The SCB13 630kVA three-phase dry-type transformer is recognised for energy efficiency, safety and stable performance in factories, commercial buildings, hospitals and data centres.
Key facts:
(1) parameters - 630 kVA; HV 10/11 kV; LV 0.4 kV; 50/60 Hz; AN/AF cooling; Class F (or H) insulation; Dyn11; no-load loss ≤980 W; load loss ≤6200 W; impedance 6%; temperature rise ≤100 K; IP20/IP23; noise ≤60 dB - verify against the applicable GB/T 10228 / IEC 60076-11 edition and the batch test report;
(2) structure - high-permeability silicon steel core with step-lap design reduces flux leakage, no-load loss and noise; windings are vacuum-cast in epoxy resin, protecting against moisture, dust, short circuits and mechanical stress;
(3) performance - lower no-load/load losses than earlier SCB series; oil-free design eliminates leakage and fire hazards (indoor installation); low maintenance; stable operation in high humidity, dust, limited ventilation and load fluctuation;
(4) tests - insulation resistance, no-load loss, load loss, temperature rise, partial discharge (≤10 pC typical) and short-circuit impedance tests before delivery;
(5) applications - industrial plants, malls and offices, hospitals and data centres, renewable-energy distribution.
