Abstract
An electrical heater has a number of heater elements, each having a metal tube with an exterior end and an interior end. An electrical resistance coil is located within the tube with a conductor pin connected to the coil and protruding from the tube. Electrical insulation powder surrounds the coil within the tube. A cavity within the end of the tube receives an insulating member having a passage through which the conductor pin extends. A layer of epoxy is located between the insulating member and the powder. The tubes are arranged into three electrical phase groups. Interior conductor pins of the groups are electrically connected to each other in a Y-configuration. A phase divider of electrical insulating material has three sections dividing the electrical phase groups of the conductor pins.
