What are the characteristics and advantages of oil-immersed transformers? Why choose an oil-immersed transformer?

2025-11-10

Oil-immersed transformers are conventional power conversion devices that rely on insulating oil for both heat dissipation and insulation. Their core feature is “using oil as the medium.” Their key advantages include suitability for large-capacity applications, low cost, and high stability. The primary reason for choosing them lies in their practical value in outdoor and heavy-industrial environments.

Where are dry-type transformers primarily used?

2024-11-07

A dry-type transformer is an “electricity-hungry converter” that doesn't rely on oil for cooling but instead uses air or fans to dissipate heat. Its core function is to step down high-voltage electricity to lower voltages—for example, converting 10kV grid power into 380V industrial power or 220V household power. It has neither an oil tank nor insulating oil, making it both safe and environmentally friendly.

How to choose a cost-effective box-type substation?

2025-11-10

Properly determine the capacity and specifications: Based on the actual electricity load conditions, accurately calculate the required transformer capacity. As a general guideline, it is recommended to leave a margin of 10% to 15% above the peak actual load to avoid blindly selecting an excessively large capacity, which could lead to increased costs and higher no-load losses. At the same time, determine the appropriate voltage level according to project requirements.

What factors affect the price of a packaged substation?

2025-11-10

Capacity and Specifications: The larger the capacity of a packaged substation, the higher the specifications required for its core components—such as transformers and switchgear—and the higher the associated costs, leading to a corresponding increase in price. In addition, voltage levels—such as 10 kV and 35 kV—also affect the price. Equipment operating at higher voltage levels has more stringent technical requirements, which in turn drive up costs.

What is the process for a box-type substation, and where is it primarily used?

2025-11-10

The core of a box-type substation is a compact power supply device that is prefabricated in the factory and installed on-site. The process revolves around “prefabrication—transportation—installation—commissioning,” and its applications are focused on outdoor and temporary/emergency power supply scenarios.
