Abstract
A technique and system for insulating conductors is provided in which insulating tubes are formed by winding insulating tape on a mandrel, with two or more layers of tape being wound in the same or opposite helical directions. The layers are bonded to one another and multiple tubes are formed in a series which can be nestingly assembled. The tubes are selected based upon the insulation rating desired and the size of a conductor. The tubes are assembled on the conductor and bonded to one another and to the conductor.
Claims32
A method for insulating an electrical conductor, the method comprising:
- assembling at least two tubular insulators by inserting a first insulator within a second insulator;
- positioning the assembled insulators on an electrical conductor;
- repositioning the assembled insulators and the electrical conductor into their final position allowing the assembled insulators to displace relative to one another and to the conductor during the repositioning;
- and
- then bonding the first and second insulators to one another and to the conductor.
