SPM special machine slip-ring & cable-reel


                      SLIP RING  SREX506 SERIES EXPLOSION PROOF


The slip ring assemblies are designed for an operational voltage of max. 680 V. Depending on the size and the application of the spring-driven cable reel both sliprings for the data transmission (mA-range / data bus systems) and sliprings for power transmission (up to max. 638 A) can be used. The individually admissible amperages of the slipring assemblies can be gathered from the selection list. The material of the cover the slip ring is steel Correspond to protection class IP 66

 POWER SLIP RING SREX506 Ex "db"


 Explosion proof (EXPLOSION PROOF) Basic principle In this method of protection it is allowed that the explosive atmosphere comes into contact with the sliding contacts in tension. However, these must be enclosed inside a case designed to withstand the pressure developed (Pmax = 10 bar) due to a possible explosion inside the same and to prevent the spread of the flame outside the case and trigger the explosive atmosphere outside it. The philosophy of the method is based on the consideration that it is not possible to prevent a gas from spreading everywhere. Therefore it would be unthinkable to build electrical equipment contained in a watertight enclosure to the point of preventing the entry of gas. A slip ring case has been built so that the gas enters inside, but in the event of contact between it and the ignition source (arc or spark) the resulting explosion is contained inside and the burned gases escape through special joints, (flat and rotating joints) created between the various parts of the enclosure, designed in such a way that the flame, exiting it cools and only the combustion product arrives outside, by now cooled and unable to ignite the surrounding atmosphere. Main features The main feature of the POWER SLIP RING is the robustness of the construction which guarantees reliability over time. Reference standards: - EN 60079-1: 2014
