Abstract

The invention provides a method of forming a seal () between and around conductors (A,B andC) of an electrical power cable (), and has particular application as a safety measure in potentially explosive applications. The method includes passing the conductors (A,B andC) through an opening in a body () so as to define a cavity within the body () between and around the conductors (A,B andC); introducing an absorbent material () into the cavity; introducing a liquid settable material () into the cavity; and allowing the settable material () to be absorbed by the absorbent material () and to set thereby to seal the cavity between and around the conductors (A,B andC).
