• 0.5KV Low Voltage Single Phase Residual Current Transformer For Indoor Switchgear

  This LXK series current transformer is indoor type, applied to rated voltage 0.5kV, rated frequency 50-60Hz in the power system, used for the zero sequence overcurrent protection of power system, high voltage three-phase AC generator and motor. The outside diameter of transmission cable is not more than 120MM. This current transformer is divided into two halves, and the resin is poured into a semicircle, then connected with clamps. When installed, the transformer can be divided into two halves, then combined into a whole. The installation is very convenient.

  Operating Condition
  1. Altiude is no more than 1000m.

  2. The maximum change of surrouding temperature is no more than -30°C~+40°C.

  3. Universal product is only used in the area with less than 85% relative humidity.

  4. Installation field had no serious effect transformer insulated, steam, chemical deposition, dust foul and other explosive and corrosive medium, and the field without serious shake and bump.
