This style of wiring is the most prevalent for nozzle band heaters, as it contributes to the most flexible and space saving installation.
Mica insulated lead wires rated for 842°F (450°C) with tightly wrapped stainless steel overbraid are used, providing protection in abrasive environments. The stainless steel braid exits parallel to the heater centerline through a low profile stainless steel cap. This cap also acts as a strain relief, guarding against excessive flexing or pulling of the lead wire.
By keeping the lead wires away from the heater, less damage from high temperature contact is likely to occur.
The standard leads are 10" of stainless steel wire braid over 12" of flexible leads.
