Product overview

● scientific calculation means: use advanced electrical, magnetic, thermal and mechanical force calculation software to calculate the distribution of electromagnetic field and magnetic leakage, conduct wave process analysis, and select reliable insulation margin to ensure reliable product performance.

● reasonable structural layout: the iron core adopts multi-stage step lap full tilt structure to reduce no-load loss and noise; The iron core is supported by a round rod, and the coil adopts a hard paper cylinder to enhance the short-circuit resistance; The coil adopts baffle to guide and circulate the oil flow and reduce the coil temperature rise; Special shaped fins are used to raise the fin heat dissipation center to reduce the temperature rise of the oil surface: all internal insulating parts and metal structural parts are rounded to reduce partial discharge.

● advanced process measures: the iron core is automatically cut, with high precision and small burr. The process of not stacking iron rollers is adopted, and the surface is coated with double h curing adhesive and bound; Vertical winding of coil, with numerical control tensioning device; The body adopts the phase suit process, and the lead wire adopts the overall preassembly; The body adopts the fully automatic kerosene gas-phase drying process.

● perfect quality assurance system: control product quality in strict accordance with ISO19001 quality system.

● ssz11-240000/230 transformer has passed the national full set type test and sudden short circuit test.

● products of other voltage combinations, loss values, connection groups and capacities listed in the table can be provided according to user needs.
