Our Professional Answer: A robust distribution network is composed of several key components working together to ensure reliable power delivery. The primary components include:

• Distribution Substations: These are the critical hubs where electricity is stepped down from high transmission voltages to medium distribution voltages. They contain transformers, switchgear, and protective relays.

• Primary Feeders/Distribution Lines: These are the main lines that carry medium-voltage power away from the substation, often supported by wooden utility poles for overhead systems or buried as cables for underground systems.

• Distribution Transformers: These are pole-mounted or pad-mounted transformers that perform the final voltage step-down to a safe level for consumer use.

• Service Drops/Cables: These are the final connections that deliver low-voltage power directly from the local transformer to the customer’s meter.

As a leading manufacturer, Ningbo Changshi supplies a wide range of tools and equipment essential for building and maintaining these components, including our specialized underground cable laying equipment and a variety of overhead tools and accessories.
