Execution standard: GB/T1094.1、GB/T1094.2、GB/T1094.3、GB/T1094.4、GB/T1094.5、GB/T6541、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, the ambient temperature shall not be higher than 40 ℃, not lower than -25 ℃, the highest daily average temperature shall be 30 ℃, and the highest annual average temperature shall be 20 ℃.
2. Operating environment, relative humidity not exceeding 90% (ambient temperature 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.

SZ20‑M.RL On‑load Tap‑changing Oil‑immersed Wound‑core Transformer
The oil immersed on load tap changer with a three-dimensional winding iron core transformer includes a three-phase three-dimensional winding iron core, a body, and an on load tap changer. The transformer includes a low-voltage coil and a high-voltage coil wound on each phase column of the three-phase three-dimensional winding iron core in sequence from inside to outside, and multiple tap heads are left on each phase high-voltage coil. Each tap head is connected to the on load tap changer through a lead wire, and the number of turns of the high-voltage coil is changed by switching the tap heads in each phase high-voltage coil connected to the on load tap changer, so as to adjust the output voltage of the transformer under load.
The oil immersed on load voltage regulating three-dimensional coiled iron core transformer can achieve on load voltage regulation, reduce transformer no-load loss and noise, have good heat dissipation, low temperature rise, long service life, and do not require corner rings. It is also easy to process and manufacture. It fully complies with China’s energy-saving policy, improves voltage quality and reliability, and is a green energy-saving equipment widely used in urban and rural power grid technology transformation projects as a new product.
