The LDZC55-35 is a single cable core current transformer featuring a newly developed high-permeability core for excellent measurement accuracy. Its secondary winding is fully enclosed within a vacuum-cast, flame-retardant plastic shell, providing robust insulation and durability. The transformer is designed for easy installation by allowing the primary cable to pass directly through the core, making it ideal for electrical cable systems with equipment voltages up to 0.72kV.
Widely used for current metering, signal collection, and relay protection, the LDZC55-35 supports primary currents up to 1500A and secondary currents of 5A or 1A. It complies with IEC 61869-1:2007, IEC 61869-2:2012, and IEC 60044-1 standards, ensuring reliable and safe performance. The transformer is suitable for installations up to 2000 meters altitude.
