Abstract
A cable, in particular a power and/or telecommunication cable, has at least one elongated electrically conductive element, and at least one fire-resistant layer surrounding said elongated electrically conductive element. The fire-resistant layer is a ceramic layer in direct physical contact with the elongated electrically conductive element.
Claims18
A cable comprising:
- at least one elongated electrically conductive element;
- and
- at least one fire-resistant layer surrounding said elongated electrically conductive element,
- wherein said fire-resistant layer is a ceramic layer in direct physical contact with said elongated electrically conductive element, and said ceramic layer is obtained by heat treatment of a liquid ceramic composition, and
- wherein the solid ceramifiable composition comprises at least one silicon oxide and at least one aluminium oxide.
