Summary: | The method includes a step in which a conductor wire (
4
) is coated with a fused plastic material (
7
) and a step in which said plastic material is cooled, and it is characterized in that it includes a step in which a lubricating material (
9
) is sprayed onto the surface of the cable (
2
).
Said cable (
2
) which includes at least one conductor core (
4
) and at least one coating of plastic material (
7
) incorporates a lubricating material (
9
) on the exterior coating.
The equipment (
1
) for the manufacturing of electrical cables (
2
) which includes a reel (
3
) for supplying a conductor wire (
4
) to an extruding head (
5
), which has a tank (
6
) containing plastic material (
7
) for coating the aforesaid conducting wire (
2
), and a reel (
11
) for taking up the cable (
2
), includes a device (
8
) for the application of a lubricating material (
9
) onto the surface of the cable (
2
). |
