A nichrome or other alloy resistance wire is then spirally wound around the cord and the copper banding tape. The number of turns per inch will determine the watts per foot of heating cable. A second tape of either adhesive-backed copper of TFE tape is then wrapped over the heating element wire and the "monel" staple completely covering the first copper tape. This assembly is repeated alternately along the conductor. The second tape covering is simply to hold down the resistance wire and make contact with the "monel" staple and first copper tape.

Rating	125 deg C, 300 Vac, Horizontal flame.

Conductor	16 AWG - 10 AWG solid or stranded round, tinned or bare copper.

Insulation	Extruded TPE, 60 mils minimum average thickness, 54 mils minimum thickness at any point before separation, 27 mils minimum thickness at any point after separation. See facing page for compound.

Assembly	Two conductors, same as type SPE-3. Over the insulated conductors, an adhesive-backed copper tape 0.125 inch by 0.0025 inches thick is applied as a band at periodic intervals with the adhesive side down against the PVC insulation. Dependent of the AWG size of the SPT-3 conductor, a staple made of "monel" metal or stainless steel is driven through the insulation of one of the copper conductors and over the adhesive-backed copper tape at a slight angle to the conductor.

Jacket	Extruded TPE, 40 mils minimum average thickness, 32 mils minimum at any point, applied overall. See facing page for compound.

Shield	Optional.

Covering	Optional, Extruded TPE, 13 mils minimum thickness at any point, see Facing Page for Compound.

Standard	Appliance Wiring Material UL 758.

Marking	General.

Use	Pipe heating cable where the acceptability of the combination is to be determined by Underwriters Laboratories Inc.
