The present invention relates to a fire-resistant cable comprising at least one electrically insulating composite layer based on at least one cementitious material and at least one starch, and the process for manufacturing same.
Claims16
Power and/or telecommunications cable comprising:
- at least one elongated conductive element;
- and
- at least one electrically insulating composite layer surrounding said elongated conductive element,
- wherein the electrically insulating composite layer comprises at least one starch, at least one plasticizer for starch and at least one cementitious material, and
- wherein the cementitious material represents from 10 to 50% by weight relative to the total weight of said electrically insulating composite layer.

Power and/or telecommunications cable comprising
- at least one elongated conductive element;
- and
- at least one electrically insulating composite layer surrounding said elongated conductive element, and
- wherein the electrically insulating composite layer comprises at least one starch, at least one plasticizer for starch and at least one cementitious material, and
- wherein the starch and the plasticizer for starch represent from 50 to 90% by weight relative to the total weight of said electrically insulating composite layer.
2 more elements
Power and/or telecommunications cable comprising
