- SA: Aluminum Screen
- 2Да: Sheath is PE
- -S: Steel core
- 6/10kV NA2XSA2Y-S
- 8.7/15kV NA2XSA2Y-S
- 12/20kV NA2XSA2Y-S
- 18/30kV NA2XSA2Y-S
NA2XSA2Y-S Cable Construction
The NA2XSA2Y-S cable is meticulously engineered to withstand the rigors of high-voltage transmission and distribution. Its core comprises a stranded copper conductor, chosen for its excellent conductivity, ductility, and corrosion resistance. Surrounding the conductor is a semi-conducting layer, which ensures uniform electrical stress distribution across the insulation.
The XLPE insulation layer is the heart of this cable, providing exceptional dielectric strength, термостойкость, and mechanical toughness. This material is cross-linked during the manufacturing process, enhancing its chemical and environmental stability. An additional semi-conducting layer covers the insulation, further optimizing electrical performance.
The metallic screen layer, typically made of copper wires or tapes, serves as a grounding or shielding mechanism, protecting against electromagnetic interference and providing a path for fault currents. This layer is then covered by an inner sheath of PVC or other suitable material, providing additional protection and mechanical strength.
