PME

PME Evolution is the latest family of sliprings, characterized by a high degree of protection IP65 and suitable for harsh environmental conditions.
With versions combined microsignal rings or power rings of 20 A, 50 A to 80 A, these outlets can be combined with rotary air passages or fluidic sliprings. And all enclosed in an aluminum and insulation, modular and innovative design.

ΓΕΝΙΚΟΣ ΚΑΤΑΛΟΓΟΣ

PRP

The slipring PRP Type is protected; housing in insulating material with high mechanical resistance and also not changeable to temperature variations. The internal pipe, diam. 48 mm., free of cables, allows passage of piping for fluids, driving shafts and metallic ropes. Brush-holders can have blade or copper graphite brushes.

PRS

The slipring PRS Type is mostly useful for outside applications, due to a steel housing with protection degree IP 55. Brush-holders have blade brushes. Copper graphite brushes on request.

PMP

The slipring PMP Type is a product studied by Ravioli’s Company to solve customer requests and to obtain high performance in small dimensions. This slipring, thanks to a 5 mm. lenght among rings, allows to use a very high number of strips in a small dimension. Brush-holders have copper graphite brushes.

ATEX

EXD sliprings are ATEX approved for Zone 21 and 22, and they are IP65; compact and modular, they are particularly required in dusted areas subject to a high explosion risk.

PRG

The PRG Type, without housing, is available with a large diameter possibility: 85 mm. up to 2000 mm., and for this it is possible to have a wide internal passage and different Amperes. Brush-holders can have blade or copper graphite brushes.

The PZG Type, without housing, has the advantage to have a wide internal passage and to be axially very compact thanks to insulating rings which devides the conductor rings. Brush-holders can have blade or copper graphite brushes.

PZG

PSG

The sliprings: PSG Type without housing, PSP protected and PSP waterproof, have been requested for years for their execution and for the slideway between rings and brushes with a peculiar V contact. Brush-holders have copper graphite brushes.

PSP

The sliprings: PSG Type without housing and PSP protected, have been requested for years for their execution and for the slideway between rings and brushes with a peculiar V contact. Brush-holders have copper graphite brushes.
