Industrial control wiring

Start by defining the environment, voltage, current, and required flexibility, then pick a cable family that fits. For indoor control panels, PVC control cables from trusted series like OLFLEX CLASSIC are common choices. If electromagnetic interference is a concern, opt for shielded options such as UNITRONIC LiYCY with a copper braid. Always match the conductor cross‑section and core count to the electrical load and the temperature rating to the ambient conditions.

Shielding reduces EMI and protects delicate signals in noisy environments, so choose shielded cables for runs near motors, drives, or high‑frequency equipment. Look for a copper braid shield and plan full coverage when possible, with the shield terminated to ground at one end to minimize ground loops. In practice, UNITRONIC LiYCY shielded cables from Lapp provide a copper braid shield suitable for multi-core control runs. Remember that shielding adds cost and stiffness, so reserve it for situations where interference would compromise reliability.

Yes. Beginners should start with straightforward, standard PVC control cables with clear color coding and simple installation, such as basic 0.75–1.0 mm² cores for small control circuits. Professionals tailor the choice to the application, opting for shielded multi-core cables with appropriate cross-sections and temperature ratings for longer runs or noisy environments. Consider the environment, the number of signals, and future expansion when selecting brands like OLFLEX CLASSIC, UNITRONIC LiYCY, or other reputable PVC control cables.

Plan for proper mounting and strain relief, and use appropriate connectors and cable glands to avoid damage. Observe bending radii and avoid tight kinks, especially for multi-core shielded cables. Check that insulation, temperature rating, and voltage class match the equipment and follow relevant standards such as IEC 60204-1. Regular inspections for insulation wear and shield integrity will extend life and reliability.

Common choices include Lapp’s OLFLEX CLASSIC for robust general purpose PVC cables, and UNITRONIC LiYCY for shielded multi-core control runs. These series differ in flexibility, temperature tolerance, and whether they include shielding; for example, shielded LiYCY cables handle EMI better, while classic PVC cables offer easy handling and cost efficiency. Choose based on your environment, required core count, and tolerance for bending and exposure, keeping industrial wiring best practices in mind.

Verify that the cable’s cross-section, insulation, and shielding are compatible with your terminal blocks, relays, and connectors. Match the number of cores and color coding to your control scheme, and ensure the bending radius and length suit the installation. Use approved cable types from reliable brands and follow installation guidelines to prevent signal loss or overheating in industrial wiring systems.
