GAUGE 220

The GAUGE brand of enameled copper wire is produced on an OEM (Original Equipment Manufacturer) basis by readily established Copper Wire Manufacturers using foreign based Technologies.

In Its finished form, the GAUGE 220 is a multi-purpose dual coated wire which combines the excellent physical and electrical properties of a Polyester-Imide based coat with the added smoothness and high thermal rating of a Polyamide- Imide linear polymer top coat. The combination of these two high quality resins produce a coating which has outstanding surface thoughness, abrasion resistance, flexibility, chemical resistance, burnout and thermal resistance and dielectric strength. This specification of wire is readily recognzed by the UL (Underwriter Laboratory) Standard, as well as other International Standard.

PRODUCT CHARACTERISTICS

The GAUGE 220 wire is coated with a dual film of insulation, the underlying film is composed primarily of a synthethic resin based on Polyester-Imide which is heat resistant and the superimposed film is composed primarily of Polyamide-Imide which is abrasion resistant.

The insulating film of the wire is made by baking insulating varnish on the conductor uniformly. The film is harmless to the conductor and also have sufficient durability.
