The 2YSLCY composite connection cable features XLPE (cross-linked polyethylene) insulated power cores combined with PVC insulated screened control cores in a common cable — the "2Y" prefix indicating XLPE insulation for the power conductor elements. XLPE insulation provides higher continuous current ratings, improved thermal ageing resistance, and superior high-temperature performance compared to PVC insulation, enabling the power cores to carry higher currents within the same physical conductor cross-section. The tinned copper braid screen (CY) covers the full cable bundle for EMI shielding of the control cores. Rated 0.6/1kV power, 300V control; available in standard composite configurations.
