What conductor and insulation materials are used, and which standards apply?

These cables use stranded aluminium (AL) conductors conforming to Class 2 of IEC 60228, ensuring good flexibility and conductivity. The insulation is cross-linked polyethylene (XLPE), a halogen-free compound classified as type GP8 under IEC 60502-1, which provides high dielectric strength, thermal stability, and resistance to ageing. The overall cable construction meets IEC 60227 and GB/T requirements for low-voltage power wiring, guaranteeing compliance in international projects.
