This 12/20(24)kV power cable is designed for higher medium voltage applications, utilizing compacted copper conductors and XLPE insulation to support stable electrical performance under increased voltage stress.
Copper tape screening is applied to manage the electrical field within the cable structure, while the armored design contributes to physical protection during installation and operation.
The cable is available in both single-core and multi-core constructions, allowing adaptation to different system layouts and installation requirements.
