Fully sealed oil immersed amorphous alloy transformers are suitable for use in power systems with an AC frequency of 50Hz and a rated working voltage of 10KV or below. They are used as distribution transformers in enterprises such as petroleum, metallurgy, chemical, textile, light industry, and places with high dust.
Execution standard: GB/T1094.1、GB/T1094.2、GB/T1094.3、GB/T1094.5、GB/T25446、GB/T7595、JB/T3837、GB20052 The transformer products produced by our company meet the new version of the above standards.
Usage environment:
1. The altitude of the installation site shall not exceed 1000m, and the ambient temperature shall not exceed 40 ℃.
2. The usage environment has a relative humidity of 100% and a temperature range of+40 ℃ to -25 ℃.
3. When installing the product, it should generally be 800mm away from walls and other obstacles, and there should be a distance of 300mm between adjacent transformers. The above distance can be adjusted appropriately for distribution boxes and other situations where installation space is limited.
4. In general, transformers can be placed directly at the usage site and can be put into operation after installation and inspection. For situations with seismic and other special requirements, the foundation for installing transformers should be embedded with bolts and fixed with bolts and nuts.

Three‑phase Oil‑immersed Amorphous Alloy Transformer
Amorphous alloy is a new type of strip material that does not have a crystal structure, has low magnetization power and high resistivity, resulting in low eddy current losses. Using this material as the iron core can produce a new type of energy-saving transformer, which is an ideal product for the upgrading of distribution networks. This product is particularly suitable for areas with insufficient electricity and large load fluctuations, where daily maintenance cannot be carried out. Because the transformer adopts a sealed structure, the insulation oil and insulation medium are not affected by environmental pollution, so it can operate in humid environments and is an ideal distribution equipment in many urban and rural distribution networks. Especially suitable for areas with insufficient electricity and large load fluctuations, where daily maintenance cannot be carried out.
