Starting current: 0.5m:2A; 1m:4A; 2m:6A; 5m:12A Heating Cable Structure: 1. Copper conductor 2. Conductive heating element 3. PE outer sheath Technical Datas: 1. Working voltage: 10~15V DC 2. Rated power: 25W/m (at 10C degrees) 3. Max maintain temperature: 50C degrees 6. Length of power cable: 0.4m 7. Width * Thickness: 8mm * 3mm 8. Min bend radius: 15mm Pre-assembled, Easy to install and use. Energy efficient. 40cm cold conductor.Heat shrink tubing for joining applications.The temperature-resistant resistance wire is surrounded by a high-quality protective insulation. The cable is a Self-regulating / Self-limiting heating cable, Ideal for freeze protection and low temperature process maintenance such as your RV's fresh water supply tubing in need of heat protection, the smaller volume of fluids within these lines are normally the first to freeze up.
