Heater for electrical radiator has casing supporting element in casing with electrical insulation layer having high thermal conductivity

摘要

The heater for an electrical radiator (11) has a tubular resistance element (13) forming a heat conductor with an electrical insulation and a self supporting casing. The casing extends over the full length of the heating conductor. The casing can be enclosed in a layer of electrical insulation. The electrical insulation can have a high thermal conductivity.
