Under the effort of all staff, our company gradually expands year by year, and has been playing the leading role in this industry. Our main product is fault recording and analysis equipment, which has won the No.1 in national technology competition, and the sales also kept No.1 since 2005.

At present, the main products are:
1) Electric power fault recording and analysis equipment
2) Time synchronization systems
3) Relay protection systems
4) Measuring instruments

Fault recording and analysis equipments of ZH, including transmission line recording, generator recording, transformer recording and portable recording, all have self intellectual property rights. For high performance, these equipments have supplied the electric power with full solution for fault analysis and acquired many prizes and honors.

For example,
ZH-1 won the prize of Sci-tech Achievement of Hubei Province in 2001.
ZH-2 won the second prize of Scientific Development of Hubei Province in 2003.
ZH-3x was the latest embedded fault recording and analysis equipment.

Because of good reputation, advanced technology, excellent quality and service, our company has got great development. Since the first ZH series fault recording and analysis equipment came out in 2000, we have already sold over 6,000 sets. Some have been used in many national key projects.

For example:

The Three Gorges to Shanghai 500 kV HVDC transmission project, which is the largest HVDC transmission project of State Grid Corporation. It was the first time that domestic fault recorder was applied to the Three Gorges.

The right bank project of the Yangtze River Three Gorges project and 500kV HVDC transmission project in May 2005.

The Fourth transformer substation in Huazhong area of the Three Gorges in June 2005.

North of Beijing 500kV transformer substation, the Olympic project, in Sept 2005.

State Grid 1000kV south of Jindong to Nanyang to Jinmen extreme high voltage project in Aug. 2007, which is the first 1000kV extreme high voltage project of China.

Yunnan to Guangdong 800kV HVDC transmission project in Dec. 2007, which is the first extreme HVDC transmission project.

Lanxi 500kV transformer substation digital fault recorder project of Zhejiang Province in Sep. 2008. these recorders totally meet IEC61850 protocol standards.

The reconstruction project of the left bank of the Three Gorges in Oct. 2008. In this project, our products started to replace the previous overseas equipments.
