Product Description

SCB18 series epoxy resin dry type transformers are the latest top-tier Grade 1 ultra-low loss indoor distribution transformers, the most advanced upgraded version of SCB14 series. Adopting high-performance ultra-high permeability silicon steel core and optimized electromagnetic finite element design, this F-class insulated full-copper transformer achieves industry-leading energy-saving performance with greatly reduced no-load and load loss. Featuring vacuum epoxy resin casting, ultra-low partial discharge, full fireproof, explosion-proof and maintenance-free design, SCB18 fully complies with the latest international and national first-level energy efficiency standards. It is the preferred high-end power solution for smart grids, zero-carbon parks, data centers and high-standard green power distribution projects worldwide.

As a fully oil-free, zero-pollution and high-safety power device, SCB18 dry transformer completely avoids oil leakage, fire and explosion risks, suitable for closed indoor high-density power distribution environments. The integral rigid casting structure features ultra-high mechanical strength and excellent short-circuit impact resistance, capable of adapting to complex grid fluctuations and long-term full-load continuous operation. Equipped with natural air cooling (AN) and optional forced air cooling (AF), it has strong overload capacity and ultra-low operating noise. With F-class high-temperature insulation system and standard IP20 protection grade, it delivers outstanding dust-proof, moisture-proof and anti-pollution performance without daily maintenance. It is the most advanced, energy-saving and reliable power distribution equipment for modern high-end smart power grid and zero-carbon construction projects.
