Abstract

A cable surround material for a cable of an electricity transmission system comprising a mixture of: an additive containing carbon; sand; and cement, wherein the material comprises, by weight, approximately 60-80% carbon containing additive, approximately 5-10% cement, and a remainder of sand.

Claims

1. A cable surround material for a cable of an electricity transmission system comprising a mixture of:

an additive containing carbon;

sand; and

cement, wherein the material comprises, by weight, approximately 60-80% carbon containing additive, approximately 5-10% cement, and a remainder of sand.

2. A cable surround material according to claim 1, wherein the material comprises, by weight, approximately, 67% carbon containing additive, approximately 7% cement, and approximately 26% sand.

3. A cable surround material according to claim 1, wherein the carbon containing additive comprises greater than approximately 90% by weight carbon.

4. A cable surround material according to claim 3, wherein the carbon containing additive comprises about 96% by weight carbon.

5. A cable surround material according to claim 1, wherein the cement is Portland cement.

6. A cable surround material according to claim 1, wherein the additive contains the carbon family element or a key ingredient or constituent in crystalline or amorphous form, or both.

7. A cable surround material according to claim 1, wherein the additive contains the carbon family element or a key ingredient or constituent in a granular form of varying sizes.

8. A method of mixing a cable surround material according to any preceding claim, the method comprising:

providing the carbon containing additive;

providing the cement;

providing the sand; and

mixing the carbon containing additive, sand, and cement to form the cable surround material.

9. A method of laying a cable comprising:

at least partially surrounding a cable in a cable surround material comprising a mixture of;

an additive containing carbon;

sand; and

cement,

wherein the material comprises, by weight, approximately 60-80% carbon containing additive, approximately 5-10% cement, and a remainder of sand.

10. A method according to claim 9 further comprising mixing the cable surround material by:

providing the carbon containing additive;

providing the cement;

providing the sand; and

mixing the carbon containing additive, sand, and cement to form the cable surround material.

11. A method according to claim 9, further comprising:

providing the cable, wherein the cable is for transmitting high voltage electricity in an electricity transmission system.

12. A cable arrangement comprising:

a cable at least partially surrounded by a cable surround material comprising a mixture of;

an additive containing carbon;

sand; and

cement,

wherein the material comprises, by weight, approximately 60-80% carbon containing additive, approximately 5-10% cement, and a remainder of sand.

13. A cable arrangement according to claim 12, wherein the cable is for transmitting high voltage electricity in an electricity transmission system.

14. An electricity transmission system comprising:

a cable arrangement comprising;

a cable at least partially surrounded by a cable surround material comprising a mixture of;

an additive containing carbon;

sand; and

cement,

wherein the material comprises, by weight, approximately 60-80% carbon containing additive, approximately 5-10% cement, and a remainder of sand.

15. An electricity transmission system according to claim 14, further comprising at least one cable sealing end compound, joint bay, stop joint, or fluid cooling system.
