Product Introduction

The ZF-LM ZK Series Open Current Transformer is a cutting-edge electrical measurement device designed for use in ring main units (RMUs). Utilizing advanced nanocrystalline soft magnetic materials, this open-core current transformer ensures highly accurate and reliable current sensing in medium-voltage power distribution systems. Its openable design allows for effortless installation and maintenance without interrupting existing circuits, making it an ideal solution for retrofit projects, energy monitoring, and smart grid applications. The ZF-LM ZK Series is engineered to deliver exceptional performance in harsh environmental conditions while maintaining long-term stability.

Product Advantages
1. Superior Accuracy: The nanocrystalline core ensures minimal hysteresis and core losses, providing precise current measurement even under low-current conditions.
2. Easy Installation: The openable design allows for quick, tool-free installation and removal, reducing downtime and labor costs.
3. High Reliability: Excellent thermal stability and resistance to environmental factors ensure consistent performance in demanding applications.
4. Wide Compatibility: Suitable for integration with existing RMUs, energy meters, and protection relays.
5. Future-Proof Design: Ideal for smart grid upgrades, IoT-based monitoring, and renewable energy systems.
6. Cost-Effective: Reduced maintenance requirements and long service life lower the total cost of ownership.
