Quality
Control
Framework
Full-process quality control system ensuring excellence and reliability from raw materials to finished product delivery for every transformer and voltage stabilizer.
Incoming Quality Control IQC
Establish supplier admission and evaluation mechanisms, prioritizing qualified raw material suppliers.
Strict testing of silicon steel permeability, copper conductivity, and insulation material voltage ratings.
In-Process Quality Control IPQC
Core: Monitor lamination flatness and stacking factor.
Winding: Inspect turn count and winding tension.
Assembly: Check clearances and wiring correctness.
Final Quality Control FQC
100% full-load testing including insulation resistance (≥100MΩ), withstand voltage, and regulation rate verification.
Quality Traceability QTM
Establish complete production digital records for each batch, enabling rapid root cause tracing within 24 hours.
