Through the analysis on the results of no-load test and the derivation of the related formulas, the variable characteristics of no-load loss and noise of SC9 series resin-cast dry-type transformer are summarized when its working voltage is raised up to 10%.
The epoxy cast dry-type transformers high-and-low coil is pressurized by araldite which is good in performance, anti-cracking, high temperature-proof and has long life time. Its anti-flaming, damp-proof and wont pollute the environment.
