What do the various parts of SCB11 transformer represent and how much does a dry type transformer cost?
Q: What does each part of the SCB11 transformer mean?
Answer: First of all, this is a model of dry type transformer. S represents three-phase and three-phase winding; C refers to resin insulation, which is the origin of the name for dry type transformers; B represents low-voltage foil winding; The number 11 is the performance level code of the transformer. The following parameters are the rated capacity and voltage level of the transformer.
Dry type transformers are generally used indoors, while dry type transformers used outdoors need to be equipped with metal shells, etc. The price of dry type transformers is quoted based on specific parameters, such as capacity, voltage, etc. Dry type transformers have capacities ranging from 30kva to 3150kva, and prices range from 40000 to 120000 yuan. Additionally, each manufacturer of dry transformers with the same property is different.
