As the names imply, constant wattage cable uses fixed wattage output per linear foot and does not automatically adjust in response to temperature changes. Self-regulating cable is manufactured with a resistance matrix placed between its 2 buss wires that varies the ohms resistance per linear foot to automatically adjust in response to temperature changes. Learn more about this in our blog Self-Regulating vs. Constant Wattage Heating Cables.

By attaching a heating cable to the exterior of a pipe, it will transfer the heat to the pipe to prevent frozen pipes. And with the use of pipe insulation the heat will be evenly spread and won't dissipate as quickly.

Unfortunately there's no set answer for this because it depends on many factors such as the diameter of the pipes, the installation density of the heating cables, the outdoor temperature, the installation of thermal insulation sleeves, etc.
