Beijing Dongyao International Trading supplies SCB10/SCB13 dry-type distribution transformers — engineered for industrial parks, data centers, and critical infrastructure across Southeast Asia, Africa, and the Middle East.
Epoxy resin cast-coil design with vacuum-impregnated windings. Self-extinguishing, explosion-proof, and maintenance-free — the preferred choice for modern power distribution.
Vacuum-cast epoxy resin insulated windings with no voids. Partial discharge <5 pC at rated voltage.
Cold-rolled grain-oriented silicon steel, step-lap mitered joints. No-load losses 30% below IEC limit.
F1 fire rating. Epoxy resin is inherently flame retardant — no toxic fumes, no oil leakage risk.
140% continuous with forced air cooling (AF). 170% short-term emergency overload.
Six reasons SCB cast-resin transformers dominate modern power distribution — from fire safety to environmental resilience.
Epoxy resin is self-extinguishing (F1 rating). No oil means zero fire risk, no toxic smoke, no explosion hazard. Ideal for indoor installations and populated areas.
IEC 60076-11Epoxy cast coils are hydrophobic, corrosion-resistant, and withstand 95% RH humidity. No condensation tracking. Proven 30-year+ service life in tropical climates.
Tropical RatedVacuum-cast resin ensures zero voids in the insulation. Partial discharge <5 pC vs. industry standard of 10 pC. Longer insulation life, higher reliability.
<5 pC @ 1.2 UnCompact footprint — install directly inside buildings, close to load centers. No need for separate transformer rooms or firewalls. Reduces construction costs significantly.
Indoor RatedNo oil filtering, no dielectric testing, no leak monitoring. Annual visual inspection is sufficient. Lower total cost of ownership over 25+ year lifecycle.
Maintenance-FreeZero oil — no environmental contamination risk at end of life. Epoxy resin is inert and recyclable. Compliant with RoHS and WEEE environmental directives.
RoHS CompliantFrom industrial parks in Vietnam to data centers in South Africa — our transformers power the infrastructure that powers the world.
Distributing power across factory zones in Bac Ninh, Binh Duong, and emerging industrial corridors. Each park needs 5–50 units of 500–2,500 kVA.
Mission-critical power distribution for Tier III/IV data centers. F1 fire rating, zero oil, high overload capacity. Alibaba, Tencent-grade reliability.
Step-up and distribution transformers for solar farms and wind parks. Designed for harsh outdoor conditions — sand, heat, and high UV exposure.
Hotels, hospitals, airports, and shopping malls. Safe indoor installation near people. Silent operation (<55 dB) suitable for noise-sensitive environments.
