Welcome to FIVESTAR

Fivestar HV Testing Equipment Co., Ltd (hereafter referred to as FSHV), is the overseas office of Jiangsu Qiyuan Leiyu Electrical Technology Co., Ltd, which is the biggest and earliest manufacturer of high voltage testing equipments in China.

Since 1980, our factory started cooperating with Shanghai JiaoTong University, producing HV AC, DC, impulse testing systems used in electrical applications, such as power cables, power transformers, instrument transformers, GIS switchgears, capacitors, insulators, arresters, generators, motors and etc.

In 2013, our factory became the subsidiary of CECEP (China Energy Conservation and Environmental Protection Group, governed by SASAC of the State Council, one of the biggest state-owned company), and founded FSHV, engaged in overseas marketing promotion.

We have invested new factory construction with area of 80,000 m², which will be the biggest manufacturer of high voltage testing equipment all over the world, it will be completed in 2015. And we are pleased to announce our quality management system has been approved to ISO 9001:2008.

We have supplied a set of 6000kV impulse voltage test system to Baoding Tianwei Transformer Manufacturer for EHV transformer testing, and successfully completed installation and commissioning in their lab in Qinhuangdao company. This 6000kV impulse voltage generator consists 20 stages, each stage is 300kV, it is the highest voltage rating in transformer manufacturers till now. The photos show the 800kV converter transformer under impulse test.
