High Voltage Vacuum Contactor (JCZ9-40.5kV)
The 30kV(40.5kV) high-voltage vacuum contactor series is a new product developed by our company in response to market demand. It features high-quality vacuum interrupters and employs a contemporary assembly design with a compact and lightweight structure, ensuring ease of use and stable performance. This contactor is suitable for distribution systems in sectors such as metallurgy, mining, and petrochemicals, and is used to control high-voltage motors, transformers, and capacitive loads at 30kV(40.5kV) and below. It serves as a main switch for remote control, providing stable and reliable performance. Available models include permanent magnet and electromagnetic holding types.
This series of contactor features a permanent magnet mechanism and an intelligent controller, ensuring a long lifespan, excellent synchronization, no bounce, and stable reliability.
The main circuit uses a fully enclosed structure with sealed poles, offering good insulation performance suitable for frequent operations in harsh environments.
Single-pole, double-pole, and three-pole configurations can be customized for using as main and bypass switches in various equipment, as well as serving as main switches in devices like SVCs.
