BAM High-Voltage Capacitors

TYPE BAM CAPACITORS offer superior electrical characteristics coupled with small size. They are conservatively designed for long life under harsh conditions. Winding and case design can be customized to the conditions of use, including ambient operating environment (oil, air, SF6, etc.), electrical environment (pulsed discharge, AC, ripple voltage and current, etc.)

TYPE BAM CAPACITORS are normally housed in phenolic tubing with epoxy end seals and a threaded stud at each end for connections. Special housings are available in epoxy fiberglass, PVC, polycarbonate, and polysil (for outdoor applications). Threaded inserts and axial leads are also available.

SIZE: The case sizes listed are not necessarily the smallest possible for a given capacitor. If size and shape are critical to your application, Chicago Condenser Corporation will be pleased to work with you to optimize a capacitor to your needs. Wide range of case sizes in several styles available. A revised design which employs stock material may result in little additional cost. If a custom case is required, cost may depend heavily on quantity.

CONTAINER: BAM capacitors are housed in phenolic tubing, with a threaded stud terminal at each end. Epoxy fiberglass, PVC, Polysil, or Polycarbonate tubular containers are available upon request. For large BAM’s, use of an alternative enclosure can sometimes result in substantial savings. BAM capacitors tend to be much more cost effective than metal-cased units for voltages > 50 KV. This results from the high cost of terminals and custom cases for large, metal-enclosed, high voltage capacitors. As BAM capacitors are fabricated in an insulating tubular container with terminals at each end, the case becomes the insulation between the terminals. As a result of the epoxy seal at each end, BAM capacitors tend to be somewhat more fragile than metal-enclosed capacitors.

IMPREGNANT: BAM capacitors are normally impregnated with a high grade organic-based dielectric fluid; however, silicone-based dielectric fluid can often be used upon request. The use of organic-based dielectric fluids in BAM designs results in substantial cost reductions relative to silicone-based fluids, at the expense of operating temperature range.

WINDING DESIGN: Capacitors can be constructed in a range of winding designs (e.g., extended foil, tab constructions, etc.) and can be fabricated from a wide range of dielectric materials including polypropylene, polyester (“Mylar”), polycarbonate, etc. with varying layers and configurations of paper. Each combination of construction and materials has its advantages and disadvantages. For example, an extended foil design gives the greatest current carrying capability and lowest ESR at the expense of a somewhat higher inductance that can be achieved with a tab design. The inductance and ESR in tab designs depends on the number of tabs. Increasing the number of tabs in a winding increases the time required in manufacture, and therefore, the cost to the customer. Mylar is a good general purpose dielectric with a relatively high dielectric constant which results in a smaller capacitor that polypropylene; however, polypropylene has much better high frequency characteristics. The proper use of fluid-impregnated paper layers is important in capacitors which see frequent and wide swings in voltage (AC, pulse discharge, etc.), as it can provide a “self-healing” medium with greater tolerance to electron injection in highly stressed regions of the capacitor.
