 JLSZYo-35W voltage transformer

Description and meaning of model

This type of voltage,current combined transformer (also known as energy metering box)for the exchange of 50Hz,rated voltage of 10kV three-phase power lines for active and reactive energy metering.Apply to rural outdoor substation.Also be used for the small change of the industrial enterpries,power distribution.This product can replace the JLS-10 oil-immersed power metering box.

Characteristic of structure

The combined transformer for outdoor epoxy casting,all closed,the pillar structure.Outdoor epoxy casting,the product has the arc resistance.aging resistance,long life  ,maintenance-free characteristics .This product consists of two single-phase full insulation voltage transformer formed a "V"-shaped connection,two current transformer are connected in series A and C phase.And current transformer secondary winding with a tap can be obtained with different current ratio.
