摘要：A method of manufacturing a sheathed electrical heater assembly comprisingthe steps of: molding a core element into a desired shape, the core element having anouter surface; heating the core element at an elevated temperature sufficient to release
organic material from the core element; placing a heating element in communication withthe core element; and, encapsulating the core, and the heating element in an insulationprotection layer, whereby the heater assembly is formed. Additionally shown is asheathed electrical heater assembly comprising: a core made of an organo-ceramicmaterial; a heating element in communication with the core; an insulation protection layerencapsulating the core and heating element to produce the heater assembly, the
protection layer comprising and organo-ceramic material; and, a sheath encapsulating theheater assembly, the sheath also comprising an organo-ceramic material.
