When it comes to installing cables, doing it right is crucial for their reliable performance. Let’s take a deep dive into the best practices for cable installation for a variety of different cables and wires. Taking the time to follow these best practices while installing electrical cables will ensure that nothing goes wrong and functions as per design. By following these best practices, you can ensure the safe and efficient operation of your electrical system for years to come.
Proper Cable Routing
The way cables are routed should minimize their exposure to environmental hazards such as moisture, heat, and vibration, as well as protect them from physical damage and interference from other electrical systems. When it comes to railway signalling cables, they should be routed along the tracks, taking into account potential hazards from passing trains or maintenance vehicles.
It’s also crucial to consider the type of cable when determining its routing. For example, power cables and aluminium cables should be routed separately from other types of cables to prevent interference and ensure maximum power transfer. Similarly, PVC cables should not be exposed to direct sunlight, as this can cause degradation and reduce their lifespan.
Properly terminating the cable means connecting it to the terminal through crimping or soldering using the correct tools and techniques to ensure a strong and reliable connection. For railway signalling cables, termination should be done in a way that provides a secure and vibration-resistant connection, as these cables are subject to constant movement and vibrations.
It’s important to choose the right type of termination for the type of cable and its application. For example, some cables may require a specialized connector or terminal block to ensure proper connection and functionality. Additionally, environmental factors such as moisture, temperature, and vibration should be taken into account, and proper sealing and protection should be used to prevent any damage or corrosion to the termination.
Correct Labelling of Cables
Each cable and conductor should be labelled with its type, length, and purpose, with the labels easily visible and legible. For railway signalling cables, clear and accurate labelling is especially important, given the severe consequences of any malfunction. Thos makes proper labelling quite important for easy identification and troubleshooting in case of any issues.
In addition to proper labelling, cables should be color-coded to indicate their purpose or function. This can help to quickly identify and troubleshoot any issues that may arise. The color-coding scheme should be consistent across all installations and easily understood by anyone working with the cables.
Proper Cable Support & Dressing
Adequate cable support is crucial to prevent cables from sagging or stretching. The supports should be spaced appropriately based on the cable weight, length, and type, and designed to withstand the constant movement and vibrations for railway signalling cables. The type of support used should also be chosen based on the type of cable and its application, with proper sealing and protection used to prevent any damage or corrosion to the supports.
Proper cable dressing refers to the organization and bundling of cables. This should be done in a way that prevents tangling, kinking, or crushing of the cables. For railway signalling cables, proper cable dressing is essential for maintaining the cable’s mechanical and electrical properties, as any damage can compromise the safe operation of the signalling system.
