Non-Jacketed Self-Regulating Cable

How is the non-jacketed cable applied to a pipe?

 

Self regulating cable can be applied in a linear or spiral fashion along the pipe. Self-regulating cable can be overlapped or crossed, though avoid excessive concentration of cable in a confined space (i.e. spooling of cable in single spot). To apply the correct amount of heat to protect the pipe from frost, follow the below multipliers.

Multiply the pipe length by the units below to decide how much cable is required. Example: on a 20ft pipe length in Chicago (-30F possible ambient) with no insulation, use 20 x 1.5 = 30ft of cable. Apply the cable in an even spiraling fashion along the pipe. For plastic/PVC pipes, double the QTYs obtained using the formula above.

For best results, use Warmup’s Aluminum Tape (SR-TAPE-AL) to secure the cable to the pipe.

 

Insulation None 1/2″ 1″
1″ pipe 0F Min. Ambient 1 1 1
-30F Min. Ambient 1.5 1.25 1
2″ pipe 0F Min. Ambient 1.5 1.25 1
-30F Min. Ambient 2 1.75 1.5
