Sun Touch has kept versatility in mind making Warm Wire in both 120vac and 240vac for multiple effects based on floor and room insulation. Warm Wire heating elements and power cables are armored to reduce jobsite abuse, and reinforced with DuPont Kelvar to protect against jobsite stretching and avoid causing hot spots. The heating elements are braided with 304 stainless steel braids and the power leads are braided with tin-coated copper. They are also grounded from end to end with full current carrying capacity to give maximum protection in case the wire is damaged.
