Design
The Switchgear, SVEL-K-1.4 Series rated voltage 6(10)kV is a modular type metal structure consisting of 4 insolated compartments: drawout elements, cable connections, busbars, and secondary switching circuits. The circuit breaker is located at the embedded drawout element.
The frame of the Switchgear is made on a high precision cold forge equipment out of a high quality galvanized steel. Outside elements (doors, side panels, etc.) are coated with the powder paint material that ensure high-level anti-corrosion protection within the ambient environment.
The compartments are divided by the removable metal partitions that ensure reliable mitigation of an arc fault sequences within a single compartment. No welded joints are used, and all elements are pivot-fixed. To ensure protection of the operating personnel, the doors and shutters are equipped with the special locks of the patented design, preventing the release of arc combustion products towards the operator.
