6W/11mm TLC-PW (HTLe-PW) increases or decreases the heat output in a self-regulating way depending on the change of the ambient temperature, the cable reduces its temperature as it warms, so this minimizes the effect of the heat on the temperature sensitive roof materials and it will never overheat or burnout even when wrapped over itself (overlapped). With optional outer- jacket, the heating cable is resistant to watery and inorganic chemicals and protects against abrasion and impact damage. Elec-Trace Aqua provides termination, power connection, splice, tee and end seal kit will reduce installation time and require no special skills or tools
