A 33 kV overhead line is a medium-voltage electrical line used to transmit power from larger substations to local distribution points. Its components are specifically designed to handle this voltage and the greater mechanical loads that come with it. Key components include:

• Line Supports: These are often robust steel poles or concrete poles (like PSC poles) that are stronger and taller than those used for lower-voltage lines. This provides the necessary ground clearance and stability for the heavier conductors.

• Conductors: The wires themselves are typically made of ACSR (Aluminum Conductor Steel Reinforced), which provides a high strength-to-weight ratio. These conductors have a larger cross-section than those on 11 kV lines to handle higher current and reduce power loss over longer distances.

• Insulators: To prevent current from arcing to the support structures, a series of pin-type, post-type, or suspension disc insulators are used. For 33 kV lines, a greater number of insulator discs or a more robust design is required compared to 11 kV lines.

• Line Hardware: A variety of fittings, clamps, and cross-arms are necessary to securely hold the conductors and insulators to the poles. These accessories are larger and stronger to withstand the increased tension of a 33 kV line.
