Answer: A transmission network primarily uses large, robust transmission towers and extra-high-voltage lines to span vast areas. Key equipment includes large transformers at substations to step up voltage for long-distance travel, and specialized line traps and insulators designed for immense electrical stress. A distribution network consists of smaller utility poles, street-level transformers, and a web of lower-voltage lines. Our company, Ningbo Changshi, specializes in manufacturing the specific tools and equipment for both these distinct networks, including stringing equipment for overhead transmission and specialized tools for underground cable laying in distribution systems.
