Compaction of electrical insulation for joining insulated conductors

摘要

A method for coupling ends of two insulated conductors includes coupling a core of a first insulated conductor to a core of a second insulated conductor. Exposed portions of the cores are located inside a box with an open top. Electrically insulating powder material is placed into the box and a first plunger is inserted through the open top of the box to compact the powder material. Additional electrically insulating powder material is placed into the box and a second plunger is inserted through the open top of the box to compact the powder material into compacted powder material that surrounds the exposed portions of the cores. The compacted powder material is formed into a substantially cylindrical shape. A sleeve is placed over the compacted powder material and coupling the sleeve to the jackets of the insulated conductors.

1. A method for coupling ends of two insulated conductors, comprising:
coupling an end portion of a core of a first insulated conductor to an end portion of a core of a second insulated conductor, wherein at least a part of the end portions of the cores are at least partially exposed; locating the exposed portions of the cores inside a box with an open top, wherein an end portion of a jacket of the first insulated conductor is located in an opening on a first side of the box and an end portion of a jacket of the second insulated conductor is located in an opening on a second side of the box, the second side of the box being opposite the first side of the box; placing electrically insulating powder material into the box; inserting a first plunger through the open top of the box; applying a force to the first plunger to compact the powder material, wherein the powder material is compacted into compacted powder material that at least partially surrounds a part of the exposed portions of the cores, and wherein the part of the exposed portions of the cores surrounded by compacted powder material after compaction with the first plunger comprises about half of the exposed portions; placing additional electrically insulating powder material into the box; inserting a second plunger through the open top of the box; applying a force to the second plunger to compact the powder material, wherein the powder material is compacted into compacted powder material that surrounds the exposed portions of the cores; forming the compacted powder material into a cylindrical shape with an outside diameter similar to an outside diameter of at least one of the insulated conductors; and placing a sleeve over the compacted powder material and coupling the sleeve to the jackets of the insulated conductors.
