Abstract
A conduit end is sealed around one or more than one insulated conductor by using a chamber (4) having a peripheral wall, a base with an opening through it communicating with the conduit (2) and an opening opposite the base. The conductor(s) (3) extend through both openings; a pre-formed annular body of a setting resin composition (8) is inserted while in a pasty or viscous condition into the chamber to encircle the conductor or conductors. Axial pressure is then applied to the still pasty or viscous annular body to cause it to flow and form a sealing body in peripherally continuous contact with the chamber and with the, or each, insulated conductor, after which the resin composition sets. A kit for use in the method is also claimed.
Claims9
A kit for sealing a conduit end around at least one insulated conductor comprising:
- a chamber having a peripheral wall, a base with an opening through it for communicating with said conduit and an opening opposite said base;
- a supply of a setting resin compound;
- a carrier for holding a preformed annular body of the compound, in a condition capable of but offering resistance to flow, during insertion into said chamber:
- and means for applying pressure to said annular body when in said chamber to cause it to flow and to produce a sealing body in peripherally continuous contact with said chamber and with said at least one insulated conductor.
A method of sealing a conduit end around a plurality of insulated conductors comprising:
- providing a chamber having a peripheral wall, a base with an opening through it communicating with said conduit, and an opening opposite said base, said conductors extending through both openings;
- inserting a pellet of a setting resin composition, in a condition capable of but offering resistance to flow, between the conductors in the chamber;
- preforming an annular body of a setting resin composition, in a condition capable of but offering resistance to flow, and inserting it in that condition into said chamber to encircle said conductors;
- and applying axial pressure to said annular body while still in said condition to cause it to flow and form a sealing body in peripherally continuous contact with said chamber and with each of said insulated conductors;
- and the resin composition thereafter setting.
