A cold-applied joint for a paper-insulated lead cable (PILC) including paper insulation impregnated with oil the joint comprising at least a first PILC having an inner conducting element that is conductingly secured to the inner conducting element of a further cable within a hollow interior of a deformable elastomeric sleeve 12 having secured on and encircling its exterior over the length of the said sleeve an in-use rigid member 13 that restrains expansion of the elastomeric sleeve resulting from expansion of oil in the paper insulation of the cable. The in-use rigid restraint layer 13 is preferably a moisture cured resin impregnated tape wound about the exterior of the elastomeric sleeve 12 which when cured forms a hardened outer layer. Item 11 is a mandrel which simulates a joint, in reality this would be a cable joint including a PILC. |
