CONNEX Socket, Size 3, for Transformers, up to 52 kV, up to -40°C

Application:

  • Socket for mounting into transformers, breaker units, condensers, joints and other oil-insulated equipment
  • 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.

Characteristics:

  • 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, maintenance-free and floodable (IP67)
