On December 29, 2023, the KF83 relay tester from KINGSINE was used in cooperation with a local company in Harbin, China, for power emergency repair. Despite the harsh outdoor conditions of -20 degrees Celsius, the team successfully carried out the repair task and completed it satisfactorily.
The advanced technology and robust design of the KF83 enable it to operate smoothly even in adverse weather conditions. This also reflects KINGSINE's philosophy and pursuit, focusing on quality, performance, and customer satisfaction by providing high-quality products with new technologies.
Developing lightweight and high-performance products has always been a focal point for KINGSINE. Recently, KINGSINE has introduced the new portable relay protection tester, KFA310. Compared to previous products, it offers upgraded features and higher performance, making it more capable of meeting various testing requirements.
KINGSINE will continue its dedicated efforts to uphold product quality and bring new products to its customers.
