Split Current Transformer | 70% Faster Installation

ZHNYU ELECTRIC operates a 10,000+ square meter manufacturing facility equipped with over 100 production machines, including automated winding, assembly, and testing lines. This scale allows us to produce more than 500,000 Split Current Transformers annually while maintaining strict quality control. Every unit undergoes 100% routine testing for ratio error, phase displacement, and insulation, plus periodic type tests per IEC 61869. Our ISO9001-certified quality management system ensures consistency. In a recent audit, we achieved a 99.8% first-pass yield. With 34 years of experience, we continuously invest in R&D and process optimization to deliver reliable, high-accuracy transformers. Our vertical integration—from core lamination to final assembly—enables competitive pricing and fast lead times, serving 60+ export countries.

Our Split Current Transformers feature a precision-engineered hinged core that opens and closes with a simple latch mechanism, allowing installation around live conductors without disconnection. This design reduces installation time by up to 70% and eliminates hazardous shutdowns. The core faces are precisely ground to minimize air gaps, ensuring high accuracy and low phase error. The housing is made of flame-retardant, UV-resistant polycarbonate, providing IP54 protection (IP65 optional). The secondary terminals are clearly marked for polarity, and the lead wires are double-insulated for safety. Ideal for retrofit projects, renewable energy systems, and industrial control panels, our split-core transformers have been successfully deployed in a 200 km railway project and a 30 MW solar farm, proving their reliability in harsh environments. With a wide range of window sizes and current ratings, they offer flexibility for diverse applications.
