UCM COIL CONSTRUCTION

Conductors used are high conductivity 100% virgin copper, HD 3000 heavy enamel coated conductor is normally used or single or double glass over HD 3000 heavy enamel. Some applications may require mica turn taped conductors.

Coils are shuttle wound pressed to assure conductor alignment, dipped in varnish, oven cured.

Leads are cleaned and coils are spread and checked in a form for proper shape and uniformity.

Coil leads are insulated with sleeving or mica tape depending on the voltage and application.

Ground insulation consists of VPI mica tape and/or a combination of mica tape and wrapper. An armor tape, Dacron, or glass is applied.

For 6600 volts and up, a semi-conducting tape is applied to the slot section of the coil.
