The Basics Behind ESD Applications

Special ESD (electrostatic discharge) cable carriers are used in numerous industrial sectors. When designing a cable carrier system into an ESD application, there are two important reasons why these specialized carriers should be used: (1) to prevent ESD from seriously damaging sensitive electronic components during the manufacturing process; and (2) to curb safety concerns in applications that involve using, processing or storing hazardous (flammable) materials.

In order to protect sensitive electronic components against ESD, the cable carrier must maintain long-term conductivity. Also, most electrical apparatuses, which are used to operate a plant’s pumps, lights, instrumentation, and other equipment, can often be a potential source of ignition. To prevent explosions, cables carriers that are constantly dissipating any electrical charges in a controlled manner are ideal for housing and protecting these cables.

Cable Carrier Materials and Design

Materials

The material of the cable carrier is critical to ensure it is suitable for ESD environments. Here at igus®, we developed a special material called 'igumid ESD', which immediately dissipates electrostatic charges in controlled manner.

igumid ESD has been tested to millions of cycles in a wide number of different applications. These cable carriers possess higher rigidity and have approximately 15 percent lower density, which makes them ideal for longer, unsupported travel lengths. The ESD energy chains are also durable, maintenance-free and can withstand harsh environmental conditions.
