High-votage winding adopt the continuous interleaved structure to improve the distribution characteristics under surge voltage and obtain relatively uniform electric field distribution. The strips and cushion blocks are chamfered to imporve the reliability of insulation. The is winding oil guide structure inside the transformer winding,so that each area within the winding can be fully cooled,thus reducing winding temperature rise and wingding hot spot temperature rise and extending the insulation service life.
The core material is high -quality cold-rolled high magnetic conductive graion-oriented silicon steel sheets and the advanced automatic cutting line imported from Georg is used for blanking. The burrs at the sheared edges are controlled at smaller than 0.02mm. The silicon steel sheets adopt the process of non-laminated tup yoke and the lap joint of silicon sheets is 45° full sloping step. Intergrated pressurizing and epoxy adhesive are applied to make the three limbs and two yokes a strong and smooth entity of high vertical accuracy,hence their no-load performance effectively improved and noise reduced.
3. Fuel tank and accessories
The tank wall adopts wide steel sheets not but weled,instead,they are corrugated to reduce weld joins and improve mechanical strength. Meanwhile,corrugated tank walls have dissipation effects,thereby reducing noise. The secondary circuit wiring board and control cabinets are all made with stainless steel. The tank edges have dual sealing grooves. The outer sealing material is used to prevent air and ultraviolet ray from damaging the interal sealing material,thereby improving the service life of sealing elements to the maximum extent and ensuring the sealing reliability.
We have established good cooperative relationship with many large transformer component manufacturers and can make diverse components based on different user requirements. Our production, R&D and sales services are strictly performed according to international certification and ISO quality management system.
