Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of oil transformers, it is recommended to prioritize checking key technical parameters such as rated capacity, voltage level, and cooling method to ensure compatibility with grid or equipment load requirements.
  • In high-frequency usage scenarios such as industrial plants or substations, attention should be paid to the short-circuit resistance and temperature rise performance of oil transformers to adapt to long-term high load operating environments.
  • When selecting suppliers, reference can be made to product compatibility, business qualifications, enterprise activity, industry performance, and platform statistical information. Such enterprises usually provide more stable supply and technical support.
  • If applied to special scenarios such as new energy generation and grid connection, it is recommended to additionally evaluate the harmonic tolerance and insulation oil environmental indicators of oil transformers to reduce maintenance risks in the future.
  • The industry data support capability of suppliers can serve as an important reference, especially when it comes to parallel operation of multiple transformers, ensuring product parameter consistency is necessary.

Knowledge Base

Q

This article analyzes the core differences between dry-type and oil type transformers, from working principles to applicable scenarios, to help readers make reasonable choices based on actual needs, and introduces the characteristics and advantages of dry-type transformers.

Q

Oil immersed transformers are indispensable distribution equipment in power systems. To ensure the safe and stable operation of the equipment, various experiments need to be conducted before leaving the factory. This article will introduce the factory test standards and their importance for oil immersed transformers.

Q

Oil immersed transformers and ordinary transformers are two commonly used types of transformers. The biggest difference between the two is that oil immersed transformers use insulating oil to insulate the coils, which can provide greater power at the same volume, while also having better insulation and heat dissipation performance.
