Company Introduction
Beijing Leader&Harvest Electric Technologies Co., Ltd was established in 1998. It is a high-tech enterprise with annual growth rate of more than 50%. The headquarter locates in Zhongguancun Science&Technology Park with area of 40000m2. There are 700 employees and about 500 sets of advanced producing equipments and detecting instruments. Owning itself intellectual property, Leader&Harvest has got certificates of ISO9001, ISO14001 and China Top Brand.

As the leader manufacturer of high voltage VFD (variable frequency drive) in China, Leader&Harvest has researched technology of vector control and speed adjustment on synchronous motor successfully. In March 2008, Leader&Harvest got an order of 2 sets of 10000kVA/10kV VFD which adopted technology of double synchronous switch. The VFD can drive one or several asynchronous/synchronous motors to soft start. Leader&Harvest sales achievements broke through 3000 sets in September 2009 and the company gets top market share for 6 years consecutively.

Since the first VFD produced in 2000, Leader&Harvest has provided products and services across all the world including Asia, Europe, Africa, North America,South America and Oceania. The drive mainly applies in industry of power generation, steel, mining, petrol, cements and resource. With Harsvert VFD, users benefit a lot in energy saving and emission reduction and get considerable economic effect. Besides high voltage VFD, Leader&Harvest also provides completed control solution and service, such as coordinating control, cooling control.

In 2006, Leader&Harvest set up Chino-Harvest Wind Power Technology Co., Ltd which aims at researching wind power converter. Chino-Harvest keeps ahead of world class technology of variable speed constant frequency wind power converter. It has developed 1.5~2.5 MW converter successfully which works in wind power plant.

The company depends on advanced technology that is from the national key electric lab of Tsinghua University, and possesses a group of high quality R & D team who are of rich experience. Leader&Harvest will always insist on tenet of " advanced technology, excellent quality and well-appointed service" and endeavor to accomplish target of being "world class company in high voltage drive field".
