    Construction of High Power Braking Aluminum Case Resistors

    1.An aluminum encased consists of an alloy metal coil-type resistance element assembled into an aluminum enclosure.
    2.Following high-temperature anodization, the enclosure is filled with a specialnon-flammable cement paste and after hardening. Insulation is applied through a high temperature process.
    3.Since this component is embedded in the heat-proof cement, it is not affected by external mechanical force, and dusty environments.
