The resistive element is a low ppm resistance wire that is wound on a special grade porcelain tube. The terminals have fully welded construction to provide a good mechanical and electrical contact. The assembly is embedded in the aluminum casing. The aluminum casing is made from high quality heat sink grade material, which helps to dissipate the heat from the resistor at the faster rate resulting low change of resistance with respect to temperature, as resistance varies in direct proportion to temperature. The casing is filled with high purity and special silica sand to extract the heat from the resistor body at the slower rate. The conduction of heat thorough the sand brings uniform heat to the aluminum casing for further dissipation. This protects the panels from being heated internally. Terminal contacts are provided with the screw arrangement for easy wiring.
