The article Pliograph+ 2.8 U white from Ses-Sterling is a labelling ring booklet for the clear identification of cables, lines and other installation components in the field of electrical and IT technology. It is a series of labelling rings made of PVC, compiled in a booklet to enable uniform labelling. The rings are in the colour white and feature a black print with the marking “U”. The width of the rings is 2.8 mm, making them suitable for a wide range of cable diameters, particularly for medium to large cables in industrial and commercial applications. The booklet contains 150 identical rings, each marked with the same identifier, ensuring consistent and quickly recognisable labelling.

Applications
These labelling rings are primarily designed for installation technology, especially in the field of electrical and data cabling. They serve for the visual identification of cables, lines, connections or device terminals to avoid errors during assembly, maintenance or repair. The marking “U” may have different meanings depending on internal systems or standardisation, for example, as a designation for a specific line function, voltage level or installation group. Typical use is in cable trays, enclosures or distribution boxes, where clear and durable labelling is required.

Functions and Equipment in Detail
The rings are made of PVC, a robust and flexible plastic that can be easily wrapped around cables and provides stable durability. The colour white ensures high contrast against the black print, improving readability even in low light conditions. The print “U” is clear and distinctly visible, enabling quick identification. The width of 2.8 mm is suitable for a wide range of cable diameters, particularly for cables with diameters of approximately 4 mm to 12 mm, depending on the material’s elasticity. The booklet is designed so that the rings can be removed individually without damaging the entire booklet.

Technology Explained Simply
The technology of labelling rings is based on a simple but effective principle: a flexible, ring-shaped label is wrapped around the cable and held securely by the elastic properties of the PVC material. The labelling is done during manufacturing, so no additional marking or print template is required. The use of PVC ensures a certain resistance to mechanical stress, moisture and minor temperature influences, which is sufficient for use in indoor and protected outdoor environments. The white colour with black labelling is a common combination in industry, as it offers high readability and contrasts well against dark cables.

Compatibility and Accessories
The rings are part of the Pliograph+ labelling system from Ses-Sterling and can be combined with other products from the same series to create a uniform labelling system. Using them together with other labelling rings from the same product line enables structured and clear labelling of complex installations.

Installation and Mounting
Mounting is done by simply placing the ring around the cable. Due to the elastic properties of the PVC material, the ring can be installed without tools. It is recommended to place the ring at a location where it is clearly visible and not subject to bending or tensile stress. The rings are designed for permanent marking, but their suitability should be checked in cases of high mechanical stress or aggressive environments (e.g. high temperatures, chemicals). Use typically occurs without additional adhesives or fixings.

Advantages in Operation
The use of these labelling rings provides clear and durable identification of cables, significantly simplifying maintenance, repair and expansion of installations. The uniform labelling with “U” enables quick assignment within a system. The robust PVC structure ensures long service life, and the easy handling reduces installation effort. The packaging with 150 rings in a booklet offers practical and organised storage and distribution, especially for larger projects or series installations. The combination of white colour, black labelling and 2.8 mm width represents a proven solution for visual labelling in electrical and IT installations.
