Introduction

Glass-fiber wrapped enameled flat copper wire is first enameled on high-quality copper conductors, and then wrapped with glass fiber. According to customer needs, the required temperature resistance index of the insulating paint is matched, and the baking treatment is performed to make the glass fiber, insulating paint and conductor bonded into a whole.

The fibre covering shall consist of a combination of polyester and glass fibres. the glass fibres shall be electrical-grade continuous-filament glass yarn. the polyster fibre shall be a high-grade yarn resulting from the linear polymerization of ethylene glycol and terephthalic acid. the maximum content by weight of polyester fibre in the yarn shall not exceed 50%.

Feature

The coating shall be characterized by the following different grades of thickness:

PG1, bare conductor with 1 layer of polyester glass fibre or 2 layers of finer polyester glass fibres that together, comply with the dimension.

PG2, bare conductor with 2 layers of polyester glass fibre.

grade 1 PG1, enamelled grade 1 (grade 1) with 1 layer of polyester glass fibre (PG1).

grade 1 PG2, enamelled grade 1 (grade 1) with 2 layers of polyester glass fibre (PG2).

grade 2 PG1, enamelled grade2 (grade 2)with a layer of polyester glass fibre (PG1).

grade 2 PG2, enamelled grade 2 (grade 2)with 2 layers of polyester glass fibre (PG2).

Tolerance On Conductor Dimensions
The tolerance on conductor dimensions for Polyester Glass-Fibre Wound Varnish Enamelled Rectangular Copper Wire can vary depending on the specific manufacturing standards and requirements.
