The main insulating materials inside Liquid-filled transformers are transformer oil, insulating cardboard, cable paper, telephone paper, and crepe paper. Here are some detailed explanations of Liquid-filled transformers insulating materials.This is the content list:Insulating cardboardCable paperPho

Oil-filled transformers are a new type of high-performance transformer with a more reasonable structure and better performance. The three-dimensional wound core of Oil-filled transformers has an equilateral triangular three-dimensional arrangement, and there is no air gap in the magnetic circuit. Th

The wet transformer has several independent oil systems that are isolated from each other. When the wet transformer is running, the oils in these independent oil systems are not connected, and the oil quality and operating conditions are different. So what is the oil system of the wet transformer? T

Dry Transformer is wide utilized in native lighting, high-rise buildings, airports, terminal CNC machinery instrumentality, and different places. Simply put, a Dry Transformer refers to an electrical device whose core and windings aren't immersed in insulating oil.

In my country, epoxy resin vacuum casting Dry-type transformer dominates the market. In addition, from the main distribution transformers to power plant excitation transformers, plant transformers, rail transit traction rectifier transformers, high-current electric furnace transformers, nuclear power plants, marine, oil production platforms, and other special transformers and multi-purpose multi-field development. In recent years, Zhejiang Shuntong Electric Co., Ltd. has developed and mass-produced these special products in many fields.

Oil-filled transformers use oil as the main insulation means of the transformer and rely on oil as the cooling medium, such as oil-immersed natural cooling, oil-immersed air cooling, oil-immersed water cooling, and forced oil circulation. Oil-filled transformers can operate as specified on the nameplate under the specified cooling conditions, but the top oil temperature should not exceed 90℃. To prevent the insulation of oil-filled transformers from aging, the top oil temperature should not exceed 85℃ frequently, and the alarm setting should be set at 80°C. The following is an introduction to the performance characteristics of oil-filled transformers.
