The resistive element is wound onto resistance value and tolerance which will withstand all the substrate and welded to the caps. The wound rod is accepted industrial cleaning fluids. Values are marked then moulded and edfitt into aluminium housing to give in accordance with IEC 62. optimum stability and reliability.
