Claim 3

The cable of claim 1 wherein said inner layer and outer layer are co-extruded onto a non-jacketed cable.

Claim 4

The cable of claim 1 wherein said inner layer is an indoor or an outdoor rated plastic material and said outer layer is an outdoor rated plastic material.

Claim 5

The cable of claim 1 wherein said inner layer is an indoor or outdoor rated flexible polyvinylchloride having a temperature rating of at least about 60° C. at a 0.030 inch thickness and a voltage rating of 300 volts.

Claim 6

The cable of claim 1 wherein said outer layer is a flexible matte finish type polyvinylchloride with a temperature rating of less than about 105° C. and a thickness range of about 0.005 inches to about 0.008 inches and, in conjunction with the inner layer, a voltage rating of 300 volts.

Claim 7

A cable for use in an indoor and outdoor electrical system comprising: a core which comprises a transmission medium, said transmission medium being an insulated metallic or optical fiber conductor; a thermoplastic jacket which encloses said core and transmission medium, said jacket having an inner layer and an outer layer, said inner layer being inseparable from and integrally formed with said outer layer, said inner layer being an indoor or an outdoor rated flexible polyvinylchloride having a temperature rating of at least about 60° C. at a 0.030 inch thickness and a voltage rating of 300 volts, and said inner layer being from about 0.020 inches to about 0.065 inches thick and said outer layer being from about 0.005 to about 0.008 inches thick.

Claim 8

A cable for use in an indoor and outdoor electrical system comprising: a core which comprises a transmission medium, said transmission medium being an insulated metallic or optical fiber conductor; a thermoplastic jacket which encloses said core and transmission medium, said jacket having an inner layer and an outer layer, said inner layer being inseparable from and integrally formed with said outer layer, said inner layer being an indoor or an outdoor rated flexible polyvinylchloride having a temperature rating of at least about 60° C. at a 0.030 inch thickness and a voltage rating of 300 volts, and said inner layer being from about 0.020 inches to about 0.065 inches thick and said outer layer being from about 0.005 to about 0.008 inches thick.

Claim 9

The cable of claim 6 wherein said inner layer and outer layer have as their main ingredient the same plastic material.

Claim 10

A thermoplastic cable for use in an indoor and outdoor electrical system comprising: a core which comprises an insulated transmission medium, said transmission medium having at least two metallic conductors or optical fibers each coated with insulating polyvinylchloride; a filler surrounding said transmission medium, said filler being selected from polyamide fibers, jute fibers, cotton fibers or polypropylene fibers; a separating layer wrapped around said filler and insulated conductors; and a flexible multi-layer polyvinylchloride jacket which encloses said core, said jacket having an inner layer and an outer layer, said inner and outer layer co-extruded onto said core and subsequently fed into a single set of forming dies such that they are inseparable from and integrally formed with one another, said inner layer being a flexible polyvinylchloride composition having a thickness of at least 0.025 inches and an indoor and outdoor electrical rating with temperature rating of at least about 60° C. when having a 0.030 inch thickness and a voltage rating of 300 volts, said outer layer being a flexible polyvinylchloride composition with a matte type finish and a thickness of at least 0.005 inches and a temperature rating of less than 105° C., and said inner layer having an equal or higher tensile strength than said outer layer.

Claim 11

A thermoplastic cable for use in an indoor and outdoor electrical system comprising: a core which comprises an insulated transmission medium, said transmission medium having at least two metallic conductors or optical fibers each coated with insulating polyvinylchloride; a filler surrounding said transmission medium, said filler being selected from polyamide fibers, jute fibers, cotton fibers or polypropylene fibers; a separating layer wrapped around said filler and insulated conductors; and a flexible multi-layer polyvinylchloride jacket which encloses said core, said jacket having an inner layer and an outer layer, said inner and outer layer co-extruded onto said core and subsequently fed into a single set of forming dies such that they are inseparable from and integrally formed with one another, said inner layer being a flexible polyvinylchloride composition having a thickness of at least 0.025 inches and an indoor and outdoor electrical rating with temperature rating of at least about 60° C. when having a 0.030 inch thickness and a voltage rating of 300 volts, said outer layer being a flexible polyvinylchloride composition with a matte type finish and a thickness of at least 0.005 inches and a temperature rating of less than 105° C., and said inner layer having an equal or higher tensile strength than said outer layer.
