4. Expose the Conductors to half the length of the Connectors and fit using a suitable Crimp tool.
Note:- Mechanical Shearbolt Connectors can be used, but user should advise as Insulation Tubes will need to be
increased in size.
5. Position the Tubes centrally over the Connectors and shrink from the centre to one end at a time. Keep the flame
on the move to ensure an even wall thickness. Sealants will be visible at Tube ends once fully shrunk.
Note:- Copper Sock/Mesh is
supplied instead of Cages for
