ELEKTROFOL MAGNET COIL

Listing ID #4009215

Coils made of Anodised Aluminium Strip dissipate heat much faster since every single turn is itself part of the heat emitting exterior surface. In a conventional fibreglass or nomex covered and varnished wire coil, the dissipation of heat from the Coil centre is significantly obstructed. The poor thermal conductivity of the inter-turn insulation as well as air inclusions results in heat build-up that may ultimately destroy the Coil. Particularly in Oil Cooled Electromagnet Coils wound with Anodised Aluminium Strip, every single coil turn is directly exposed to oil cooling. On the other hand, in Wire Wound Coils, inside turns do not come into contact with the Oil. Hence the cooling is uneven, resulting in hot spots within the inner layers of the coil.
