HEAT EMITTING WIRE MATERIAL AND SNOW MELTING ELECTRIC WIRE USING THE SAME

摘要

PURPOSE:To provide possibility of melting snow with good effectiveness by spirally forming a ridge consisting of conductive metal at the periphery of a core consisting of ferromagnetic substance. CONSTITUTION:A heat emitting wire 1 consists of a consolidatedly formed Al covering 4 having a spiral ridge 3 at the periphery of a core 2 consisting of ferromagnetic substance. When current flows in this heat emitting wire 1, most of it flows in the ridge with good conductivity to produce a strong mag. field in the core 2, and heat is generated by a large iron loss.
