ABSTRACT:
Gas pressurized electrical cables, having a portion of an outer sheath removed for repair or splicing, are sealed while under pressure by providing at the exposed cable portion a gas pressure escape vent having a vent opening of area less than that of the cable exposed portion. Sealant tape is wrapped around the exposed cable portion and the vent exterior effectively sealing the entire exposed cable portion with the exception of the vent opening through which the gas escapes while such sealant tape is applied. The vent opening, being smaller than the original exposed cable portion, is readily sealably closed as by suitably plugging such vent opening and covering same with a sealant material.
