Commonly Used TXLPHeating CableThere are two types: one with a single core wire, both ends of which are connected to "cold wires," forming a loop at both ends when in use, known as a single-core heating cable; the other with two core wires, one connected to the heating wire at the cold wire end and the other forming a cold wire loop, known as a twin-core heating cable. Since the cable has its own heating function, some also call it a "heating cable."
