The NG DRY A.C. MOTOR RUN CAPACITORS are manufactured with a dielectric material that consists of two sheets of polypropylene film. Each one with a thin layer of vacuum deposited metal on one side. Metals are selected according to final application aluminum/zinc and zinc. Both films are acting as electrodes in the capacitor; because this metal is just a few hundred amstrongs thick, it has a very limited current carrying capability at any single point in the dielectric. To compensate this limitation, the entire edge of each electrode is bonded by a metallized endspray that has a relatitively high current carrying capability. The endspray serves as the termination point for the internal connections of the capacitor, this construction minimizes the current at any single point of the electrode. This current capability is enhanced by soldered or welded end terminations.
These capacitors are self-healing, a property of the metallized film to restore itself to an operating condition when a dielectric breakdown occurs during operation.
The thin metal layer around the fault point will act like a low current carrying fuse. Under a fault condition the current will evaporate the metal around the fault point and clear the fault. This is accomplisshed by special frame work of the film with a specific ohmic resistivity and low melting point temperature the evaporation of the electrode will result in a capacitance loss that is virtually unmeasurable. All films for capacitors have particularly low dielectric losses, high level of insulation and dielectric strength.

NG dry A.C. motor run capacitors are designed to be used in various types of applications like electric motors and HID ballasts. They are used as part of the current limiting circuit for power factor correction. The A.C. capacitors provide direction by shifting the current in the windings so that the motor simulates the operation of a two-phase motor. These motor run capacitors are designed specifically to be used with permanent split-phase capacitor motors in swimming pool, whirlpool and spa applications where strict form and fit restrictions are required.
NG dry motor run capacitors are designed to meet performance testing outlined in EIA-456 standard. Test programs are run continuously at NG and at third party laboratories to monitor production and to design improvements. These tests confirm reliable performance of NG capacitors used within rated conditions. Ongoing tests include: accelerated life, over voltage, mechanical, terminal to terminal voltage, and voltage to case voltage tests.
