News Release: Acrel Medical IT Isolation Power System Deployed at Luanda General Hospital, Angola

2026-07-31

Acrel Electric, a leading manufacturer of medical isolated power supply solutions, has successfully delivered 8 complete sets of its professional Medical IT System to Luanda General Hospital in Angola, a flagship China-aided hospital reconstruction and expansion project undertaken by China Railway No.4 Engineering Group Co., Ltd. The customized power solution safeguards continuous, leakage-free power for operating rooms, ICUs and CCUs, addressing critical patient safety risks in Class 2 medical locations across Angola’s largest comprehensive hospital.

Medical facilities pose two unique power hazards that conventional TN-S grounded distribution cannot resolve. First, lengthy surgical procedures demand zero power interruption; blackouts mid-operation create life-threatening risks. Second, precision diagnostic and surgical devices directly contact human tissues, where micro leakage currents may trigger cardiac hazards for patients. Global medical codes mandate ungrounded IT power architecture for all Class 2 medical areas, paired with real-time insulation monitoring to detect insulation degradation before dangerous faults emerge.

Acrel’s full-stack medical IT system integrates core hardware tailored for African hospital operation environments:

AITR Series Medical Isolation Transformers: H-class insulation material limits temperature rise, with low inrush current and low noise output; capacity ranges cover 3.15kVA to 10kVA and hold full CE certification.
AIM-M Insulation Monitoring Devices: Real-time tracking of insulation resistance, overload and over-temperature, with fault alarm relay output, RS485 and CAN bus communication for centralised monitoring.
AKH-0.66P26 Protective Current Transformers: Maximum measuring current up to 60A, 2000:1 transformation ratio, cabinet DIN fixed installation.
AID Remote Alarm Indicators: Wall or panel-mounted display terminals, powered by matched DC24V power supplies, enabling frontline medical staff to instantly view insulation fault data.
Optional add-ons: ASG test signal generators and AIL insulation fault locators for circuit-by-circuit fault pinpointing, supporting up to 16 monitoring channels via cascaded AIL150 modules.

Two standard distribution architectures were rolled out for different clinical zones at Luanda General Hospital. For operating rooms, AID alarm panels are embedded on ward intelligence panels so surgeons can monitor power health during live operations. For ICUs and CCUs, centralised AID displays are installed at nursing stations to allow nurses to oversee all isolated power cabinets across critical care wards at a glance. Customers can select a basic version without fault location, or an enhanced version with full-circuit insulation fault tracing to simplify post-failure maintenance.

As Angola’s largest upgraded public medical complex after reconstruction, Luanda General Hospital delivers high-volume inpatient, surgical and intensive care services for residents across Luanda Province. Acrel’s IT isolation system eliminates lethal leakage risks and avoids total power shutdowns caused by single ground faults. Unlike grounded TN-S circuits, IT systems maintain continuous power supply after the first insulation fault, buying valuable time for medical teams to complete ongoing treatments before maintenance shutdowns.

“This China-aided hospital project marks a milestone of Chinese medical power technology serving African healthcare infrastructure,” said the overseas product director of Acrel Electric. “Our CE-certified medical IT solutions are engineered to meet international medical electrical standards, with complete monitoring and alarming functions that adapt to unstable grid conditions common in African regions. By securing reliable, safe power for life-critical medical equipment, we help local medical institutions lift clinical service standards and protect patient safety.”

The handover of the full Acrel Medical IT package supports the long-term operation of Luanda General Hospital, solidifying Sino-Angolan healthcare cooperation. Moving forward, Acrel will continue supplying certified medical isolation power systems for China-aided medical projects across Africa, providing full lifecycle technical support for operating room and critical ward power safety worldwide.
