UL 3257

UL 3257 wire is used for internal wiring in applications where it is not exposed to flexing or immersion in liquids. UL 3257 may be used in oil burner ignition systems, range top burners, ovens, piezoelectric spark igniters, furnaces, heaters, oil burners, infrared fixtures, stoves, dryers, test equipment, cooking equipment, and similar equipment. The UL 3257 wire's construction makes it resistant to UV, ozone, radiation, heat, moisture and chemical exposure.
