Maybe more effective bundling ? >that's what the material suggests. I read the answer to my question of not flowing thru less resistance toward the center of a copper wire with a thicker AL cladding as the outer areas of conductivity are geometrically larger supplying more free electrons in this Cu AL apparently topping more conductive copper below. >now tell me why that wire is more resistive ? as per common knowledge. AlSi coatings are used for environmental protection. They will not improve surface conductivity directly, but can preserve conductivity of the coated material and assist to reduce corrosion. I've never seen it offered for copper. Perhaps you can offer a reference or link to the material you're refering to? Aluminum is more resistive by volume than copper (less resistive by weight).....so is unlikely to be used to reduce skin resistance of a copper conductor directly, in the short term. RL |
