High-quality lightning arresters: A reliable choice

Do you know? Each year, 37% of transformer failures worldwide are related to lightning overvoltage - we have a lot to say about this. As a veteran in the lightning arrester industry with 15 years of experience, Zhejiang Shuangfeng Electrical Co., Ltd. Today, let's talk about something practical: not only must the technology be solid, but also ensure that customers' money is spent where it truly matters. Our products are diverse, suitable for differentiated scenarios such as high temperature and high humidity in Africa and smart grids in the United States. They have passed the IEC 60099-4 international certification and have become the preferred partner for energy projects in more than 50 countries around the world.
Don't be fooled by parameters. The core points are just three:
Our metal oxide arresters (MOAs) can handle extreme environments well, not by gimmicks. The resistance sheet is made of high-purity zinc oxide. It is heated to a full temperature in a 1200℃ oven like baking a pizza, and then aged for 48 hours - just to make the residual voltage 15% lower than that of ordinary products
To be honest, in the field of lightning arresters, having only the technology is not enough:
The steep wave impact tester in our laboratory has been in operation all the time. It gives "electric shock" hundreds of times every day, with a failure rate of 0.2% (the industry average is 1.5%). There are also 12 quality inspection processes, including steep wave impact tests, to safeguard key equipment such as transformers and transmission lines with the "zero defect" standard.
We also have drop-out lightning arresters that utilize power frequency short-circuit current to actuate the disengaging device, automatically disengaging the grounding terminal of the disengaging device, causing the lightning arrester components to fall off and exit operation. This prevents the accident from further expanding and makes it easier for maintenance personnel to promptly identify problems for maintenance and replacement. It has fundamentally solved the problem that the fault points of lightning arresters are not easy to detect, and it is convenient to replace them without cutting off the power supply, ensuring the stability of daily power supply, reducing a large amount of power maintenance workload, saving a lot of manpower, and greatly improving work efficiency. The principle of its falling off is similar to that of a fuse in a fuse fuse blowing, causing the fuse tube to fall off. Our company has adopted the most advanced thermal explosion type disconnector in the world at present. It has the advantages of fast action speed, wide action current range, and the ability to withstand the specified current impact and action load.
