Repairing cable installations

A power cable installation is repaired using a precut length 6 (about 3m for an 11kV distribution cable) of replacement cable each end of which has already been prepared by cutting back to expose end portions of its individual cores and by fitting stress control means and crutch sealing means thereto. Preferably at least the end portions are enclosed for protection in storage and transit. In the Figure, showing only one end of the damaged cable 1, a corresponding length of the cable is cut out and discarded and the two remaining cut ends of the damaged cable are prepared for jointing and jointed to the already prepared ends of the precut short length brought to site, the electrical connections being covered stress control sleeves 12. Since two cable ends, instead of four, are prepared for jointing at the site of the damage, around two hours' site work by a two-man jointing team is saved.
