Insights

insulated wireHaving many years of experience as a producer of high precision square wires and flat wires for the manufacturing of connectors and electronics, we have extended our product range with wrapped insulated flat wires and wrapped insulated square wires. We can insulate copper almost as well as every commercially available copper alloy and aluminum alloy by wrapping it with paper or foil according to your specifications in high-precision quality with your needs and requirements. RST offers you an unparalleled range of dimensions.


Basic material

insulated wireAlmost all conductive basic materials are possible. RST manufactures bare conductors from many types of wires.

Insulation and structure:

insulated wireWe offer you a broad range of insulating materials. Whether paper, Nomex®, Kapton® or foil: we manufacture according to your specifications. On request, the external layer is also glued. You can choose the insulation structure: edge to edge or overlapping. The degree of overlapping depends on dimension and insulation. On request, the wire is coiled in synchronous or opposed form.


Specialities

insulated wireFor our basic conductors of square wires, We guarantee the closest dimensional tolerances of up to 5µm combined with excellent straightness. The corner radius and the diagonal will be defined according to your specifications. On request laid "layer to layer" is available. For our bare conductors of flat wire we also guarantee the closest dimensional tolerances of up to 5µm in width and thickness as well as a camber of under 10 mm/m.

Your advantage: compared to common round wires, our ínsulated flat wires and square wires can be coiled "layer to layer", i.e. seamlessly.
