For the past 20 years, we have been focusing on electrical power quality, protection, transmission, control and distribution products and systems across low to high voltages. In recent years, we also strive to protect the environment by adding clean and renewable energy product lines into the portfolio such as the vertical axis wind turbine, building integrated photovoltaic cells, combined heat and power gas engines, diesel generators, boilers, heat exchangers, absorption chillers and biomass energy.
