Abstract
The invention provides a cable for power distribution and/or data transmission, the cable comprising a core comprising one or more metallic conductors and a sheath surrounding the core, the sheath being formed from a polymer having a tensile modulus of at least 1.5 GPa, wherein the outside diameter of the sheath is no more than 13.5 mm and the stiffness of the cable is at least 0.01 Nm2. Advantageously, embodiments of the cable can be readily blown and pushed through a microduct without deforming.
Claims13
A cable for power distribution and/or data transmission, the cable comprising:
- a core comprising one or more metallic conductors;
- and
- a sheath surrounding the core, the sheath being formed from a polymer having a tensile modulus of at least 1.5 GPa;
- wherein the outside diameter of the sheath is no more than 13.5 mm;
- and
- the stiffness of the cable is at least 0.01 Nm2.
A cable system comprising:
- one or more bundles or microducts, each bundle comprising a plurality of microducts;
- at least one optical fibre installed in one of the plurality of microducts;
- and
- at least one metallic conductor cable installed in another of the plurality of microducts, wherein the at least one metallic conductor cable includes a core comprising one or more metallic conductors, a sheath surrounding the core, wherein the sheath is formed from a polymer having a tensile modulus of at least 1.5 GPa, wherein an outside diameter of the sheath is no more than 13.5 mm, and wherein the stiffness of the cable is at least 0.01 Nm2.
A method of installing cables, comprising:
- installing one or more microduct bundles, each bundle comprising a plurality of microducts;
- blowing at least one optical fibre into one of the plurality of microducts;
- and
- blowing at least one metallic conductor cable into another of the plurality of microducts, wherein the at least one metallic conductor cable includes a core comprising one or more metallic conductors, a sheath surrounding the core, wherein the sheath is formed from a polymer having a tensile modulus of at least 1.5 GPa, wherein an outside diameter of the sheath is no more than 13.5 mm, and wherein the stiffness of the cable is at least 0.01 Nm2.
