SFF is the same as SF fixture wire but in a flexible grade, using finer stranding for greater flexibility while retaining silicone rubber heat-resistant insulation.
SFF designates a fixture wire that is the same as SF but built in a flexible grade, using finer, more numerous strands in the conductor for increased flexibility. Like SF, it is insulated with silicone rubber for excellent heat resistance, suiting it to lighting fixtures and high-temperature applications. The flexible stranding makes SFF easier to bend and route where flexibility is important.
By combining heat-resistant silicone insulation with flexible stranding, SFF serves connections that must both withstand heat and flex easily, such as leads on fixtures that move or are routed through tight spaces. The finer stranding provides the added pliability.
In commercial and industrial settings, flexible heat-resistant fixture wire like SFF carries power to lighting and equipment where both flexibility and high-temperature performance are needed. Recognizing the designation is part of identifying wire suited to these demands.
Because the finer stranding adds pliability while the silicone insulation provides heat resistance, SFF serves connections that must both withstand heat and flex easily, such as the leads on fixtures that move or are routed through tight, high-temperature spaces.
Recognizing the designation is part of identifying flexible wire suited to high-temperature lighting and equipment connections that must both withstand heat and flex easily.
