CONSTRUCTION:
CORE
The core is crafted from cold-rolled grain-oriented (CRGO) silicon steel. Precise automated cutting ensures reduced air gaps, low exciting current, and minimal noise. Each lamination is insulated to guarantee a long, trouble-free core lifespan. Using a 45° stepping alignment technique, no-load current is significantly reduced.
machines thereby ensuring reduced air gap, low exciting current and low noise. Each lamination is insulated from each other to ensure a long trouble-free lifetime of the core. Using 45° stepping all leaning lamination way to laminate. So the no-load current are reduced efficiently.
WINDINGS
The LV winding is made with high-quality foil conductor or copper wire, ensuring balanced ampere-turn and low additional loss. Enhanced short-circuit resistance is achieved, and oil drawings for heat dispersion are scientifically utilized to increase heat dissipation surface area, thus reducing temperature and enhancing overload capacity.
temperature is reduced and the ability of over-load is improved.
Our HV winding is meticulously crafted using premium quality copper wire and an innovative design structure. This sophisticated technique enhances the distribution of the electric field, ensuring superior performance and reliability. With comprehensive lighting impulse analysis, we've significantly boosted the transformer's ability to withstand lightning disturbances.
Through rigorous impulse analysis, our transformers exhibit an enhanced capability to resist lightning impulses, ensuring increased durability and reliability.
TANK
The tank is expertly constructed using high-quality steel. The surface undergoes meticulous rust-proofing, including phosphate coating, and is finished with a robust FVC anticorrosive paint. This ensures long-lasting protection against oil and chemical corrosion.
Its exceptional ability to withstand oil and chemical corrosion makes it ideal for harsh outdoor environments. The tank's aesthetically pleasing design ensures easy installation and maintenance-free operation.
Designed for easy installation, our tanks are maintenance-free, making them perfect for harsh outdoor conditions.

Process Technology:
Core:
Our transformer's core is crafted from high-quality cold-rolled grain-oriented silicon steel with excellent magnetic permeability. Utilizing full 45° slope lamination, we efficiently reduce both no-load loss and no-load current.
By employing Simulating Analysis in core model design, we accurately calculate vibration frequency and size to eliminate core cavity resonance.
A spring connection between the core & windings and core & frame ensures noise levels are reduced by 10 to 15dB below standard.
