Abstract
An assembly and a method for manufacturing an insulation layer of an electrical conductor are presented. The electrical conductor is enclosed in a cavity of a mold. Spacers embedded into holes of the mold are movable into the cavity for holding the electrical conductor in the cavity to maintain a gap between the electrical conductor and surface of the cavity. Distance of the gap is defined by thickness of the insulation layer. Spacers are movable into the holes of the mold from the cavity to maintain even surface of the cavity. Insulation compound fills entire gap and is cured to form the insulation layer having homogenous thickness.
Claims20
An assembly for manufacturing an insulation layer of an electrical conductor comprising:
- a mold comprising a cavity for enclosing the electrical conductor;
- a supply tank for holding an insulation compound;
- a supply line connected to the supply tank and an inlet opening of the cavity for filling the insulation compound into the cavity;
- and
- a spacer embedded into a hole of the mold, wherein the hole is connected to the cavity,
- wherein the spacer is configured to be movable from the hole of the mold into the cavity for holding the electrical conductor in the cavity to maintain a gap between the electrical conductor and a surface of the cavity,
- wherein the spacer is configured to be movable into the hole of the mold from the cavity to maintain an even surface of the cavity, and
- wherein the insulation compound fills entire gap between the electrical conductor and the surface of the cavity forming the insulation layer.
A method for manufacturing an insulation layer of an electrical conductor comprising:
- enclosing the electrical conductor into a cavity of a mold, wherein a spacer is embedded into a hole of the mold, and wherein the hole is connected to the cavity;
- moving the spacer from the hole of the mold into the cavity for holding the electrical conductor in the cavity to maintain a gap between the electrical conductor and surface of the cavity;
- filling an insulation compound into the gap from an inlet opening of the cavity through a supply line, wherein the supply line is connected to a supply tank;
- moving the spacer into the hole of the mold from the cavity to maintain an even surface of the cavity;
- and
- continuously filling the insulation compound into the gap until the insulation compound fills entire gap between the electrical conductor and the surface of the cavity forming the insulation layer.
