Pilot Cable Joint
The pilot cable joint pictured below is twisted and tipped type.
The cable jointer had to improvise the installation due to the absence of a type tested manufactured cable joint which caters for this specific LV cable configuration – it would be usual to use a resin cable joint for standard straight jointing of pilot cables up to 100 pair.
Pictured jointed is a 30 core PILC armoured cable to 2 x 7 pair jelly filled steel wire armoured (SWA) telephone cables with PE insulation.
The Jointer used a small LV branch joint shell as a mould for resin which provided both mechanical and moisture protection. The connection of the cable cores was by soldering and then small lengths of heatshrink tubing were used to insulate the cable joint.
The Jointer established earth continuity of the lead sheath to wire armours on the plastic cable with constant force roll springs and tinned copper braid – to remove traces of petroleum jelly from the pilot cables 3M recommend use of their cable jointers and cleaning wipes.
