Compression Type Al-Cu Terminal Connector

Compression Type Al-Cu Terminal Connector

The terminal connector is used for the connection among bus-bar, downlead, and electrical equipment (such as transformers, circuit breakers, transformers, isolating switches, etc.). The compression Al-Cu terminal connector adopts hydraulic construction.

Usage scenarios

Substation system

Technical features

  1. The resistance at both ends of the conductor joint of compression type Al-Cu terminal connector shall not be greater than the resistance of an equivalent length of the conductor;
  2. The temperature rise at the conductor’s joint shall not be greater than the temperature rise of the conductor;
  3. The current carrying capacity of the terminal connector shall not be less than the carrying capacity of the down lead;
  4. The current carrying capacity of the terminal connector shall not be less than the carrying capacity of the down lead.
