The transformer adopts a high-efficiency C-type wound silicon steel core with optimized magnetic circuit design for stable and energy-saving operation.
Advantages include:
Lower magnetic loss
Higher operating efficiency
Reduced heat generation
Low operating noise
Stable continuous-duty performance
The core is manufactured from premium new silicon steel laminations with excellent oxidation resistance and long service life.
Compared with traditional laminated cores, the C-core structure provides:
More compact size
Better magnetic performance
Improved structural strength
Easier installation in compact control cabinets
100% Copper Winding — Full Rated Power

The BKC transformer uses high-purity copper enameled wire winding with no aluminum substitution.
Benefits:
Excellent electrical conductivity
Low resistance
Strong load capacity
Stable voltage output
Reduced voltage drop
Lower operating temperature rise
The winding adopts precision compact winding technology to ensure accurate voltage transformation and reliable long-term operation.
Epoxy Resin Encapsulation for Harsh Environments
The transformer is fully encapsulated with high-quality epoxy resin, sealing both the winding and core structure completely.
Moisture & Dust Protection
The encapsulated structure effectively isolates:
Underground humidity
Water vapor
Dust
Corrosive gases
This greatly improves insulation performance and operational reliability in mining environments.

Anti-Vibration & Impact Resistance
After curing, the epoxy resin firmly secures the internal structure, helping the transformer withstand:
Equipment vibration
Mechanical shock
Transportation impact
This reduces risks of:
Coil breakage
Core loosening
Internal structural damage
Flame-Retardant & Enhanced Safety
The epoxy encapsulation material features excellent flame-retardant performance, helping reduce fire risks caused by short circuits or harsh underground operating conditions.
