Inhouse product
ASHFLEXI 3 × 16 mm² CCA/PVC/PVC – White is a three-core electrical cable specification. The code indicates three conductors, each with a nominal cross-sectional area of 16 mm², with PVC insulation and an outer PVC sheath.
Important: ASH Cables' official ASHFLEXI datasheet lists a copper-conductor version (CU/PVC/PVC). I couldn't confirm that the exact CCA version you listed is an official ASH Cables specification, so check the cable printing or product label before ordering.
