Twin 12 AWG Copper Buss Wires – Provide reliable, consistent electrical current
FEP Insulation Jacket – Electrically insulates buss wires
Pairing Jacket – Secures two buss wires together and provides wrapping surface for Nichrome wire
Nickel Chromium Wire – Cable heating component
FEP Insulation – Rugged outer sheath protects heating cable, assures longer service life, and provides protection against environmental application hazards
Tinned Copper Braid – Plated copper braid increases robust construction, provides ground path and provides additional protection in any location (suffix “C” in model number)
FEP – Fluoropolymer overjacket, over the braid, provides protection from most aqueous and chemically corrosive solutions (suffix “T” in model number) – ideal for trace heating systems installed in hazardous areas with explosive atmospheres
