Main Overview

SC(B)H15 amorphous alloy dry‑type transformer adopts advanced amorphous alloy as core material to achieve dramatic reduction in no‑load hysteresis loss. Core and windings are fully sealed via epoxy resin vacuum impregnation.
It features flame retardancy, explosion‑proof performance and maintenance‑free operation, stably running within‑25℃ ~ 45℃ ambient temperature. Compared with traditional silicon‑steel dry‑type transformers, its no‑load loss can drop down to approx. 30%. With outstanding anti‑corrosion, low‑noise and strong short‑circuit withstand performance, this model is ideal choice for carbon‑neutral‑oriented projects from 30kVA to 2500kVA.

Product features:

1. Ultra‑low No‑load Loss & Outstanding Energy‑saving
Adopting amorphous alloy core material, no‑load loss & no‑load current is merely ~30% of conventional silicon‑steel sheet transformers. It brings remarkable OPEX reduction and supports carbon‑emission‑reduction goals for long‑run operation.

2. Reliable Anti‑corrosion Protection
Amorphous alloy core is fully encapsulated by epoxy resin plus high‑temperature resistant silicone gel. It effectively prevents core rust and amorphous fragment shedding, providing solid mechanical protection for core and windings.

3. Ultra‑low Operating Noise
Optimized magnetic‑flux‑density design plus specialized noise‑reduction materials & manufacturing processes. Operating noise is 5‑15 decibels lower than standard silicon‑steel dry‑type transformers, suitable for noise‑sensitive indoor sites.

4. Superior Short‑circuit Withstand Performance
Three‑phase three‑limb core structure with robust compact clamping assembly. The product has passed strict sudden short‑circuit withstand test, guarantees high mechanical stability under fault conditions.

5. Excellent Thermal Performance & Intelligent Protection
Epoxy vacuum‑casting delivers low partial discharge and low temperature rise. Forced‑air cooling allows short‑term 150% rated‑load operation. Equipped with intelligent temperature monitoring system, which cyclically displays three‑phase winding temperature, controls cooling fans automatically and outputs alarm & trip signals.

6. Wide‑range Environment Adaptability
Stable working from‑25℃ up to 45℃. Flame‑retardant, explosion‑proof and pollution‑free, maintenance‑free for continuous service. Custom‑built accessories such as tap‑changer and anti‑condensation heater are optional.
