Product Description
- 产品描述
-
The 10kV and below S(Z)11, S(Z)11-M, and S13-M series oil-immersed transformers produced by our company are next-generation energy-saving products. They are widely used in power systems for 10kV and below lines, serving applications such as power transmission, transformation, distribution, power stations, power supply, lighting, and high- and low-voltage prefabricated substations.
Product Implementation Standard
GB 1094.1 "Power Transformers – Part 1: General Requirements"
GB 1094.2 "Power Transformers – Part 2: Temperature Rise"
GB 1094.3 "Power Transformers – Part 3: Insulation Levels, Insulation Tests and Air Clearances for External Insulation"
GB/T 6451 "Technical Parameters and Requirements for Three-Phase Oil-Immersed Power Transformers"
JB/T 10088 "Sound Level of Transformers Rated 6-220 kV"
GBT 25446 "Technical Parameters and Requirements for Oil-Immersed Amorphous Alloy Core Distribution Transformers"
Product Features
1. Employs corrugated-plate or plate-type radiator tanks with an aesthetically pleasing appearance.
2. A new suspension plate structure has been adopted, resolving the issue of the device body being “suspended in mid-air.”
3. Transformer oil is not exposed to the atmosphere, so there is no need for regular oil sample testing (in sealed systems).
4. Equipped with self-locking, anti-loosening nuts and featuring a non-core-hanging design, the unit’s body is tightly fitted to the oil tank, enabling it to withstand transportation vibrations and bumps.
5. The corrugated sheet not only has a cooling function but also a “breathing” function; its elasticity can compensate for changes in oil volume caused by temperature fluctuations.
6. No oil replacement is required throughout the normal service life, enhancing the safety and reliability of power grid operation.
