Abstract
A single line for a charging cable includes an open support structure (011, 012) having a longitudinal extent, at least one channel conductor (2) made of electrically conductive material, and an insulation (3). The at least one channel conductor (2) wraps around and contacts the open support structure (011, 012) along its longitudinal extension. The insulation (3) wraps the open support structure (011, 012) and the at least one channel conductor (2). At least one channel (4) for a cooling fluid (5) is provided and is formed by the support structure (011, 012) and the channel conductor (2). The insulation (3) is impermeable to the cooling fluid (5) and is electrically insulating.
Claims20
A single line for a charging cable, comprising:
- a) an open support structure in the form of a helix and having a longitudinal extent,
- b) at least one channel conductor made of an electrically conductive material, and
- c) an insulation,
- wherein:
- d) the at least one channel conductor is the form of a helix that wraps around and contacts the open support structure along its longitudinal extent,
- e) the insulation encases the open support structure and the at least one channel conductor,
- f) at least one channel for a cooling fluid is formed by the support structure and the at least one channel conductor,
- g) the insulation is impermeable to the cooling fluid and is electrically insulating, and
- wherein:
- h) the support structure has a first thread direction, the at least one channel conductor has a second thread direction, and the second thread direction differs from the first thread direction, or
- i) the pitch ratio, which is the smallest pitch of the helix of the at least one channel conductor divided by the pitch of the helix of the open support structure, is greater than 4/3 and less than 50.
A single line for a charging cable, comprising:
- an open support structure having a longitudinal extent,
- at least one channel conductor made of an electrically conductive material, the at least one channel conductor being wrapped around and contacting the open support structure along its longitudinal extent,
- an insulation encasing the open support structure and the at least one channel conductor, the insulation being reinforced by fibres, and
- at least one channel for a cooling fluid defined by the support structure and the channel conductors,
- wherein:
- the insulation is impermeable to the cooling fluid and is electrically insulating, and
- the fibres in the insulation are arranged substantially in a layer and in said layer cover between 30 and 90% of the area of the layer.
