SSAPP type heating cables are resistive wire, twin conductor (two cores) heating cables, robust and round in cross section with a core made of electro-resistant alloy or copper (depending on cable length). The cables have a three-layer insulation and a conductive sheath made of aluminum foil, with a protective conductor made of tinned copper. This construction gives them excellent durability.
Their main advantage is the temperature-resistant outer sheath that allows them to be installed in asphalt (the cables can withstand temperatures up to 200 °C for up to 180 minutes).
They are designed for per unit length loads of up to 40 W/m, but if the cable has a good thermal connection to the surrounding medium (for example if the cable is installed in concrete) the per unit length load can be increased up to 50 W/m.
