Product Description

SCB14 series epoxy resin dry type transformers are the latest super ultra-low loss energy-saving indoor distribution transformers, an upgraded version of SCB13 series for higher energy efficiency. Adopting high-performance high-permeability silicon steel core and full copper vacuum casting technology, this F-class insulated transformer features further reduced no-load and load loss, ultra-low partial discharge, fireproof, explosion-proof and full maintenance-free performance. Compliant with latest IEC and national energy efficiency standards, SCB14 series covers full capacity and multi-voltage grades, ideal for smart grids, green buildings, data centers, new energy stations and high-standard low-carbon power distribution projects worldwide.

As a completely oil-free and pollution-free power device, SCB14 dry type transformer eliminates hidden dangers such as oil leakage, fire and explosion, ensuring high safety for indoor closed operation. The integral rigid casting structure provides excellent mechanical strength and strong short-circuit impact resistance, adapting to complex grid fluctuations and long-term full-load continuous operation. With natural air cooling (AN) and optional forced air cooling (AF), it has strong overload capacity and low operating noise. Equipped with F-class high-temperature insulation system and standard IP20 protection grade, it features outstanding dust-proof, moisture-proof and anti-pollution capabilities without daily maintenance. It is the most advanced energy-saving and environmentally friendly power distribution solution for modern high-standard smart power grid construction.
