Product Description
S13 type high overload power distribution transformer is one kind of
distribution product which can overload run under certain condition.
In rural areas,the average load rate is low;however,during Spring
Festival and busy period,the load will increase in short time and the
transformer will be overloaded easily.On the basis of normal temperature rise,high overload power distribution transformer can operate 6h under 1.5 times of rated capacity (in which load up for 3h and load down for 3h),operate 3h under 1.75 times of rated capacity (in which load up for 1.5h and load down for 1.5h)and operate Ih under 2.0 times of rated capacity and above overload operation camnot affect the normal lifetime of transformer.This product can not only guarantce the demand of long-term small load operation but also meet the short-time overload requirement.The cross section of iron core is multistage and D type yoke.And laser grooving cold-rolled grain oriented silicon steel sheet is adopted and the product is featured with low no-load loss and small noise ete.
