What are the key components of an electricity transmission system?

2025-08-09

The modern electricity transmission system, often called the "power grid," is a sophisticated network of interconnected components. The main parts include:

  • Power Plants: Where electricity is generated.

  • Transmission Substations: Facilities that use transformers to increase (step-up) or decrease (step-down) the voltage of electricity.

  • Transmission Lines: The high-voltage lines, both overhead and underground, that carry large amounts of power over vast distances.

  • Transmission Towers & Pylons: The structures that support overhead transmission lines.

Our company, Ningbo Changshi, specializes in providing the tools and equipment necessary to build, maintain, and upgrade all these components, from conductor stringing equipment for overhead lines to cable pullers for underground projects.
