The electricity supply chain is a multi-stage process that ensures power is delivered from the source to the end-user. It is typically broken down into four main stages:

1. Generation: This is where electricity is produced at power plants from various energy sources, such as coal, natural gas, nuclear, solar, or wind.

2. Transmission: The generated electricity's voltage is increased at a substation for efficient transport over long distances via high-voltage overhead power lines or underground cables.

3. Distribution: The electricity is then received at local substations, where the voltage is lowered to a safe level for delivery to homes and businesses through a network of smaller poles and wires.

4. Consumption: This is the final stage where the electricity is used by consumers for lighting, appliances, and industrial processes.

At Ningbo Changshi, our tools and equipment are central to both the transmission and distribution stages of this critical process.
