Generally, cable lugs and ferrules are fixed to the cables and wires by inserting the conductors into the “barrel” (tube) of the device and then “crimping” (squeezing) the “barrel” onto the conductors to form a secure mechanical and electrical joint.
They are manufactured in a number of different designs and made from high conductivity copper (tin plated) to suit various cables and wires.
THE MAIN OPTIONS AVAILABLE ARE:
- Heavy duty copper lugs and ferrules for use with copper cables and wires in specialised applications, such as medium and high voltage electrical systems.
- Light duty copper lugs and connectors for use with copper cables and wires, in general industrial, commercial and domestic applications.
- For terminating of cables and wires in electrical circuit systems and equipment.
- Joining of cables and wires in electrical reticulation systems and equipment.
- Cross sectional area of the conductor to be terminated or joined.
- Form of conductor, e. solid, stranded, compacted or multi-stranded.
- Size of securing bolt or stud.
FEATURES AND BENEFITS:
- Manufactured from high conductivity copper which is tin plated to prevent corrosion.
- Suitable for use in a variety of applications, with various copper cable and wire types, provided the correct size is selected and the relevant “crimping” methods are used.
DO’s & DON’Ts:
- Take care to assess the application and installation requirements prior to specifying a cable lug or ferrule.
- Ensure that lug size selected matches thecross-sectional area of the cable wire’s conductors.
- Use a proper crimping tool.
- Never cut conductors strands off a cable or wire in order to fit a smaller lug or ferrule.
