Abstract
A high temperature resistant insulated electrical conductor (100) is provided in which a electrostatically deposited layer (6) of fluorocarbon material is disposed about a fiberglass insulation layer (4) encompassing a stranded or solid electrical conductor (2). Layer (6) is surrounded by a layer (8) of fiberglass insulation which in turn is preferably encompassed by a braided layer (10) of fiberglass insulation which is preferably coated with a layer (2) of protective high service temperature material. Layer (6) is preferably sintered to provide a fused homogenous construction as is layer (12) when required.
Claims20
An insulated electrical conductor comprising an electrical conductor encompassed by at least one layer of fiberglass, an electrostatically deposited layer of fluorocarbon material disposed about the fiberglass layer, and at least one outer layer of fiberglass disposed about the layer of fluorocarbon material.
An insulated electrical conductor comprising an electrical conductor, a layer of fiberglass disposed contiguously about the conductor, an electrostatically deposited layer of fluorocarbon material disposed contiguously about the fiberglass layer and an outer layer of fiberglass disposed contiguously about the layer of fluorocarbon material.
A method for making an insulated electrical conductor comprising:
- providing an electrical conductor of indeterminate length;
- disposing a layer of fiberglass about the conductor;
- electrostatically depositing a layer of fluorocarbon material about the fiberglass layer;
- disposing an outer layer of fiberglass about the fluorocarbon layer;
- and sintering the fluorocarbon material.
A method of making an insulated electrical conductor comprising:
- providing an electrical conductor of indeterminate length;
- spiraling a layer of fiberglass filaments contiguously about the conductor;
- electrostatically depositing a contiguous layer of fluorocarbon material about the fiberglass layer;
- spiraling an outer layer of fiberglass filaments contiguously about the layer of fluorocarbon material;
- disposing a braided layer of fiberglass about the outer fiberglass layer;
- and sintering the fluorocarbon material.
