Resistors made of a heavy resistive alloy tape - up to 15 mm high, 2 mm thick- extremely tenacious at high and low temperatures, practically unbreakable against shocks and trepidations; it is wound helicoidally on
edge through slots of one or several refractory segments, held fast by a through screw bolt. The refractory insulator support is of high quality, being able to withstand severe vibrations and thermal shocks. Steel terminals are clamped onto the resistive tape under strong pressure.

Outstanding Features

High dissipating Power within a reduced space
Simple and rugged construction
Easy adjusting intermediate "live" tapping
Ability to withstand heavy overload surges
Standard Tolerance: ± 10%
T Type: on this Series, two or three helix tapes in parallel are employed so as to obtain lowest possible ohmic values.

Applications: Starting, stopping, controlling electrical motors on locomotives, cranes, steel mills...
