3、 Product Structure

Iron core: High quality cold rolled silicon steel sheets and multiple sets of fully inclined seam stepwise lapping and binding structures are selected, effectively improving the distribution of magnetic flux density within the iron core,

Meet the energy-saving and environmental protection requirements of low loss and low noise of transformers.

Winding: high-quality oxygen-free copper material/high-strength enamelled wire (or paper wrapped wire) winding and multi-layer cylindrical (or pie/spiral) structure are selected, with uniform ampere turn distribution

Uniform, reasonable insulation structure. High voltage winding and low voltage winding can be wound together, with high efficiency and compact coils. And optimize cooling, heat dissipation, and temperature rise design,

Bind and clamp the winding turns and compact the winding ends with laminated wood to enhance the mechanical strength and short circuit withstand capacity of the winding, ensuring the safety of the transformer

Reliable operation.

Body: It adopts a core-free structure and a limit and hanging plate structure around the body, effectively solving the suspension problem of the body. The body does not shift, avoiding transportation bumps

Adverse effects on product quality. The fasteners used for the body are self-locking nuts, which can ensure that they will not loosen after long-term transportation. Therefore, new products are being put into production

No inspection is required before shipment.

Oil tank: The corrugated oil tank and expansion radiator oil tank structure are selected, which are maintenance-free, leak free, small in size, good in heat dissipation, and novel in structure. The oil conservator is eliminated

And moisture absorbers. The change in oil volume depends on the elasticity of the corrugated oil tank and expansion radiator to compensate and adjust. As the temperature increases/decreases, the transformer

The increase or decrease of insulating oil causes expansion and contraction, while isolating the inside of the transformer from the air. The insulating oil of the transformer does not come into contact with oxygen and water, slowing down materials such as insulating oil and paper

The aging speed of the product can extend the service life of the product. And the sealing part of the oil tank adopts oil resistant silicone seals, which are not prone to aging and cracking, and need not be replaced after years of use.

However, the new product is simple to operate and maintain, saving users the cost of power outage maintenance.

Surface treatment and coating: After phosphating treatment, the surfaces of components and oil tanks are sprayed with three types of anti moisture paint (moisture, mildew, and salt spray), which can meet various requirements

The use environment ensures that the surface treatment layer does not fall off, does not corrode, has bright colors, is bright, and has a beautiful appearance.
