The NAYY’s are unarmoured power and control cables and are most suited for energy supply in fixed installations. Because of the PVC insulation and oversheathing are these cables suitable for fixed installations in buildings, in free air, for direct burial, or in contact with water.
Aerial bundled cables (also aerial bundled conductors or simply ABC) are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor. This contrasts with the traditional practice of using uninsulated conductors separated by air gaps.
Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminium, chosen for its good conductivity, low weight, low cost, resistance to corrosion and decent mechanical stress resistance.
