Abstract
The present invention relates to a device comprising a cable and/or a cable accessory, said cable and/or said cable accessory comprising at least one composite layer obtained from a composite composition based on at least one cellulose derivative, at least one organic compound having a boiling point or a decomposition temperature above about 100° C. and at least one cement composition selected from an aluminosilicate geopolymer composition and a magnesium-based composition, as well as to a method of manufacturing such a device.
Claims18
A device comprising:
- a power cable and/or a telecommunication cable, and/or
- an accessory for a power cable and/or a telecommunication cable,
- wherein said cable and/or said cable accessory comprise at least one composite layer obtained from a composite composition comprising at least one organic compound having a boiling point or a decomposition temperature above 100° C., at least one cellulose derivative, and at least one cement composition selected from the group consisting of
- an aluminosilicate geopolymer composition, and a magnesium-based composition, said magnesium-based composition comprising a magnesium silicate, an alkaline silicate, water, and an alkaline base, and
- wherein the organic compound represents from 10 to 70 wt %, relative to the total weight of the composite composition.
A composite composition for a composite layer of a power cable and/or a telecommunication cable, or an accessory for a power cable and/or a telecommunication, said composite composition comprising:
- at least one organic compound having a boiling point or a decomposition temperature above 100° C.,
- at least one cellulose derivative, and
- at least one cement composition selected from the group consisting of;
- an aluminosilicate geopolymer composition and
- a magnesium-based composition, said magnesium-based composition comprising a magnesium silicate, an alkaline silicate, water, and an alkaline base, and
- wherein the organic compound represents from 10 to 70 wt %, relative to the total weight of the composite composition.
A device comprising a power cable and/or a telecommunication cable, and/or an accessory for a power cable and/or a telecommunication cable, wherein said cable and/or said cable accessory comprise at least one composite layer obtained from a composite composition comprising at least one organic compound having a boiling point or a decomposition temperature above 100° C., at least one cellulose derivative, and at least one cement composition selected in the group consisting of:
- an aluminosilicate geopolymer composition, and
- a magnesium-based composition, said magnesium-based composition comprising a magnesium silicate, an alkaline silicate, water, and an alkaline base, and
- wherein the composite composition further comprises an expanded carbon-containing material.
A device comprising a power cable and/or a telecommunication cable, and/or an accessory for a power cable and/or a telecommunication cable, wherein said cable and/or said cable accessory comprise at least one composite layer obtained from a composite composition comprising at least one organic compound having a boiling point or a decomposition temperature above 100° C., at least one cellulose derivative, and at least one cement composition,
- wherein said cement composition is a magnesium-based composition comprising from 10 to 50 wt % of a magnesium silicate, from 8 to 35 wt % of an alkaline silicate, from 5 to 20 wt % of an alkaline base and from 10 to 55 wt % of water.
