Product Description

SCB11 series epoxy resin dry type transformers are reliable medium low-loss cast-resin indoor power distribution transformers, upgraded from traditional SCB10 models with optimized energy-saving performance. Adopting vacuum epoxy resin casting technology and full copper foil windings, this F-class insulated transformer features stable operation, ultra-low partial discharge, fireproof, explosion-proof and fully maintenance-free advantages. Complying with IEC and GB industry standards, SCB11 series covers full capacity and multi-voltage grades, widely used for industrial workshops, urban power grids, commercial buildings, schools, hospitals and general indoor power distribution projects worldwide.

As an oil-free and environmentally friendly power device, SCB11 dry type transformer completely avoids oil leakage, fire and explosion risks, featuring high safety for closed indoor power distribution rooms. The integral rigid casting structure provides strong mechanical strength and excellent short-circuit impact resistance, adapting to daily grid fluctuations and continuous full-load operation. Supported by natural air cooling (AN) and optional forced air cooling (AF), it has stable overload capacity and low operating noise. Equipped with F-class high-temperature insulation system and standard IP20 protection grade, it offers outstanding dust-proof, moisture-proof and anti-pollution performance without daily maintenance. It is the most cost-effective and reliable conventional energy-saving power distribution solution for general industrial and civil power supply projects.

Core Features

Upgraded SCB11 Energy-saving Performance: Optimized core lamination and electromagnetic design, lower no-load and load loss than SCB10 series, effectively reducing long-term operational power consumption with higher cost performance.

Full Copper Foil Winding Structure: Premium low-resistivity copper foil windings deliver excellent conductivity and heat dissipation, ensuring stable voltage output and long service life.

High Safety & Environmental Protection: Flame-retardant epoxy resin cast body with self-extinguishing capability, no toxic gas emission, zero fire and explosion risk, fully suitable for densely populated indoor public and industrial scenarios.

Ultra-low Partial Discharge: Precision full-vacuum integral casting process ensures partial discharge ≤10pC, maintaining stable insulation performance and strong anti-aging ability for lifelong operation.

Strong Short-circuit Resistance: Reinforced integrated casting structure enhances overall rigidity, effectively resisting short-circuit impact and mechanical vibration deformation, ensuring grid operational stability.Full Voltage & Capacity Coverage: Supports mainstream voltage combinations including 10/0.4kV, 6.3/0.4kV, 6.3/0.69kV and full capacity range, compatible with most industrial and civil power supply systems.

Maintenance-free Operation: Fully sealed oil-free structure with zero leakage risk, no daily maintenance required, greatly reducing on-site operation and management costs.

Stable & Low-noise Operation: Optimized vibration damping structure suppresses operating noise and vibration, realizing quiet and continuous full-load operation for indoor substations.
