Electrical heating element and heater incorporating same.

摘要

An electrical heating element for a radiant electric heater comprises an elongate electrically conductive strip (1) for partial embedding edgewise in a base (3) of thermal and electrical insulation material. The strip (1) is composed of an elongate continuous portion and an elongate discontinuous portion integral with the continuous portion. The discontinuous portion is intended for embedding in the base (3) and is provided with a plurality of discontinuities (4, 4A, 4B, 4C) therein such that in operation of the heater current flow in the discontinuous portion is reduced or eliminated.
