Hitachi Energy’s DDHV – ‘V’ type center break disconnector is a compact, reliable and easy-to operate substation equipment.
Suitable for applications up to 145 kV voltage level, DDHV is designed for installation in outdoor switchyards. It has two moving insulators per phase arranged in a ‘V’ configuration, which makes DDHV design compact and simple. Due to this, DDHV is a preferred solution for substations where space is costly or limited.
DDHV disconnectors enable flexible design and reliable operations. Built-on earth switches are available and can be mounted on one or both sides of the disconnector.
The SDF disconnectors are available up to 550 kV, 4000 A and 63 kA. These type of disconnectors have a low friction design and offer minimized contact resistance. They are equipped with dead center interlocking for reliability in extreme conditions. Some other important features of these disconnectors are:
The GW55 disconnectors are available upto 245 kV, 3150 A and 50 kA. These disconnectors have a low friction design and offer minimized contact resistance. They are equipped with interlocking for reliability in extreme conditions. Some other important features of these disconnectors are:
