Our common dry change models SCB10, SCB11, and SCB13 are products that belong to the old national standard of GB20052-2013. The corresponding energy efficiency levels of the products are three-level energy efficiency, two-level energy efficiency and first-level energy efficiency.
my country will implement a new energy efficiency standard on June 1, 2021, namely GB20052-2020, and the upgraded models are SCB12, SCB14, and SCB18. The energy efficiency grades corresponding to the products are three-level energy efficiency, two-level energy efficiency, and first-level energy efficiency.
Compared with the old national standard, the new national standard is mainly different in loss, that is, no-load loss and load loss. Compared with SCB10, SCB12 has an average no-load loss reduction of 20%, and load loss remains unchanged. Compared with SCB11, SCB14 has an average no-load loss reduction of 15%, and an average load loss reduction of 10%. Compared with SCB13, SCB18 has no-load loss The average decrease is 20%, and the load loss remains unchanged. The implementation of the new national standard is the need for green, energy-saving and sustainable development in the new era. For outdated and high-energy-consuming transformers, it is only a matter of time before they are eliminated, so before purchasing dry-type transformers, please confirm the energy consumption standards and energy efficiency levels.
Many customers will consider aluminum core transformers because of economic considerations. In fact, aluminum core dry-type transformers are not uncommon. The model of aluminum core dry-type transformers is exactly the same as that of copper core dry-type transformers, except that the copper core winding is The aluminum core coil is wound, and the rest of the materials are exactly the same. The loss parameters of the dry-type transformer are the same as those of the copper core transformer, but usually an “L” is added to the nameplate of the aluminum core dry-type transformer to show the difference. core dry-type transformer.
The performance parameters of the two (no-load loss, load loss, impedance, temperature rise, noise level) follow the unified standard and fully meet the audit requirements of the State Grid, but the price of the aluminum core dry-type transformer is lower than that of the copper core transformer of the same type The discount is about 30%, so many customers, for the sake of economy, we suggest that they can choose aluminum core dry-type transformers, which can not only meet the demand for transformers, but also fully meet the country’s rigid requirements for the power industry.
