The heating element is multi-strand resistance wire, braided with AMOX™ (AWH model) or fiberglass (AIH model) yarn and knitted into the serpentine shape to minimize thermal shock and tensile stress from expansion and contraction. The side-by-side wire configuration permits the lead wires to be on one end.
Heavy AMOX™ or Fiberglass Overbraid Cover
The Wide Heavy Insulated Tapes have flexible, AMOX™ or fiberglass braided sleeving over the heating element to provide additional dielectric strength for application on conductive surfaces (use directly on metal). Fiberglass tapes (AIH models) provide capability up to 900°F (482°C) and AMOX™ tapes (AWH models) to 1400°F (760°C).
Molded Plug Option (120V)
Standard Wide Heavy Tapes do not include a power plug. 120V tapes (less than 10 amps) may be ordered with the optional molded plug (-MP). No power plug option is available for 240V tapes. Commercially available connectors may be installed for the customer or sourced locally. Duo-Tapes®
do not utilize a grounding circuit and provide a two wire connection.
For Earth Ground Leakage protection a circuit protector (30ma GFCI) is recommended.
High current heating tapes (greater than 10 amps) require two sets of power leads.
