ELECTRICAL HEATING DEVICE

摘要

An electric heating device includes a flexible resistor ribbon of alloy with high specific impedance, disposed in fiberglass or plastics net, forming insert, which is incorporated in different plastic shells. It is given the relationships for choice of area, length and width of the heating ribbon for incorporation in plastics, which provide high reliability and life span. It is described different structures of plastic heaters in forms of sheets and strips. It is shown different applications.
