With the extensive application of high-power switching devices, the quality of electric power is growing problem seriously, which causes the current (voltage) distortion, producing a large number of harmonics.

We are now proud to offer SHSDEC harmonic filters for delivery to the global markets. Our high quality harmonic filters are manufactured at Shanghai Shuang Dian Electric Co., Ltd., located in China - one of the most advanced harmonic filters manufacturing facilities in the world.

Shanghai Shuang Dian Electric Co., Ltd. Has produced harmonic filters with ratings up to 1, 140V, and is a China's leader in research and development of tomorrow's harmonic filter technology.

For the overseas markets, we are currently focusing on providing harmonic filters primarily of 400V and 690V.

Shanghai Shuang Dian Electric Co., Ltd. is a leading manufacturer of modularization design harmonic filters. The modularization design is utilized for all SHSDEC harmonic filters. The modularization design offers many benefits along with FPGA, optical fiber communication, and hot-swappable technologies. Some of the advantages are: -More powerful computing capability -Strong anti-interference and transmission capability -Easy to maintain both on-line and off-line -THDi equal to or less than 3% -Far less investment than other world famous competitors -15 days of delivery time Shanghai Shuang Dian Electric Co., Ltd. Owns proprietary intellectual property rights on various flexible technologies for AC power transmission and distribution devices. We also supply transmission and distribution system stability analysis, electric energy quality enquiry, and equipment having high electric power.

SHSDEC harmonic filters have provided their customers with harmonic filters featuring excellent performance and a level of high reliability proven through more than 10 years of operational performance and experience. We will continue to be a leader in the development and manufa
