			Revised:2012-05-18


Rating	250 deg C, 600 Vac, Horizontal flame.

Conductor	18 AWG - 10 AWG solid or stranded round, nickel-plated copper strands.

Insulation	Extruded MFA or PFA, 20 mils minimum average thickness, 18 mils minimum thickness at any point.

Heating Element	Heating Element - Nichrome, copper alloy or other suitable resistance wire is spirally wound around the insulation; the AWG size of wire, number of turns, length between contact with the copper conductor are dependent upon the wattage demand and the voltage used to energize the cable.

Assembly	Over two insulated conductors laid parallel, a MFA or PFA, 5 mils minimum thickness at any point, is extruded to form a two conductor parallel cord. This cord is now prepared for the spiral wound heating element. This is done by carefully removing the insulation along the length of the cord so as to bare the copper conductor for approx 1/2 in widths at periodic intervals. A spirally wound nichrome or the type of resistance wire is then carefully wound the length of the core and may be soldered to the exposed conductor. By varying the distance between contacts with the conductors, the number of turns per inch of resistance wire and the AWG size (resistance) of the spirally wound wire, different wattages per foot per service voltage can be obtained. Arrange order - insulated conductor with heating element, optional inner covering, jacket, optional middle covering, optional shield and optional outer shield.

Shield	Optional.

Covering	Inner and middle covering - Optional, Fiberglass braid. Outer covering - Optional, Extruded PFA, FEP or MFA, 13 mils min at any point.

Jacket	Extruded FEP, MFA or PFA, 20 mils minimum average thickness, 16 mils minimum thickness at any point.

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.
