PERISAI4D RTP SLOT This behavior can be observed especially in the needle winding technology. This behavior repeats itself with every layer which leads to a spiral shaped crossover section at the side of the winding. Coil winding can be structured into several groups regarding the type and geometry of the wound coil. Since an orthocyclically wound coil with at least 300° of the circumference of winding layers has the tightest circle package of the wire cross-sections. The best volume use is found when the winding is parallel to the coil flange for most of its circumference.|{Avoid|Keep away from} {The top|The highest} 10 Slot Win 138 {Mistakes|Errors}
