Warming up to Electrical Heating Cables

摘要

Heating cables are commonly referred to as heat trace cables, heat tracing, or heat tape, while the most advanced cable design, self-regulating heating cables, are also known as self-limiting cables. Whatever they are called, all work largely on the same principle: when voltage is applied across a length of wire of a given resistance, it then dissipates a fixed level of power in the form of radiating heat based on ohms law. Heat is emitted due to the resistance in the cable alloys as the current moves through it, thereby warming up the immediate physical surroundings.
