W.H.L. was the first one introducing the idea of network power supply and SF6 Ring Main Unit (Switchgear) to China in 1986. It promoted the development of urban power supply system. Now, W.H.L. has sold more than 20000 sets MV Switchgears. These switchgears are widely applied in substations and 10kV user-terminated power distribution stations, such as the Shanghai Substation, Sixiang Substation, Guangzhou Liwang Skyscraper, Zhuhai Arena, Shenzhen Railway Station, Shenzhen Airport, Shenzhen Window of the World, etc.

EFACEC is one of the largest electrical and electromechanical provider based Portugal. EFACEC well-known switchgears are accorded with the IEC standard. Among them, Fluofix and Normafix switchgears has passed all required tests performed by China National High Voltage Apparatus Quality Center, and their rated short-time current can up to1600kA. These switchgears have the following characteristics :
SF6 insulation is highly reliable, free of maintenance, with minimum life 20 years;
Small size, simple structure, and easy installation and maintenance.
Satisfy for all kinds of design solution.
Good compatibility to power automatic distribution system
Good performance and competitive prices.

FLUOFIX is a Switchgear (GIS) insulated with SF6 gas provides the best technical and economical solutions, even in the most demanding situations. All electric components are equipped in a isolated tank.
