Reduce installation space by up to 25% -motor cables

A motor cable is a comparatively simple cable. Its only task is to supply the motor with electricity. As it is connected to a frequency converter, its voltage class is 600V/1,000V, and it has four cores (L1, L2, L3, PE). Motor cables are used where large amounts of energy are transferred; however, automation technology requirements have increased dramatically in recent years.
To meet all these requirements and stand up to the continuous mechanical load in an energy chain, materials and manufacturing processes are essential for motor cable function. Ensuring reliable drive power supply under heavy loads remains an elementary task. A harbour crane is a good example.
igus motor cables are made with special high-quality networked XLPE insulation materials. They are specifically designed for energy chains and provide low capacitance for fast, low-loss switching times and a very high insulation temperature reserve with higher current density. They must also have a long service life when used in large-scale travels or tight bends. The quality of the stranded wires in the cores must also be very high in order to move the cable continuously in small installation spaces. This ensures a long service life and reliable power supply.

Reduce installation space by up to 32% – servo cables

Like a motor cable, a servo cable supplies the motor with power. Of course, we use the advantages of XLPE core insulation here, too. However, a servo cable also has other crucial functions: it supplies the motor brake with energy and/or carries the signal from the temperature sensor to the frequency converter. For this purpose, a servo cable has one or two additional control pairs with extra shielding so that no interference reaches the frequency converter. Servo cables often also have an overall shield to prevent electromagnetic interference because they then have better electromagnetic compatibility specifications. A servo cable is therefore much more complex than a motor cable and also has many more cores. The additionally shielded control pairs mean that the cable is no longer as symmetrical as a motor cable, for example. This poses a particular challenge for the design of a high-quality cable. The solution is the gusset-filling extruded inner jacket, which provides a firm foundation for the shielding and wraps around the additionally shielded control pair, guiding the cores lengthwise. The inner jacket is especially important here, since it is the only way to achieve long core service life and guarantee durability for the high-quality shielding. Long travel distances and small bend radii put even more strain on the cable, so that special protection must be provided. 

Reduce installation space by up to 32% – measuring system cables

Measuring system cables are often referred to as feedback or encoder cables. They are used for signal feedback from the transmitter system to the frequency converter. Information such as speed and angular position is transmitted at high density through various signal core combinations in the cable. This means a colourful mix of various cross section, core number and shielding combinations that require special protection during movement. This is achieved with special pair shields or element jackets.
Long travels and small bend radii pose a special challenge, since that is where extreme forces act on the cable. The sensitive components in the cable make it important to use especially high-quality, selected materials in measuring system cable manufacture. High-quality materials such as TPE, a continuously gusset-filling extruded, robust inner jacket, a particularly closely woven shield with high coverage and an optimal braid angle are essential components of a durable, fail-safe measuring system cable.
