SF is a fixture wire insulated with silicone rubber, available as a solid or stranded conductor, valued for heat resistance in lighting and high-temperature applications.
SF designates a fixture wire insulated with silicone rubber, available with either a solid or stranded conductor. Fixture wire is used to connect lighting fixtures to their supply, often in locations where heat is a concern, and silicone rubber insulation provides excellent heat resistance. This makes SF well suited to the elevated temperatures found in and around lighting fixtures.
Silicone rubber retains its flexibility and insulating properties at high temperatures that would degrade many other insulations, allowing SF wire to perform reliably near hot lamps and in high-temperature equipment. The choice of solid or stranded conductor suits the wire to different flexibility needs.
In commercial and industrial settings, heat-resistant fixture wire like SF carries power to lighting and equipment in warm environments. Recognizing the designation is part of identifying wire suited to high-temperature applications.
Because silicone rubber retains its flexibility and insulating properties at high temperatures that would degrade many other insulations, SF fixture wire performs reliably near hot lamps and in high-temperature equipment, with the choice of solid or stranded conductor suiting it to different flexibility needs.
Recognizing the designation is part of identifying wire suited to high-temperature lighting and equipment applications where silicone insulation provides the needed heat resistance.
At Windy City Wire, the focus on quality low-voltage and fixture wire includes heat-resistant types like SF. Supplying wire with insulation suited to high temperatures helps ensure dependable performance in the lighting and equipment connections of commercial and industrial systems.
