All of Backer-Springfield’s heater wires (see Heater Wire product) are available on spools in bulk, but we also have the capability to make heater wire harnesses. In order to meet your exact specifications, you simply specify your necessary wattage, length, and terminations.
Backer’s heater wire harnesses are available in 3 different constructions (per European standard).
Single-Ended Wire Harness
Single-ended harnesses have the leads exiting on the same side of the harness. The final insulation layer can be silicone or PVC.
Double-Ended Wire Harness
Double-ended harnesses have one lead on each end of the assembly. These can be made with PVC or silicone insulation and can be finished with glass or aluminum braid for abrasion resistance.
Double Insulation Wire Harness
Double insulation harnesses are designed to meet Class II standards per IEC 60335-1. This European standard requires 2 layers of insulation each of which is at least 1mm in thickness. PVC or silicone insulation can be used in either layer of this construction.
Some of the applications for heater wire harnesses are:

Backer-Springfield’s thermoplastic (PVC) insulated heater wire is an excellent choice for use in low-wattage applications. This premium quality thermoplastic jacket material has passed the most critical odor tests of the domestic refrigerator manufacturers. In addition to being used in bulk form for harness, PVC insulated wire is widely used in the manufacture of foil bonded and sewn to foil heaters.
