component in high-voltage electrical protection due to their reliability and performance. This article explores what a v

In modern electrical systems, protection is crucial to ensuring the safe and efficient operation of power networks. One of the most vital components of such systems is the vacuum circuit breaker. It is widely used in medium- and high-voltage applications, where efficient circuit interruption is nece
