Product Introduction
The oil natural air forced cooling transformer is a novel high - performance device featuring a more rational structure and superior performance. Its three - dimensional wound iron core is composed of equilateral triangles arranged in three - dimensions, with no air gaps in the magnetic circuit. This design leads to a more compact and shortest - length three - phase winding, and the cross - sectional area of the iron core column approximates a circle. As a result, its performance is further enhanced, with lower harmonic losses, reduced noise, and minimized third - harmonic components.

What is the purpose of using step-down transformers in transmission lines and step-up transformers at distribution substations?
Purpose of step-down transformers in transmission lines
Adapt to user power consumption: The voltage in transmission lines is high and not suitable for direct use. oil immersed step-down transformers reduce the voltage to a safe level to meet the power needs of end-users such as households and enterprises.
Protect electrical equipment: Most electrical appliances can only operate properly at a specific voltage. Reducing the voltage can prevent electrical appliances from being damaged by high voltage.
Purpose of step-up transformers in distribution substations
Reduce transmission losses: The voltage generated by power plants is low. After oil type step-up transformers increase the voltage, the transmission current decreases, thus reducing the power losses in the transmission lines and enabling efficient long-distance power transmission.
Match line standards: Transmission lines have specific voltage requirements. Three phase step-up transformers increase the generated voltage to make it meet the operating standards of the lines.
