<p>PURPOSE:To prevent the snow adhesion even when the current flowing in an over-head cable is a small current, in a thawing cable where a heating wite is wound around on the over-bead cable. CONSTITUTION:A thawing cable is constituted by winding a water-repellent heating metallic tape 2, which is made by forming a water-repellent layer 4 on the surface of a magnetic metallic tape 3 for heating and thawing snow, according current of an over-head cable, on the over-head cable, an when the current of the over-head cable is a small current, not enough the magnetic metallic tape 3 to heat and thaw snow, it reduces the adhesive strength of adhering snow by the water-repellent layer so as to drop the snow.</p> |
