11801652-70 CoilsGMW standard Electromagnet Coils are designed for high reliability and high fields at modest power consumption. They are wound from precision slit, high conductivity copper with mylar interturn insulation and a fibreglass outer wrap. They feature separate aluminum heat sinks with integrated copper cooling tubes. The complete coil assembly in then vacuum impregnated with epoxy resin to produce a void free structure that will not degrade under continuous or cycled operation at maximum power dissipation. Protective overtemperature switch interlocks are mounted on all heat sinks.
