660v low voltage transformer

Series LMK 1,2-0.66a(bh,MSQ,SDH) current transformer is mainly used for power system with rated frquency 50Hz and rated voltage under 0.66kv to measure electric energy,current and protec relay .

1.with full complete of specification and wide range of application,suitable for any primary current from 5A to 5000A or 1A to 4000A( including non-standard specification ).the secondary current has two types:5A and 1A,the different window types can match with different bus-bars and cables

2.With nice appearance and reasonable design

3.Compared to same line of products,this producet is more compact.less weight ,larger capacity ,higher accuracy and more compliance with the standard of electria-control design.

4.With advanced technology and excellent performance

5.With features such safety,flame rerardant,without static electricity in the surface,the case is mage of imported flame retardant material by high-pressure casting ,so it has feature of high strengh and resisting flame

6.With features of firmness,durability,ful-sel,high temperature resistant,moisture proof,shock proof ,anti-saltspray and prevent from electric-theft.

The 660v low voltage transformerare designed for outdoor service conditions. The transformers are u sed in single-phase electric systems and rated frequency of 50/60 Hz. The products are designed in accordance with Standards IEC60044-2 and GB12072006. The products are typically used in electric energy metering, voltage controlling and relay protection applications.
