Abstract
A cable assembly includes a conductor and a self-cleaning layer that surrounds the conductor and includes one or more of a photocatalyst and an electrocatalyst. Overhead high voltage electricity transmission lines are formed from these cable assemblies. Methods of reducing surface buildup on a cable are also provided.
Claims17
A cable assembly, comprising:
- a conductor;
- a self-cleaning layer surrounding the conductor, the self-cleaning layer comprising one or more of a photocatalyst and an electrocatalyst;
- and
- an intermediate layer surrounding the conductor and disposed between the conductor and the self-cleaning layer, the intermediate layer formed from an inorganic, non-photocatalytic material;
- and
- wherein the one or more of the photocatalyst and electrocatalyst are in a crystalline state and have an average particle size of 1 nm to 100 nm, and the cable assembly comprises a water contact angle smaller than a cable assembly without the self-cleaning layer when measured in accordance with ASTM D5725-99 (2008) after exposure to ultraviolet light for 60 minutes or more.
3 more elements
A cable assembly, comprising:
- a conductor;
- a self-cleaning layer surrounding the conductor, the self-cleaning layer comprising a first photocatalyst comprising titanium oxide;
- and
- an intermediate layer surrounding the conductor and disposed between the conductor and the self-cleaning layer, the intermediate layer comprising from 10% to 35%, by weight, of one or more of a second photocatalyst and an electrocatalyst;
- wherein the titanium oxide is in a crystalline state and has an average particle size of 10 nm to 50 nm, and the cable assembly comprises a water contact angle smaller than a cable assembly without the self-cleaning layer when measured in accordance with ASTM D5725-99 (2008) after exposure to ultraviolet light for 60 minutes or more.
2 more elements
A cable assembly, comprising:
- a conductor;
- and
- a self-cleaning layer surrounding the conductor as the outermost layer of the cable assembly, the self-cleaning layer comprising one or more of a photocatalyst and an electrocatalyst and being free of polymer;
- and
- wherein the one or more of the photocatalyst and electrocatalyst are in a crystalline state and have an average particle size of 1 nm to 100 nm, and the cable assembly comprises a water contact angle smaller than a cable assembly without the self-cleaning layer when measured in accordance with ASTM D5725-99 (2008) after exposure to ultraviolet light for 60 minutes or more.
