FAQ
1.What is the core material of this cable?
The conductor is made of aluminium (AL), which offers a lightweight and cost-effective alternative to copper while maintaining good conductivity.
2.What does XLPE stand for in the cable's insulation?
XLPE stands for cross-linked polyethylene, providing excellent thermal resistance, durability, and protection against environmental factors like moisture and chemicals.
3. What does STA SWA signify in the cable structure?
STA SWA refers to steel tape armour (SWA) with a smooth or corrugated design, offering mechanical protection against crushing forces and rodent damage.
4. What is the outer sheath material (PVC) used for?
The PVC sheath provides additional insulation, weather resistance, and durability, making it suitable for outdoor and harsh environments.
5. What are the key applications of this cable?
It is commonly used in industrial settings, power distribution networks, and underground installations where robustness and conductivity are critical.
6.How does aluminium compare to copper in this cable?
Aluminium is lighter and more economical than copper, though it may have slightly higher resistance; it is ideal for large-scale power transmission.
7. What safety features does the XLPE insulation provide?
XLPE insulation ensures high-temperature stability, reducing risks of short circuits and fire hazards, even under heavy loads.
8. Why is steel tape armour (SWA) included in the design?
SWA protects the cable from physical damage, moisture ingress, and electromagnetic interference, ensuring longevity in challenging conditions.
9. What environmental conditions is this cable suitable for?
It is designed for both indoor and outdoor use, withstanding UV exposure, moisture, and temperature variations, thanks to its PVC sheath and XLPE insulation.
10. What are the advantages of using this cable over non-armoured alternatives?
The armour layer (STA SWA) significantly enhances mechanical strength, making it more reliable for buried or exposed installations where external threats are present.
