AI Technical Summary

Technical Problem

Certain materials in the insulating and semiconductive layers of electric cables are too soft and elastic, making it difficult to achieve a clean and smooth cut during cable preparation, which can affect the cable's properties.

Method used

An installation with a cylindrical cooling box that uses a refrigerant material to cool the cable section, hardening the semiconductive and insulation layers, allowing for precise and smooth cutting.

Benefits of technology

The cooling process enables the cable layers to be hardened below their glass transition temperature, facilitating a smooth and controlled cutting operation, thereby maintaining the cable's properties.

Abstract

The invention relates to an installation (101) for preparing a cable (1) comprising a conductor surrounded by an insulation system (2) including at least one insulating layer (3) and at least one external semiconductor layer (5). According to the invention, the installation has a cooling device (101) for a section of said cable (1) in the form of a cylindrical cooling box (102) containing dry ice, the electrical cable (1) passing through the box (102) in order to be cooled below the glass transition temperature of the external semiconductor layer (5) and subsequently allow machining of the external semiconductor layer (5).
