The LDS135-10 is a double cable core current transformer featuring a newly developed high-permeability core that ensures high measurement accuracy. The secondary winding is fully enclosed in vacuum-cast, flame-retardant plastic shell, providing excellent insulation and safety. This transformer is designed for easy installation by allowing the primary cable to pass directly through its core, making it ideal for electrical systems with equipment voltages up to 0.72kV.
Widely used for current metering, signal collection, and relay protection, the LDS135-10 supports a rated secondary current of 5A and operates at standard frequencies of 50Hz or 60Hz. It complies with IEC 60044-1 and IEC 61869-1 & 2 standards and is intended for indoor installation, ensuring reliable and safe performance.
