Note: The single-core armored cables are used for the D.C. system only. If used for the A.C. system, the magnetic isolation should be applied to the steel armor wires of non-magnetical materials that should be used.

N2XSy and N2XSEY: These are cable types used for medium voltage power transmission and distribution. They indicate different variations of XLPE (cross-linked polyethylene) insulated power cables with copper conductors. The "N2XSy" designation typically refers to a single-core cable, while "N2XSEY" usually represents a three-core cable.

YJV32: This is another cable type used for medium voltage power distribution. It stands for a three-core cable with copper conductors, XLPE insulation, and a galvanized steel wire armor.

Copper Conductor: Copper is a highly conductive metal commonly used for power cables due to its low resistance and excellent electrical conductivity. Copper conductors allow efficient transmission of electrical power.

XLPE Insulated: XLPE is a type of insulation material used in power cables. It stands for cross-linked polyethylene, which offers excellent electrical properties, thermal resistance, and mechanical strength for medium voltage cable applications.
