Advanced Engineering Design

Multi-Strand Copper Winding

Parallel-wound copper conductors reduce eddy-current losses with optimized current density ≤2.5A/mm².

Full Insulation System

All terminals withstand 10kV/min ground insulation tests with zero discharge anomalies.

Stepless Regulation System

Single-phase motor-driven iron core enables continuous reactance adjustment without power interruption.

Oil Management System

Moisture absorber maintains dielectric stability
Drain valve for oil sampling/maintenance
Thermal-monitored mineral oil (IEC 60296)

5-Step Capacity Selection

Step	Capacity	Current	Bushing Output
1	150kVar	25A	Yes
