Class 200 Glass Fiber Covered Silicone Treated Film-Insulated Rectangular Copper Magnet Wire

Types

Glass Fiber Covered Silicone Treated Bare Film-Insulated Rectangular Copper Magnet Wire Thermal Class 200

Glass Fiber Covered Silicone Treated Heavy Rectangular Copper Magnet Wire Thermal Class 200

If an underlying film coating is used, it shall have at least a class 180 rating. The glass fiber covering shall be wrapped firmly, closely, evenly, and continuously around the wire.

The glass fiber covering shall be treated with a modified silicone insulating varnish or silicone compound to provide a tough outer finish. If a tracer is used, one or more ends of glass yarn shall be black or green, and the dye or pigment used for this purpose shall be sufficiently stable so as to retain its color identity after the silicone treatment and subsequent baking.

Properties

Adherence and flexibility	Single or Double with underlying film: no cracks visible in the film insulation after 20% elongation. Examine with normal vision and without removing the glass fiber covering.Double without underlying film: not less than 75 V/mil (2950 V/mm) of minimum thickness of the glass fiber covering on one side.  NOTE—The minimum thickness of the glass fiber covering is 35% of the maxi- mum increase in dimensions calculated from: Rectangular—Single Covering of Polyester Glass Fiber: 0.0060-0.0095 inches—Double Covering of Polyester Glass Fiber: 0.0100-0.0160 inches
Elongation	Not less than 32% for a thickness of 0.049 in. (1.25 mm) and greater, or 30% for a thickness less than 0.049 in. (1.25 mm)
Springback	Glass fiber covered bare: not greater than 5ºGlass fiber covered Heavy film-insulated: not greater than 5.5º
Dielectric breakdown	Not less than 90 V/mil (3543 V/mm) of the minimum thickness of the glass fiber covering on one side plus the minimum breakdown given in the film-insulated wire(Heavy 500-1500；Quad 900-2500), if applicable.  NOTE—The minimum thickness of the glass fiber covering is 35% of the maxi-mum increase in dimensions calculated from:—Single Covering of Polyester Glass Fiber: 0.0060-0.0095 inches—Double Covering of Polyester Glass Fiber: 0.0100-0.0160 inches
