The complete switchgear (KRU) of the SVEL series with a nominal voltage of 35 kV is a modular metal structure consisting of four isolated compartments: withdrawable element, cable connections, busbars, and secondary switching circuits. The enclosure is made of high-quality anti-corrosion steel with zinc or aluminized zinc coating, and the external elements have a polymer powder coating.

Design Features:

• Withdrawable Element Compartment: includes the withdrawable element (WE), shutter mechanism, interlocks, and guides. The shutters automatically close when the WE moves from the operating to the control position, ensuring maintenance safety.
• Withdrawable Element: a trolley on which various equipment is installed depending on the cell scheme, including a power vacuum circuit breaker, sectional disconnector, or voltage transformers.

Technical Specifications:

• Nominal Voltage: 35 kV
• Nominal Current: up to 3150 A
• Climatic Version: UHL (moderate and cold climate) and T (tropical climate)
• Placement Category: 1 (outdoor operation) and 2 (under shelter)
