High-Voltage Oil Transformers
The transformer, belonging to the category of static electrical equipment, leverages the mechanism of electromagnetic induction to modify the input voltage, either elevating or lowering it, while ensuring a consistent frequency in the AC voltage output. This capability aligns perfectly with the requirements of high-voltage power transmission, low-voltage distribution systems, and numerous other applications. Consequently, transformers have become ubiquitous in modern industries, agriculture, scientific research fields, and a broad spectrum of electrical devices, where they serve as flexible and reliable sources of electrical energy tailored to specific voltage needs.

1. Selection Points
Determining the appropriate rated capacity and voltage level of the transformer necessitates an analysis of actual requirements, taking into account the aggregate capacity of power-consuming equipment, load profiles, and future expansion plans. Furthermore, consider the specific occasion of use—whether as a primary transformer for the power grid or a distribution transformer for certain equipment—as this may dictate varying performance specifications.
2. Focus on product quality
Quality products should exhibit an unblemished appearance, absent of corrosion, damage, and featuring a uniform, brightly colored paint coat. In terms of production, transformer winding terminals must be arranged neatly, with contact distribution adhering to specifications, and fixed securely for reliability. Coils must be embedded with adequate spacing, and the iron core should be appropriately fastened and maintained clean. Additionally, all linkage components must be securely fastened.
For a comprehensive understanding of the product, it's crucial to inspect the completeness of technical documents, which should include factory serial numbers, inspection certificate details, and an instruction manual, among others.
