Product Overview
Engineered to perform reliably in high-demanding, safety-critical power distribution scenarios, our SCB Series Class I energy efficiency dry-type transformer represents a premium solution for modern power systems. It has been rigorously tested and officially certified to fully meet GB 20052-2020 Class I - the latest and most stringent national energy efficiency standard for power transformers, embodying industry-leading energy-saving performance.
In direct performance benchmarking against the mainstream SCB14 dry-type transformer, our product achieves extraordinary efficiency improvements: its no-load loss is reduced by 25%, load loss is lowered by 18%, and the comprehensive energy efficiency ratio exceeds the threshold of GB 20052-2020 Class I standard by an extra 15%. These quantifiable performance upgrades bring tangible value to end-users: they drastically cut long-term power consumption, generate substantial savings on operational electricity costs, lower carbon emissions, and fully satisfy strict national energy conservation regulations.
Safety is integrated into every design element. The transformer adopts cutting-edge epoxy resin casting technology and a 100% oil-free structure, which completely eradicates the risks of oil leakage, fire hazards and environmental contamination that plague traditional oil-immersed transformers. It delivers exceptional flame retardancy, explosion-proof performance and operational stability, ensuring continuous and secure power supply even in the most high-risk working environments.

● Commercial centers, shopping malls and urban public complexes
● Airports, transportation hubs and large-scale terminal facilities
● Chemical plants, petrochemical industrial parks and flammable & explosive working zones
● Nuclear power plants and nuclear safety-related power infrastructure
● Docks, ports, offshore platforms and shipboard marine power systems
● Other high-safety scenarios demanding strict fire and explosion protection
Type And Meaning
Product Features
Low noise
Our dry-type transformer is made of high-magnetic-permeability high-quality grain-oriented cold-rolled silicon steel sheets and adopts 45° fully inclined step joints, which can effectively reduce no-load noise and make the transformer operating noise ≤45dB under rated load.
No pollution
Our transformer adopts high-quality epoxy resin vacuum casting (VPI process), which forms a solid sealed body after curing. It does not contain any toxic substances (such as polychlorinated biphenyls), will not pollute the environment, and complies with environmental protection directives such as RoHS.
Maintenance-free
The transformer coil is completely wrapped in resin, isolating it from air and moisture, effectively preventing the insulation material from getting damp and aging, and requiring almost no maintenance throughout its life cycle.
