Single Phase Mechnical Energy Meter DD28

الوصف

1.General
DD*8 single phase KWH hour meter is a kind of induction meter which is applicable to measure .
the rated frequency *0Hz and power loss in electrified wire netting.All technical targets are completely conformed to National standard GB/T*********4 and lntermational standard IEC**1.
 
2.Structure feature:
The meter has separable electromagnet and the bearing has four kinds;single-jewel,magnetic thrust and magnetic floating.The case has three kinds;aluminum,plastic and glass.The die-casting frame is alloy aluminum with excellent mechanical strength.
