Main production process and characteristics:
1． The core is made of high-quality oriented cold-rolled silicon steel sheet, which is manufactured by the latest process of stepped seams, which effectively improves the distribution of magnetic flux density inside the core, reduces noise and reduces loss.
2． Select high-quality copper wires to ensure the surface quality, insulation and geometrical requirements of the wires; select high-quality oxygen-free copper materials, that is, copper materials with lower resistivity. On the premise of ensuring the effective cross-section of the core, increase the number of stages of the core and reduce the diameter of the core, thereby reducing the average turn length of the coil. At the same time, adopt a reasonable insulation structure, reduce the winding factor, and reduce assembly tolerances. , To achieve the purpose of reducing the average number of turns of the coil, and ultimately to reduce the winding length of the coil and reduce the load loss of the transformer.
3． All components are double-sealed to prevent leakage. All seals are made of high-quality cork rubber, which can effectively prevent light aging, electrical aging and thermal aging.
4． Equipped with "telemetry" signal thermometer and pressure relief valve.
5． Field-free hanging core, high reliability, high impedance, low loss, low noise, low temperature rise, low partial discharge, no leakage, etc.
This series of products can be widely used in electric power and power distribution systems below 35kV, such as power plants, power stations, industrial and mining enterprises, and user distribution stations.
