Information and application of armored cables: An armored cable, also known as an SWA cable, is a steel-wired cable used primarily for power transmission. It provides enhanced strength and support, making it suitable for various applications including main electricity supply, underground power systems, cable networks, and indoor/outdoor installations. Additionally, armored cables facilitate the installation of electric conductors through a process known as cable ducting.
Information and application of armored cables
Armored cables are utilized in various scenarios, primarily when cables need to be buried underground or installed outdoors. They are crucial in situations where cables pass through underground tunnels or are susceptible to damage during ground openings or repairs, providing protection against such risks.
These cables typically feature an earthed metal sheet that acts as a protective conductor, allowing them to be buried directly underground without additional protection. This characteristic enhances their effectiveness and efficiency in safeguarding cable systems.
Although armored cables are primarily used underground, they are also suitable for above-ground installations. However, precautionary measures should be observed in such cases.
Cables
Armored cables, when installed at heights, should be secured with cleats for stability. Underground installations of armored cables typically have a lifespan ranging from 20 to 50 years, depending on usage since installation.
Guidelines for installation recommend burying armored cables at least 500 mm beneath the ground, with deeper burial preferred below the lowest ground level. Additionally, a route marker tape should be laid around the cables approximately 150 mm below the ground level. These buried cables are steel-wired and undergo cable ducting to include an electric protective conductor.
Zwcables are notable for manufacturing high-quality armored cables and have established a strong reputation among customers. They continuously innovate to enhance the capacity and lifespan of their armored cables, staying competitive in the industry.
XLPE cable
XLPE cables offer several major advantages:
- They are highly efficient in providing protection and support, minimizing additional expenditures and making them cost-efficient.
- The armor of XLPE cables makes them resistant to corrosion, suitable for exposure to moist environments.
- The durable armor provides flexibility and acts as a protective layer for inner conductors, preventing potential damage.
- They can be installed in complex structures where conventional conduits and alternatives are challenging.
- Installation of XLPE cables does not require certified tools or bending tools due to their flexibility, making them time-efficient with minimal labor required.
Overall, the preference for armored cables like XLPE stems from their ability to streamline installation processes by minimizing labor, time, and effort, aligning with human preference for ease and efficiency in tasks.
Conclusion
Armored cables are emphasized as highly beneficial and effective compared to general cables due to their superior protection and efficiency. Unlike general cables, armored cables offer flexibility, making them easier to install and maintain with less labor input required. They also boast a longer lifespan due to their protective electric conductor, minimizing the need for wire ducting and reducing overhead costs. Using armored cables is preferred to avoid the serious and costly outcomes that can result from using less durable and protective ordinary cables.
