Eco-Friendly Oil Immersion Transformers
Transformer is a kind of static electrical equipment. It utilizes the principle of electromagnetic induction to raise or lower the input voltage to the same frequency AC voltage output to meet the needs of high-voltage power delivery, low-voltage power distribution and other purposes. Modern industry, agriculture and scientific research and other sectors, widely used as an energy source of electricity, and in a variety of electrical equipment, the need for different voltage power supply, so the transformer was widely used.

1. Selection Notes
(1) Capacity and voltage level: Determine the rated capacity and voltage level of the transformer according to actual needs. This depends on the total capacity of the power-using equipment, load characteristics and future expansion needs.
(2) Use of occasions: consider whether the transformer is used for the main transformer of the power system, or for the distribution transformer of specific equipment. The performance requirements for transformers may vary from one application to another.
2. Focus on product quality
(1) Appearance and manufacturing process: the appearance of high-quality products should be free of corrosion, no damage, paint layer uniformity, bright color; manufacturing process, transformer winding terminals should be neat, contact distribution in line with the requirements, fixed and reliable; coil embedded in the line between each other after the distance is appropriate; iron core fastening degree is appropriate and clean and clean; all parts of the linkage is firm and reliable.
(2) Technical documents: check whether the technical documents of the transformer is complete, including factory number, inspection certificate number, instruction manual and so on. This information helps to understand the performance and quality of the product.

Brand Story
On the shore of the blue and deep ocean, a story of energy and dreams was born - the birth of HaiKun Petrochemical Technology Co. This company, like the first ray of sunshine penetrating the sea mist in the morning, illuminated a new chapter in the petrochemical industry.
The founders of HaiKun Petrochemical Technology Co., Ltd. knew that quality and innovation are the foundation of a company in today's increasingly globalized world. So HaiKun Petrochemicals started from the source and built its own factory to ensure the purity and excellence of every drop of petrochemical products. Here, the industry's top technicians and advanced production equipment are brought together to transform raw energy into petrochemical products that meet market demands through a precisely controlled production process, from base oils to high-end chemicals, all of which reflect HaiKun's ultimate pursuit of quality.
