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.

SCREW TERMINATION OPTIONS

EITHER END

SAME END ALONG LENGTH

SAME END ALONG WIDTH

Simple to wire stainless steel screw terminals are available arranged at each end, on the same side arranged along the length, or on the same side arranged along the width. All screw terminations are good up to 20A. Optional ceramic covers are available.

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.

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.
