Reliable Clip-On Cable Identification for Industrial Wiring
Clear and consistent cable identification is essential for maintaining organised electrical installations and simplifying maintenance operations. The Partex PTC20/21W provides an effective solution by allowing identification labels to be fitted directly onto cables through a transparent protective pocket. Its clip-on design makes it particularly useful when marking existing wiring, where conventional closed marker sleeves cannot easily be installed without disconnecting conductors.
The Partex PTC series is designed for industrial electricians, automation engineers and electrical panel manufacturers who require flexible, dependable marking solutions. Compatible printed identification inserts can be positioned inside the transparent sleeve, helping improve circuit identification, reduce troubleshooting time and maintain professional wiring standards throughout machinery and electrical control systems.
Typical Applications
- Industrial electrical control panels and switchgear assemblies.
- PLC cabinets and industrial automation wiring.
- Electrical distribution boards and terminal connections.
- Machine building and OEM equipment manufacturing.
- Retrofitting identification markers onto existing electrical wiring.
- Manufacturing machinery and production line control systems.
- Electrical maintenance, circuit tracing and fault diagnosis.
- Professional cable and conductor identification in industrial installations.
