USA, Ohio, Kent: Bison has developed a series of motorised operator systems designed to enhance the performance and reliability of switchgear used across electric transmission and distribution networks. These motor-driven solutions allow for precise, remote, and automated control of electrical circuits, helping utilities improve grid safety and efficiency.
The company’s DC PowerStar® Right Angle Gear Motors, DC 562 Series Offset Parallel Shaft Gear Motors, and DC 750 Series Right Angle Gear Motors are among the products used by switchgear manufacturers to achieve smooth operation and consistent performance under demanding conditions. Each model provides various speed and torque ranges and features a hollow output shaft for straightforward system integration.
Designed for compactness and durability, Bison’s gear motors combine high torque output with low current draw, ensuring energy-efficient operation. The systems also maintain reliable performance in temperatures as low as –40°C (–40°F), supporting use in outdoor or submersible installations.
Motorised operators have become an integral part of modern switchgear designs, enabling automation, reducing manual operation, and helping prevent downtime in critical power applications. They are increasingly applied in auto-transfer systems, padmount assemblies, and subgrade vault installations, where remote operation and condition-based monitoring are priorities.
By integrating such motorised mechanisms, switchgear manufacturers can support utilities in strengthening grid reliability, reducing maintenance costs, and improving operational safety.
