Technical Specification:

Data

Polyester 200 is a multi-purpose dual coated wire which combines the excellent physical and electrical properties of a polyesterimide or modified polyester base coat with the added chemical resistance, surface toughness, smoothness and high thermal rating of a polyamide-imide linear polymer topcoat. The combination of these two high quality resins produces a coating which has outstanding surface toughness, abrasion resistance, flexibility, chemical resistance, burnout and thermal shock resistance and dielectric strength. These properties coupled with careful selection and processing of the copper produce an enamelled wire which meets the current exacting requirements of the electrical industry.

 

Chemical Properties

Polyester 200 has outstanding chemical resistance, being unaffected by all common solvents, including those used for cleaning hermetic units e.g. perchloroethylene, mild acids and alkalis. Its negligible extraction by refrigerants make it first choice for use in hermetically sealed refrigeration units.

 

 

Temperature Classification

Polyester 200 is suitable for use in Class 'H' Systems provided that a compatible and correctly applied impregnating varnish is used and that all other associated insulating materials are of the same classification.

However, as is well established, this classification is dependent on other factors, especially the nature of the operating environment. When evaluated in accordance with the procedures laid down in I.E.C. Publication 172 this covering has a Temperature Index of the order of 212°C.

    all good.
    The shipment I received in about six days to Spain. The product complies with the description. Good quality.

  2. Amazing quality

    I used this wire for an electromagnet/coilgun project.
    So far, it hasn't let me down. It's strong, flexible and the enamel is amazingly effective, even at high currents.
    Sure it makes it annoying to strip the enamel (normally needs fine sandpapering) but, at the end of the day, a good enamel means less chance of ruining your project with current surges :)

    Awesome product, and each reel should last you ages depending on the application.

    5 stars from me! *****
