Cable lugs and ferrules are connecting devices used primarily for terminating and joining cable and wire conductors in electrical installations and equipment.
In general, lugs and ferrules are fixed to the cables and wires by inserting the conductor(s) into the “barrel” (tube) of the device and then “crimping” (squeezing) the barrel on to the conductor(s) to form a secure mechanical and electrical joint.
The devices are manufactured in a number of different designs and made from high conductivity copper (tin plated) or aluminium to suit various cable and wire types and specific installation requirements.
Careful consideration must be given to selecting the right product for an application.
The main options available are:
- Standard duty copper lugs and ferrules for use with copper cables and wires in general industrial, commercial and domestic applications.
- Heavy duty copper lugs and ferrules for use with copper cables and wires in specialised applications such as medium and high voltage electrical reticulation systems.
- Copper and aluminium shear lugs for applications where crimping equipment cannot be used.
- Bi-metal lugs for mating copper and aluminium conductors to prevent dissimilar metal corrosion.
