Wire markers

Cable markers are a permanent and reliable means of cable identification. In addition to the formal aspect, they facilitate all maintenance and service work. Cable marking in most installations is required by safety regulations. However, even without this compulsion, it is a very simple and best way to organize and speed up the wiring work of various components. Cable Marking is especially important where dozens and hundreds of conductors are handled in switchboards and control cabinets for automatic lines, telephone exchanges, server rooms, supervisory equipment and other electrical systems.

Wire markers - complex wiring systems

From small switchboards and electrical cabinets to large industrial projects, wire marking allows for identification at a later date. This is accomplished by designing and documenting how workers and staff will wire individual devices and control points. This is necessary for later correct operation and quick location of properly marked cable by cable markers. Cable markers usually contain cable name, type or type of connected device, the same for both ends of the cable pathway. Both numbers and letters of the alphabet are used for this purpose. There are also ready-made elements with voltage parameters, e.g. 12V, 24V, 220V or 380V, or markers of AC and DC current type.

Due to the importance of the information contained on the elements identifying the cabling, it must be resistant to accidental damage and have indelible printing, inscription or embossing with the target information. This is ensured by appropriately hard and at the same time flexible materials used for fasteners, slides, clips or tapes and plates which carry important information. These, like other mounting accessories, are usually made of heat resistant, smokeless materials, which allows them to be used in all locations, regardless of the safety requirements of fire regulations.

Identification of cables with large diameters

In case of single conductors or whole bundles and groups of cables of bigger diameters it is possible to apply the identification of conductors by means of strip information strips fastened on the bundle with additional clips. The information on the information carrier is applied manually with an abrasion resistant pen or by sticking pre-printed tapes. This solution allows for multiple use of a single strip according to the marking in case of modernization or repair of the installation.

Cable marking - clip-on and clip-off systems

Cable marking is possible regardless of whether there is access to the conductor end or the cable is already connected to a connector or device. Depending on the type of location, we can use slide-on elements on the exposed end or use a range of other self-locking solutions. All of these elements are available for most types of cables from a few to several millimeters in diameter.

  • Marking of cables using slip-on elements with a closed profile. These can be oval, flattened or triangular in cross-section. They can be marked with a printer, manually with a marker or they have ready made markings. They can be sold in sets or individually with symbols to create your own markings. Marking can be done with individual pre-made symbols or with slip-on ribbons for longer markings.

  • Self clipping cable markers allow this to be done on running and connected cables or where the previous method is not possible. Various clips and strips made of flexible materials are stable and do not move longitudinally or axially on the cable. This creates a clear structure that is easy to read during inspection or maintenance work on electrical cabinets and switchboards.

In specific places and requiring good insulation, heat shrinkable wire markers (phase markers) or other types of wiring are used. They have a marking corresponding to the type of wire in the target location e.g. N, L1, L2, L3. After the heating process they seal the cable end and at the same time keep the graphic information about the wiring type.
