Transductor combines the electrical performance of aluminum with the strength and durability of standard steel rail into a heavy-duty, high current capacity conductor rail. The highly conductive and corrosion resistant extruded aluminum conductor rails are fastened to the steel rail with steel compression bolts at close intervals to ensure excellent electrical conductivity between the aluminum and steel. Ideal for harsh and high-temperature environments and applications requiring very high currents, Transductor is available in rail sizes from 25lb to 115lb rail with capacities from 1800 amps to 12000 amps.
