Definitions
- the invention relates to a coating composition for metallic conductors, such as wires, with improved resistance to partial discharge and good mechanical properties.
- Three-phase motors e.g. motors controlled by frequency converters, or high-voltage asynchronous machines require the use of wire windings that meet the high requirements for thermal durability and mechanical properties, especially the bending strength of the insulating layer, in order to be able to survive high-voltage loads or pulsed voltage loads without damage.
- wire windings of electrical equipment Another requirement for wire windings of electrical equipment is the partial discharge resistance of the wire coatings.
- wire windings lying next to one another can be subjected to high-voltage loads or pulse-shaped
- the coatings must have a high resistance to partial discharge.
- a coating composition which consists of a binder and a particulate material, the particulate material being present in the binder in an amount of 1 to 65% by weight and metal oxides, for example Titanium dioxide, zirconium oxide, zinc oxide, iron oxide or alumina can be.
