Abstract

There is provided an electrically insulating cap according to any one of the appended claims. The cap comprises a tube (10) having a tube radius, an opening at a first end (12) of the tube for receiving electrical wires, and a joint (16) between two opposing sides of the tube within an interior of the tube. The joint blocks the tube at a point along a length of the tube to prevent the electrical wires from entering beyond a fixed distance into the tube. The joint is spaced away from a second end (14) of the tube by a standoff distance (20), the second end of the tube being opposite the first end of the tube. The standoff distance (20) is greater than the radius (22) of the tube and less than five times the radius of the tube. The tube is formed of an outer tube of a non heat shrinkable material around an inner tube of a heat shrinkable material.

Abstract

An electrical insulating cap formation (1) comprising a strip of material (2) and one or more electrical insulating caps (3) each comprising a tubular section (4) and a closed end (5) section, in which the one or more electrical insulating caps are carried on the strip of material by their end sections, in which the strip of material comprises a wing portion (6) which extends over at least a part of the tubular sections of the one or more electrical insulating caps, and in which the strip of material is formed such that an outer edge (7) of said wing portion is spaced apart from the tubular sections of the one or more electrical insulating caps.

Abstract

A shrinkable wrapping material comprising an inner layer and an outer layer connected to one another, in which the inner layer comprises greater permanent shrinkage characteristics than the outer layer, in which the inner layer is shrunk in one direction to a pre-determined degree such that the shrinkable wrapping material is formed into a roll, in which the inner layer and outer layer are resilient such that the roll is unrollable, and in which the inner layer is further shrinkable.
