Claims
- 1. A method of insulating an energy transmission member comprising the steps of:
- creating a insulated transmission member by;
- wrapping a glass fiber yarn around an energy transmission member;
- impregnating the yarn with a metered amount of a first mixture; and
- preventing the first mixture from reaching the inner periphery of the yarn and contacting the energy transmission member.
- 2. A method as recited in claim 1, wherein the energy transmission member is a bare electric conductor.
- 3. A method as recited in claim 1, wherein there is a coating step in which a second mixture is coated around the impregnated yarn.
- 4. A method as recited in claim 3, wherein said mixtures used in both the impregnating and coating steps are silicone based compounds.
- 5. A method as recited in claim 4, wherein the second mixture includes clay and alumina trihydrate.
- 6. An insulated transmission member comprising:
- at least one energy transmission member;
- glass fiber yarn wrapped around said energy transmission member, said glass fiber yarn having inner periphery that contacts said transmission member;
- said glass fiber yarn being impregnated by a first silicone mixture, said first silicone mixture being impregnated into the outer periphery of said glass fiber yarn, said inner periphery of said glass fiber yarn being unimpregnated such that said first silicone mixture does not contact said transmission member; and
- a second silicone mixture coating disposed around the outer periphery of said glass fiber yarn.
- 7. An insulated energy transmission member as recited in claim 6 wherein said energy transmission member comprises a bare electric conductor.
- 8. An insulated energy transmission member as recited in claim 6 wherein there are several of said energy transmission members, each having an individual insulation within said glass fiber yarn.
- 9. An insulated energy transmission member as recited in claim 6, wherein said second silicone mixture includes clay and alumina trihydrate.
