A common summer thunderstorm nearly turned into a regional power supply disaster. Recently, along an important 500-kilovolt transmission corridor in a certain province, a rare explosive damage occurred to an operating zinc oxide arrester in a hub substation due to the lightning overvoltage. The loud noise not only completely destroyed the arrester but also caused […]
In high-voltage power transmission and distribution networks, system reliability is non-negotiable. As a leading manufacturer specializing in Metal-Oxide Surge Arresters (MOA)—commonly known as lightning arresters or surge arresters—we provide complete units to global EPC contractors and critical components like MOV (Metal-Oxide Varistor) discs to other arrester manufacturers. This guide addresses the key technical and commercial
In a power system, the oil-immersed transformer is the heart, and the transformer bushing is a critical “arterial connection point.” It safely brings the internal high-voltage conductor out of the tank while maintaining reliable insulation to ground. A substandard bushing can cause equipment failure and outages, or in severe cases, lead to explosions. Therefore, knowing
Insights from Industry HeadlinesRecently, numerous countries have announced unprecedented investment plans for grid infrastructure. For instance, in early 2024, the U.S. Department of Energy unveiled a $10.5 billion “Grid Resilience and Innovation Partnerships” program, focusing on modernizing transmission lines and large power transformers. Simultaneously, the EU’s “RepowerEU” strategy and China’s 14th Five-Year Plan for a
