Paying attention to the quotation of transformer oil manufacturers will provide reference for customers to choose and purchase. The majority of consumers hope to purchase products with good quality and low price, which can play a better role in reliability. Naturally, it is the basis for seeking better services. Therefore, targeted selection will be necessary and achieve the desired results.
We understand the quotation level of transformer oil, which will provide guidance and reference for customers to make more accurate choices. Our better choice of products is very helpful to obtain better service opportunities, and then we can have a good effect in terms of reliability.
The average price is 350 barrels. The transformer oil standard of our country was formulated by imitating the Goster standard of the former Soviet Union (10121) and IEC296 standard in the 1960s. The products are divided into three grades according to the solidification point. They are 10 The solidification point test method itself comes from the former Soviet Union test method Goster standard (20287). Usually paraffin base oil is used to produce 10 #, intermediate base oil is used to produce 25 #, naphthenic base oil is used to produce 25 # and 45 # transformer oil.
When the solidification point of transformer oil is not higher than - 10 C (revised as inclination point - 7 in 1990), it is 10# transformer oil; when the solidification point is not higher than - 25 C (revised as inclination point - 22 in 1990), it is 25# transformer oil; when the solidification point is not higher than - 45 transformer oil.
Transformer oil usually uses paraffin base oil to produce 10 #, intermediate base oil to produce 25 #, naphthenic base oil to produce 25 # and 45 # transformer oil. Usually 10 # transformer oil is made of paraffin-based oil after KETONE-BENZENE dewaxing-solvent refining-clay refining, when the solidification point reaches below-10 #, it is used as -10 # transformer oil raw material; when intermediate or paraffin-based raw material is used after KETONE-BENZENE dewaxing-solvent refining-clay refining, the solidification point reaches below-25 #, it is used as 25 #.# Transformer oil; when naphthenic oil is used as transformer oil raw material, transformer oil raw material with solidification point below - 45 C can be directly obtained by atmospheric distillation without KETONE-BENZENE dewaxing.
Therefore, 45 # transformer oil can only be produced by Naphthenic alkyl oil. When using naphthenic alkyl oil to produce 25 # transformer oil, the solidification point of transformer oil obtained is usually from - 30 to - 45 C.
