Designed and developed in compliance with NBR IEC 62.271-102 standard, they ensure the insulation of equipment or segments of substation lines when in the open position, allowing confirming visually that the isolated segment is powered down. |
What is a switch-disconnector?
A switch-disconnector is an electromechanical device able to interrupt or establish low-intensity currents at the moment they are driven, and, under normal operating conditions, in the closed position, to withstand high-amplitude currents, such as those of short circuits.
Designed and developed in compliance with NBR IEC 62.271-102, their function is to ensure the insulation of equipment or parts of substation lines when in the open position, allowing confirming visually that the isolated segment is de-energized.
