Application;
Single-phase kilowatt-hour meter in long life service series has the features of novel design, rational structure, stable performance, and over 25 years service. It¡¯s technique performance is completely conform to the stipulated requirement of National Standard GB/T15283-94 and International Standard IEC60521.
Structure and features:
Register is polyformaldehyde gears with best contact adopted for good resistance to abrasion, damping magnet and aluminum alloy frame die casting together for more mechanical stability, the coil of electronic component made of higher grade silicon steel with high-punch pressing it and sheet keeping compatibility of electric character. Voltage coil covered with flexible heat shrinkable cross linked polyolefin tubing for heat resistance. Passing the shock test. Frictionless magnetic suspending bearing, lubricant needed in the long life service.
