Terminals are made of brass having two screws for tightening the external cables.
1.4 Terminal block cover
ABS cover ,big metal cover ,Extended steel cover-rubber underside the cover ensures insulation between the cover and the terminal block. Access is available at each side of the terminal cover for external cables.
2. Driving element Current electromagnet
The overload compensating set mounted on the laminated silicon-steel core assures the excellent load curve performance. Voltage electromagnet The design of voltage electromagnet permits to withstand the impulse voltage of 6kV.
3. Braking element
Braking element is made of mono pole magnet. Its adjustment range conforms to requirements of IEC62053-21
4. Frame
The meter frame is made of aluminum alloy with sufficient strength. It is painted for effective protection against corrosion.
5. Moving element
Worm gear on the rotor shaft is made of brass or optionally plastic one.
Anti-creeping pin is fitted to the rotor shaft to prevent running with no-load.
Anti-reverse device can be mounted in the meter if it is required.
Upper bearing
With excellent friction resistant property, the upper bearing pin is of polished stainless steel to guide the rotating of the disc.
Lower bearing(optional)
Double jewel bearing, Magnetic bearing with metal enclosure
Magnetic bearing with transparent enclosure-the bearing enclosure is made of transparent polycarbonate.
6. Register
The register is of cyclometer type, with frame made of aluminum alloy. Digit drums are made of polycarbonate, UV radiation resistant. The register is fixed on the meter frame by two screws. It is adjustable to assure good mesh of worm with the rotor shaft. Unidirectional register is available.
7. Name plate
Printing ink used for name plate is UV radiation resistant one.
8. Sealing
Meter cover and terminal cover can be sealed separately. Seal and sealing wire can be made according to requirements of customers.
