HT Mica Strip Heater

Plain Leads
Jacketed for continuous service up to 482°F (250°C) with nickel standard conductors. It is recommended to use Monel® lugs. High temperature mica tape lead wire is suitable up to 842° F (450° C) max. with nickel stranded conductors. Outer jacket is glass Teflon® finish. The use of Monel® lugs is recommended. Better Band comes standard with mica tape.

Sleeving
Fiberglass silicone rubber coated sleeving class c -1, 392° F (200° C ) service. Provides extra insulation where wire is exposed to heat, molten plastics or abrasion. Rated 1500 volts at 428° F (220° C), except 5/16″ (7.9 mm) size which has no voltage rating. This size used primarily to enclose multiple insulation wires in heat and abrasion resistant covering.

Stainless Steel Braid
Stainless steel over braid is most commonly specified in applications where leads may be subjected to abrasion due to movement of the application. Lead wires may be rubbing together or passing over sharp objects.

Stainless Steel Armor
Used over leads in areas where more protection is necessary. Selected for similar applications as the stainless steel braid, in addition to applications where non-fluid contamination may come in contact with the leads. This lead protection is not as flexible as the braid. Stainless steel square lock construction.

Convoluted Armor
This is a seamless product and can be attached to the heater so that fluids do not contaminate the leads. This system of lead protection is generally associated with the “Sealed Band” construction. Not recommended where leads are flexed in the application.

Relief Spring
This optional relief spring is welded to the band sheath. It adds protection from abrasion while keeping the leads very flexible.

Specify length, maximum length: 12″ (30 cm)

Copper Elbow
Simple straight abrasion-resistant stainless steel armor or moisture-resistant armor is attached to a 90° copper elbow to accommodate applications where lead access is only possible from one side and armor exit direction is a concern. When ordering without a swivel option, specify direction of 90° copper elbow.

Pipe Coupling/Extension Tube
These pipe couplings, welded to the heater sheath, provide a method of fastening conduit or armor to the heater which can be disconnected from the heater as required. Standard stainless steel.

Standard Terminal Box
Designed for protection safety, snap-off cover leaves terminals easily accessible. For heaters 1 1/2″ (38.1 mm) or wider with screw terminals at one end along length on top. Also with screw terminals at one end across width, on top 2 5/8″ (67.0 mm) or wider. Terminal cover protects terminals against accidental grounding or short circuit due to spillage.
