Technical Overview
11kV Cast Resin — Safe, Flame-Retardant & Maintenance-Free
Cast resin dry-type transformers eliminate oil leakage and fire hazards, making 11kV dry-type units the mandatory choice for indoor urban substations, shopping malls, hospitals, and offshore platforms. XinHuan utilizes high-grade vacuum epoxy casting technology with quartz filler, ensuring high mechanical short-circuit withstand and moisture resistance.
Both high-voltage (11kV) and low-voltage (0.4kV) windings are wound with electrolytic copper or aluminum foil and encapsulated under high vacuum (<1 mbar). The glass fiber reinforced solid insulation prevents insulation breakdown and resists thermal aging up to Class F (155°C) or Class H (180°C).
Each unit comes equipped with PT100 temperature sensors embedded in every LV phase winding, connected to a digital temperature controller (BWDK series) with automatic cooling fan control, over-temperature alarm, and trip contacts. IP20, IP23, or IP54 enclosures with safety interlocks are available.

Technical Q&A
Frequently Asked Questions — 11kV Dry-Type Cast Resin Transformers (SCB13 / SCB14)
Class F1 certifies fire behavior: self-extinguishing within seconds after removal of external flame, with zero emission of halogen or toxic smoke. Class C2 certifies climatic resistance: safe storage, transport, and energization down to -25°C without resin cracking. Class E2 certifies environmental performance: resistance to heavy humidity (>93%) and severe atmospheric pollution.
Every unit undergoes partial discharge routine testing per IEC 60076-11 clause 14.3. Thanks to void-free vacuum casting under <1 mbar with micro-silica powder filler, our partial discharge level is strictly guaranteed below 10 pC at 1.3×Um (far superior to the standard IEC 60076-11 limit of ≤20 pC).
By installing cross-flow cooling fans beneath the cast coils and linking them to the digital temperature controller, continuous transformer capacity is boosted by +40% to +50% without damaging the Class F (155°C) or Class H (180°C) insulation. This provides crucial emergency peak headroom during summer or industrial surges.
Three high-precision PT100 platinum RTD sensors are embedded directly into the hot-spot of each low-voltage phase winding. They connect to a digital temperature controller (BWDK series) providing real-time LED temperature display, automatic cooling fan start/stop, over-temperature alarm contacts, and trip contacts.
IP00 is the core-and-coil bare assembly for installation inside clean switchgear cubicles. IP20 prevents ingress of fingers or solid objects >12mm for indoor electrical rooms. IP23 adds louvers to prevent water drops falling at up to 60° angle. IP54 sealed outdoor enclosures with air-to-air heat exchangers are available for coastal or dusty environments.
Yes. The epoxy resin completely encapsulates both primary and secondary windings in a solid impervious dielectric monolith. Unlike VPI open-ventilated dry transformers, cast resin units suffer zero degradation from 100% relative humidity, salt mist, or fungus, and require no pre-drying before energization after prolonged shutdown.
SCB14 series reduces no-load idle losses by 15-20% and load losses by 10% compared to legacy SCB11 models. In continuous 24/7 commercial, hospital, or data center operation, the cumulative electricity savings pay back the modest initial price premium within 2.5 to 3.5 years.
Please specify: kVA capacity (50 kVA to 2500 kVA), HV/LV voltage (e.g. 11kV / 0.415kV), conductor material (copper or aluminum), enclosure requirement (IP00 core-and-coil, IP20, or IP23), frequency (50Hz or 60Hz), and destination seaport for an authoritative CIF or FOB proposal in 24 hours.
