HEATING ELEMENT FOR A SHEET ELECTRICAL INSULATOR

摘要

The proposed electrical heating element (1) is mounted on a solid sheet electrical insulator (2) to be heated. The electrical heating element (1) consists of graphite in flexible form, in particular a graphite film, fabric or web. This heating element is relatively insensitive to mechanical stress and is highly efficient. In one embodiment, the insulator is a metal-coated glass plate, which can be used to make an external heatable vehicle mirror.
