CONNEX Transformer Socket, straight, Size 1, up to 24 kV


  • Socket for mounting into local grid transformers instead of DIN porcelain bushings on medium-voltage side
  • Insulating medium: oil (max. operating temperature: 110°C)
  • Attention: With XLPE-insulated cable the max. temperature of the conductor must not be higher than 90°C.


  • Testing of transformer in factory due to short time amount for plugging the accessories
  • Assembly time is significantly reduced and safe assembling guaranteed
  • Touch-proof and maintenance-free
  • Not offshore-proof
