Understanding Terminating Steel Wire Armoured Cable Essential Insights

Terminating steel wire armoured (SWA) cables is a critical process in electrical installations, particularly in environments where physical protection of cables is a priority. These cables are commonly used in industrial and underground applications where durability and safety are paramount.

Steel wire armoured cables consist of a core conductor, insulation layer, steel wire armor for mechanical protection, and an outer sheath. The armor protects the cable from physical damage and environmental factors, while the inner conductor is essential for carrying electrical power. However, the proper termination of these cables is crucial to ensure their functionality and safety.

Proper termination of SWA cables prevents issues such as water ingress, electrical shorts, and mechanical stress, which can all lead to cable failure and potentially hazardous situations. Skilled electricians must accurately prepare the cable ends, ensuring that the conductor, insulation, and armor are correctly exposed and terminated. The right tools and fittings are essential to ensure that the terminations maintain the cable's integrity and offer reliable performance.

Steps in Terminating SWA Cables

1. Cutting and Stripping Start by evenly cutting the SWA cable to the desired length. Use a specialized cable cutter to avoid damaging the conductor inner. Remove the outer sheath carefully to expose the galvanized steel wire armor without damaging it.

2. Preparing the Armoring Once the armor is exposed, use appropriate tools to remove a portion of the armor. This step is crucial as it allows for the installation of termination fittings.

3. Installing the Termination Fitting Select a suitable termination fitting that matches the cable size. The fitting often includes a sealing mechanism to prevent moisture ingress. Securely attach the termination fitting over the cable's armor and ensure it's firmly connected to the inner conductor.

4. Cable Glands Utilize cable glands at the termination point. They provide secure entry points for cables into electrical panels, junction boxes, or equipment. Make sure to use a gland designed for SWA cables, ensuring it is appropriately tightened to offer protection against dust and moisture.

5. Testing After termination, conduct electrical tests, including continuity and insulation resistance tests. This step is necessary to guarantee that the installation is safe and compliant with regulations.

Conclusion

Terminating steel wire armoured cables is a process that must be approached with care and expertise. By understanding the importance of proper preparation and the necessary steps involved, electricians can ensure safe and effective cable installations. The right techniques not only prolong the life of the cable but also enhance the safety of electrical systems in various applications. As industries continue to evolve, the demand for reliable and robust cable solutions like SWA cables will grow, underscoring the importance of proper termination techniques in maintaining electrical safety and performance.
