Vacuum applications in the transformer production industry Air drying The Hot Air drying process is mainly used for drying of high voltage transformers windings or for drying od the active part of smaller distribution transformer. Process consists of hot air circulation followed by pumping down of the heating chamber to a pressure below < 1hPa. The design criteria of the pumping speed depends on the weight of the insulation material.
The Cost of RV Boondocking - Boondocker's Bible· Most RVs are equipped with an AC-to-DC converter that sends only a trickle charge of power (2 to 10 amps) to the battery, with AC power coming from either shore cord or generator. A few RVs come with "smart converters" that can send as much as 60-90 amps on bulk charging, and then drop down to 10 amps or even 2 amps, to top off.
