Structure features

1. The combination of current, voltage, damping magnetic steel parts with pedestal, as well as with base parts adopts reinforced fastening, to ensure the parts in the meter can't move.

2. Strong magnetic property, magnetic bearing made of high stability material, the guiding part adopts import graphite bearing of self-lubrication and anti-abrasion and stainless steel axle pin of high strength that constitute long-life rotating element, so that the stability and long life of meter can be ensured.

3. Damping magnetic steel adopts alnico material, it has good temperature compensating characteristics.

4. The creeping needn't to be adjusted, can be finished by anti-creeping hole on the disc.

5. The voltage coils are imbedded or plastic sealed, it can withstand surge voltage more than 6kV.
