12kV Three-Phase AC Power Distribution Device

Engineered for reliability, this device offers stable insulation performance and a high protection level, ensuring safe and consistent operation in demanding electrical environments.

Key Benefits

✅ Stable Insulation: Optimized for long-term performance.
✅ High Protection: Designed for safety and durability.
✅ Versatile Application: Suitable for diverse power distribution needs.

Target Applications

Ideal for industrial and mining enterprises, high-rise buildings, residential communities, and general power distribution systems (50Hz).

Overview

CKFZ-12/630-20 Indoor High-Voltage AC Vacuum Load Switch and CKFZR-12D/T125-31.5 Vacuum Load Switch Fuse Combination Device are designed for three-phase AC 50 Hz power systems with a rated voltage of 12 kV. Developed by Comking based on advanced technology, they are suitable for industrial and mining enterprises, high-rise buildings, residential communities, campuses, hospitals, docks and other power distribution applications, and can be used as indoor three-phase ring network power supply equipment or terminal power supply equipment.

Performance Advantages

Stable insulation performance:The vacuum interrupter is installed inside the ring main unit’s resin insulation cylinder, ensuring stable and reliable insulation performance.
High protection level:The interlocking mechanism automatically meets the “five-prevention” requirements, improving operational safety and preventing misoperation.
Good suitability:The vacuum switch is capable of breaking a 20 kA short-circuit current. When combined with protection devices, it can realize various protection functions for different application requirements.
Safe and stable:The load switch and cabinet door are mechanically interlocked. With a visible disconnection point and high breaking capacity, the product ensures safe and stable operation.
