Distribution of energy. Traction substation "turnkey" Metro and Light rail transport overhead line power supply equipment Switchgear of Distribution and Sectioning
Design
Structurally Switchgear of Distribution and Sectioning is made as one-side services metal cabinet (casing manufactured by RITTAL, Germany), divided into five compartments.
Each compartment is equipped with one disconnector, type EDT 4000, with visible double-break. Each compartment has an individual door, locked with a key.
The door is equipped with an overview window for disconnector contacts position observation. Disconnectors are installed in the rear end of compartment; manual drive is in the front end. Front and rear parts of compartment are divided with a panel with overview window. Each disconnector drive axis is controlled from its reducer.
