3 ReliabilityThe outstanding reliability ofSpecimas slipring columns is due tomany innovative technicalsolutions backed by years ofexperience in this specialised Resistance to corrosionThe extensive use of stainless steelfor all mechanical parts, from theframe down to the fixings,guarantees an excellent mechanicalresistance even in particularyhostile climates and environments,without FlexibilityA unique characteristic of theslipring columns is the possibilityto meet almost any requirementsby using a wide range of componentsespecially developed andmanufactured by CompactnessThe special design of the Specimasrings enable the construction ofvery compact sections, stillensuring a high degree of electricalinsulation and a perfect Wiring facilitiesAll side panels on the Specimasslipring column can easily beremoved thus providing good accessfor wiring to rings and signal rings are, as standard,prewired to a numbered BrushStand still slipring applications oftenrequire a high degree of derating of theamperage carrying capacity ofconventional carbon the physical size of thebrushes is not always a solution, sincethe actual contact area does notincrease proportionally.
