Specifications and Product Details:

  • Construction
  • Meter case
  • It meets the protection requirements set by protection class IP53 of IEC62053-21. The series types of cases and terminal covers are available.
  • Terminals
  • The connection terminals are made for nickel-plated brass with features of high mechanical Strength, good conductivity and corrosion-resistance.
  • Terminal block
  • The terminal block is injection molded of heat-and fire-resistant Bakelite . The voltage test link can be located inside or outside of the meter case.
  • Driving system
  • The driving system employs three single electromagnet elements, all of which are mounted on the meter frame with three screws. Each electromagnet element consists of voltage element, current element and connection board. In addition, the voltage electromagnet has low load and inductive load adjustment mechanisms. The current element employs a simple and reliable load curve compensation mechanism to ensure the flat characteristic curve.
  • Rotor
  • The rotor shaft is turned of high strength aluminum alloy. The upper end of the shaft is pressed with a worm which is made of thermoplastic, and the lower end is embedded with a graphite bearing which is self-lubricative and friction-resistant to ensure long service life of the meter.
  • Braking element
  • The magnet is made of AINiCo5 alloy and designed as U-shaped so that the effect of short-time over currents upon the magnet is negligible. A temperature compensation plate, made of a special alloy, is embedded in the braking magnet. The rotor speed can be adjusted largely and continuously by rotating the whole magnet.
  • Frame
  • The frame is die-casted by high quality Si Al alloy. Its structure is designed as W-shaped of stable property to avoid distortion, and its surface is treated with chromate to achieve reliable and durable coating against oxidation.
  • Upper bearing
  • The pin is made of abrasion-proof stainless steel, and pressed into the brass sleeve. It is the rotor guide and runs in the plastic worm of the rotor.
  • Lower bearing
  • The magnetic suspension bearing consists of two ring shaped magnets, a guide pin and a bearing base. The pin made of stainless steel runs in the graphite sleeve of the rotor. No lubrication is needed.
  • Register
  • The cyclometer type register consists of six drums. It can be read directly. The drum is made of polycarbonate. The framework is embedded with a high-strength self-lubricating plastic bearing. No lubrication of bearings is needed during the service life.
