The oil-free design of dry transformers solves the risk of oil leakage

In oil-immersed transformers, insulating oil is used as a cooling and insulating medium, which is essential for the normal operation of the equipment. However, during long-term use, due to various factors such as equipment aging, seal failure, and improper operation, oil-immersed transformers are at risk of oil leakage. Once the insulating oil leaks, it will not only cause the performance of the equipment to deteriorate, but also may pollute the surrounding environment and even cause safety accidents such as fire.
In contrast, dry transformers use air or other non-liquid media for insulation and heat dissipation, abandoning the use of insulating oil. This oil-free design completely eliminates the risk of oil leakage and fundamentally solves the safety hazards of oil-immersed transformers. Dry transformers achieve good insulation performance and heat dissipation effects by using high-performance insulating materials (such as epoxy resin, glass fiber, etc.) and optimized heat dissipation structures, ensuring the safety and reliability of the equipment in normal operation and short-circuit fault conditions.
The oil-free design of dry transformers also brings many other advantages. It avoids the additional cost and time investment caused by aging, replacement and maintenance of insulating oil. The oil-free design makes dry transformers more environmentally friendly and will not pollute the environment. Dry-type transformers are small in size, light in weight, and occupy little space. They are easy to install and maintain and are suitable for various complex installation environments.
