Product Description
Oil-immersed power transformers provided by our company have the following characteristics:
1, the use of a new insulation structure, strong resistance to short circuit;
2. Excellent material selection, the core is made of high-quality cold-rolled silicon steel sheet or non-gold alloy core material with extremely low loss; High and low voltage windings are selected high quality high conductivity materials.
3. The electric field, magnetic field, temperature field and impact field are accurately analyzed and calculated by computer, and the corresponding structure and design parameters are determined, so that the impact field intensity and gradient can be reasonably distributed, and the performance can be guaranteed to be excellent and reliable, and the economic and technical indicators are excellent.
4. The design of reducing field intensity is adopted, and local discharge is small.
5. Vacuum oil injection complete seal maintenance free design, no maintenance for life, long service life.
