LZZW-24 Outdoor Current Transformer

Introduce:

The model belongs to outdoor dry type cycloaliphatic epoxy current transformer. It is widely used in outdoor and Weather: Temperature can be from -25℃to 40℃, Relative humidity can be up to 95% , and altitude can be Up to 1000m. Used for current measurement and energy metering , for power systems with voltage of 24kV systems, and a rated frequency of 50Hz.

Feature:

  1. The voltage transformer is hot vacuum cast in an insulating resin, to achieve a discharge free high voltage insulation. It is designed as a whole with umbrella skirt structure to avoid the possibility of water accumulation on the product.
  2. The transformer will be suitable for horizontal installation on a steel structure;
  3. The secondary junction box on the transformer is not removable, and sealing protection level reaches IP55. The secondary junction box has a lead seal anti-theft function. The outlet hole has M32 connectors side.
  4. Ground terminals of threaded bolt type M12 stainless steel bolts.
  5. All parts and components of the current transformer will be resistant to atmospheric corrosion.
  6. All terminals will be clearly marked.
