Conductor:
Flexible stranded 27% nickel plated, annealed copper.

Sizes:
#20 AWG - 4/0 AWG

Insulation:
Phlogopite mica tapes, fiberglass braid jacket, high-temperature saturant. A phlogopite mica tape thermal barrier and a fluoropolymer tape moisture barrier are both applied over the core. An overall fiberglass braid is then treated with a high temperature saturant.

Armor braid optional.

UL approved lead wire 450° C.

Passes IEEE 383 modified 210,000 BTU vertical tray flame test at 1800° F, with circuit integrity for 2 1/2 hours minimum.

Non UL operating temperature can withstand up to 2400° F short term.

Used in critical areas where standard high temperature lead wire is not sufficient to maintain circuit integrity due to extreme temperatures, or exposure to open flame. Used for equipment wiring in iron mills, steel mills, glass plants, and cement kilns.
