In long-distance transportation and cross-regional power networks, power distribution cabinets play a critical role in power distribution, control, and protection. Whether in highway service areas, logistics hubs, or cross-regional power networks, power distribution cabinets provide stable and efficient power support, ensuring the continuity of long-distance transportation and power transmission. Their core roles include power distribution, fault protection, intelligent management, and energy efficiency, offering stable, safe, and efficient power support for cross-regional transportation and power transmission. They are the "central hub" of long-distance power networks.
