A step-down transformer lowers voltage from primary to secondary (has more primary turns than secondary turns). It is also known as step-down insulation transformers. It converts low-voltage, high-current power into low-voltage, high-current power as a step-down unit. It can be used in a lot of electrical systems and transmission lines. A larger gauge wire is used in the secondary winding for this stepdown insulation transformer because of the increased current. A primary winding on an isolation transformer, which doesn’t have to conduct much current, can have a smaller gauge.We can make this step down transformer under our clients’ budget and to their specifications.
