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?
OA 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.

Opening types
- Hook stick switch: Used in distribution substations. Switched by stick;
- Tandem hook stick switch: Used in distribution substations. Switched by stick;
- Center break disconnector: Used in industrial substations due to their simpler construction;
- Vertical break disconnector: Used mainly in transmission substations due to their excellent endurance to short circuit;
- Vertical reach disconnector: Used in substation inputs/outputs, connection of upper x lower busbars and bypasses;
- Double side break disconnector: Excellent endurance to short circuit, with smooth operation, since they do not require compensation springs;
- Horizontal semi-pantograph disconnector: Used mainly in transmission substations due to their excellent endurance to short circuit. Because of its compact size, it can be used in areas with little space;
- Vertical semi-pantograph disconnector: Used in substation inputs/outputs, connection of upper x lower busbars and bypass.
Applications
- Power distribution substations operated by stick switch;
- Industrial substations;
- Generation and transmission substations;
Special applications (laboratories, automatic systems for equipment monitoring, etc.).
