<p>The invention relates to a sealed cable penetration comprising an outer layer of a heat resistant material which expands upon heating and an inner layer of a flexible, compressible, heat resistant material and that the cable is intended to be inserted in the inner layer. The invention further relates to a method for pulling new cables through the sealed cable penetration, where the inner layer of flexible, heat resistant material is removed, while the outer layer of heat expanding material is maintained, whereafter one or more new cables are pulled and the annulus between the new cables and the outer layer is filled with the flexible, heat resistant material.</p> |
