Features of Warmup SR Self Regulating Commercial Grade Heating Cable

Warmup’s SR Self-Regulating Cable is a cut-to-length cable designed for residential and commercial roof and gutter de-icing and pipe freeze protection applications. The cable is constructed of a self-regulating polymer core that varies its output as the ambient temperature conditions change. The cable output increases along the length of the cable when the ambient temperature decreases and the cable output decreases as the ambient temperature increases, saving energy and eliminating hot spots. The cable can be overlapped without overheating and is reinforced with a durable jacket that is UV resistant.

• Voltage: 208 - 277 VAC
• Wattage: 5W/ft at 50°F, 8W at 32°F
• Length: 250ft Reel
• Cable Type: Self-Regulating
• Max Continuous Exposure Temp: 150°F
• Roof and Gutter Deicing Applications: Suitable For All Roof Types
• Buss Wires: Twin 16 AWG Copper Buss Wires
• Matrix: A semi-conductive polymer core whose electrical resistance varies with temperature. When process temperature drops, the core’s heat output increases; conversely, as process temperature rises, heat output decreases
• Jacket: The flame retardant insulation jacket is a thermoplastic rubber material with excellent water resistance. It resists certain mildly corrosive chemicals
• Tinned Copper Braid: The braid covering the jacket provides an effective ground path and mechanical protection.
• Overjacket: The TPR overcoat protects the braid, and provides resistance to water and certain inorganic chemical solutions, and is UV resistant
