Hospital Operating Suite Isolated Power System & Medical-Grade IT Transformers
Medical-grade IT isolation transformers with ultra-low leakage current (<200µA), Faraday electrostatic shielding, and insulation monitoring for hospital operating rooms and ICUs.
1. Project Context & Operational Challenge
Medical operating rooms, intensive care units (ICUs), and cardiac cath labs demand ungrounded Medical IT power distribution per IEC 60364-7-710 to guarantee zero micro-shock risk to patients and continuous power during first line-to-earth electrical faults.
2. Customized Engineering Solution
XinHuan manufactured custom Medical-Grade IT System Isolation Transformers featuring double Nomex insulation, copper Faraday electrostatic shield grounded between primary and secondary windings, built-in PT100 temperature sensors, and ultra-low leakage current (<150µA).
