Various rubber parts, extensions, or grommets are one of the most important parts of electrical devices. Speaking of rubber wire grommets, we must point out their role – primarily because of the thermal and electrical insulation they provide. Rubber wire grommets are used when we want to protect electrical cables or wires from various damage, contact with water, abrasion, thermal changes – or other possible defects that might occur.
For rubber wire grommets we sometimes use different names such as cable guards or rubber cable protectors. However, it is all the same rubber round-shaped part – that has a hole in its central part where cables or wires should be inserted. This way, electrical installation can be protected from external influences. What exactly do we mean here? For example, it is clear that the contact of electricity with water could be very dangerous. On the other hand, various scratches or damage that can occur on the cable or wires due to friction or contact with sharp edges – can also be very inconvenient. Of course, there are also thermal conditions, when cables or wires can overheat – due to the operation of an appliance or machine. Therefore, rubber wire grommets play an important role in the purpose of thermal insulation and protection.
Fortunately, today rubber is a fairly cheap raw material from which such or similar parts are produced – which can be bought at very reasonable prices. We use them very often in everyday life, without perhaps paying enough attention to them. All those who work in offices, for example, know that cables from computers, printers, or monitors – are often connected with rubber grommets so as not to clutter your work surface or parts around the desk. These extensions are mostly made of rubber – although we can also see them in the form of silicone attachments. They are very flexible and can be made in different diameters to suit the purpose for which they are intended.
