摘要

The electric heating cable has a heating unit (10) that is formed with carbon fiber bundle comprising several carbon fiber yarns. An insulating sheath (20) is provided surrounding the heating unit. The carbon fiber bundle is formed by wrapping or twisting carbon fiber yarns with glass fiber, fiber-stone, or ceramic fiber formed of aromatic polyamide. The carbon fiber yarn with porous structure is formed from metal particles.
