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.

Our new lab was qualified for test and start service this year, GIS manufacturer sent their GIS products to our lab for AC test, actually we haven't started business of testing service, so far we only produce and sell testing equipment, this is our first trial.  
Completed the installation and commissioning for 1500kV AC Test Transformer System and ±1200kV HV DC Generator, both systems perform well, all test results are qualified.
We have finished the production and factory test of 2000kV mobile impulse voltage generator, which is designed to facilitate site test of GIS and other electric systems, this mobile system is put in two special design container, one for impulse generator, one for control (with air condition), for testing, only need to ship container to site, open the container, then it will install the impulse generator automatically by hydraulic system.
FSHV supplied a impulse voltage generator to Canadan transformer manufacturer, they mainly produce dry type distribution transformers, the photo is our engineer help and train them carry out impulse voltage test according to IEEE C57.98 standard, test precedure is half wave, 2 times chopping wave, then full wave, finally compare the voltage and current wave of half and full to check the performance of this transformer.
FSHV big energy impulse current test systems, based on impulse voltage generator structure, are mainly used for testing whole set of lightning arresters whose residual voltage is high (90kV, 120kV or higher), and also the testing of MOV blocks in a suitable discharge rack.
The system in photo is 600kV 60kJ 20kA impulse current / voltage test system, is designed for arrester residual votlage test up to 20kA 90kV, also it can output impulse voltage up to 600kV for testing of insulators and others.
Also we have higher solution for higher residual voltage test, like 800kV 20kA...
