Cable Connector Tubes are electrical accessories that are used to securely connect or combine two power wires. Power cables are crimped on both sides of the ferrule for a solid connection. Electrolytic copper is used to make ferrules. Ferrules are available in two finishes: bare and tin plated. Divided into straight type (for the same cross-section of Al & Cu cables) and Reducing type (for different cross-sections of Al & Cu cables).

GTL copper cable connector
Material: E-CU A1-99.5%
Surface treatment: Bright
Product property: Due to the coupling effect when aluminum comes in contact with copper corrosion will happen in a short time currently the best solution is to use aluminum-copper bimetal connectors, A bimetal link should be used for joint the friction welding is well done and its aluminum barrel capped is filled with joint compound to avoid oxidization.
