Embodiment Construction

[0008] It is worth noting that the terms "first", "second", etc. as used herein do not denote any order, number or importance, but are used to distinguish one element from another. The term "a" does not denote a limitation of quantity, but rather that there is at least one of said item. The modifier "about" used in relation to a quantity is inclusive of the stated value and has a meaning determined by the context (eg, includes the degree of error associated with measurement of the particular quantity). It should be noted that all ranges disclosed in the specification are inclusive and independently combinable.

[0009] The present invention discloses an insulating layer which can be used to protect and isolate electrical components of electrical devices such as motors, generators and the like. The invention also discloses a method of applying the insulating layer on an electrical component for an electrical device. Suitable examples of such electrical components include cond...

Abstract

Disclosed herein is an article comprising an electrical component and an electrically insulating layer disposed upon the electrical component, wherein the electrically insulating layer comprises a thermosetting polymer and a nanosized filler, wherein the nanosized filler comprises metal oxide and diamond nanoparticles that have an average largest dimension of less than or equal to about 200 nanometers.

Description

technical field [0001] The present invention relates to composite coatings for groundwall insulation in electromagnetic devices such as engines, generators, methods for their preparation and articles obtained therefrom. Background technique [0002] Electrical component perimeter wall insulation for electrical installations is usually made of multiple layers of material. The multilayer structure contributes to a higher resistance to corona discharge. It is also desirable for the insulating layer to have a high breakdown voltage value so that it can withstand the high voltage environment of electrical devices such as motors and generators. Multilayer structures usually consist of a fiber backing made of glass and additional layers made of mica. The use of multi-layer structures is time-consuming and expensive. Additionally, the use of multilayer structures often results in thicker insulation layers and larger components. [0003] Therefore, it is often desirable to use in...
