Method of making a mineral-insulated, compacted, bendable cable
11043316 · 2021-06-22 · ·

A mineral-insulated cable has a non-circular cross-sectional shape that does not allow the internal wires to twist or change alignment during manufacturing of the cable.

CREATING A CONDUIT FROM A COPPER CABLE
20200358267 · 2020-11-12 ·

A conduit is formed in a cable (10) having a plurality of wire bundles (12) by removing one or more of the centrally located bundles (12). A bundle (12) is removed by penetrating a wedge (14) into the bundle (12) and then pulling the pierced bundle (12) out of the cable (10). The bundle (12) is then engaged by wheels (18) of a device (17) and pulled out of the cable (10) thereby forming the conduit. The process is repeated dependent on the size of the cable (16) and the desired size of the conduit.
