Paint for Partial Discharge Resistant Enameled Wire and Partial Discharge Resistant Enameled Wire

TECHNICAL FIELD The present invention relates to a paint for partial discharge resistant enameled wire and a partial discharge resistant enameled wire.

1. A made by at least one selected from a metal oxide fine particle sol and silicon oxide fine particle sol to the enamel wire coating material is dispersed, the metal oxide fine particle sol or silicic
Elemental oxide fine particle sol is not compatible with enamel wire paint.
Metal oxide with an average particle size of 100 nm or less in an excellent dispersion medium
Transparent or milky white containing fine particles of substances or fine particles of silicon oxide
A colloidal state, at least one fine particle sol selected from that of the metal oxide particles and silicon oxide particles, 3 with respect to the resin component 100 parts by weight of the coating enameled wire
A partial discharge resistant enameled wire coating composition, characterized in that the coating composition contains 100 to 100 parts by weight.

2. Gold directly on the conductor or through another insulating layer.
Select from metal oxide fine particle sol and silicon oxide fine particle sol
The metal oxide fine particle sol or the silicon oxide fine particle sol has an average particle diameter of 100 n in a dispersion medium excellent in compatibility with a coating material for an enameled wire.
a transparent or opalescent colloidal state containing metal oxide particles or silicon oxide particles of m hereinafter, the metal oxides
At least selected from fine particles and silicon oxide fine particles
One kind of fine particle sol is 100% resin content of the coating for enameled wire.
Enamel wire containing 3 to 100 parts by weight with respect to parts by weight
Resistance partial discharge resistant enameled wire you characterized by comprising the use paint was applied baking.

3. A partial discharge resistant enameled wire according to claim 1.
Paint, directly or via another insulating layer on the conductor, the coating baked
A partial discharge resistant enameled wire, characterized in that a lubricous coating layer is provided on the outer periphery of the coating layer formed by applying .
