HT Mica Strip Heater

TUTCO HT Mica Strip heaters are a cost-effective and reliable way to provide uniform heat over a flat surface. Best suited for low to moderate temperatures, our Mica Strip heaters offer a wide variety shapes, sizes and termination styles.

HT Mica Strips feature thin construction and high-quality insulation for effective heat transfer and excellent dielectric qualities.

Our standard lead-time on this product is 10-15 business days. Some expedites available. Consult factory.

Lead Options

Either End	One End From Thickness	One End On Top

Leads can be arranged at either end or at the same end, exiting from the top, the thickness at the end(s) of the heater or the width at the side of the heater. All HT Mica heaters come standard with mica insulated leads. Standard lead length is 10″. Other lengths available upon request.

Engineering Note
Improperly chosen lead arrangements are a major cause of application problems. Use special care in selection of leads where physical abuse and high temperatures are likely.

Either End	Same End Along Length	Same End Along Width

Lead Protection

	Plain Leads Our high temperature mica insulated leadwire with nickel standard conductors is suitable for continuous service up to 842°F (450°C).
	Sleeving Fiberglass silicone rubber coated sleeving class C1, 392°F (200°C) service. Provides extra insulation where wire is exposed to heat, molten plastics or abrasion. Rated for 1500 volts at 428°F (220°C), except 5/16" size which has no voltage rating.
	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. Maximum length: 12"
	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" 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" or wider.
