2026-04-11
- Industry standards and safety regulations：According to the newly released "Technical Standard for Safety of Temporary Electrification on Construction Site of Building and Municipal Engineering JGJ/T46-2024",the power distribution system should implement three-level power distribution,that is, set up a general Distribution Box, a sub-distribution box, and a switch box.The main distribution box should be set up close to the power source,the sub-distribution board should be located in the area where electrical equipment or loads are concentrated,and the distance between the distribution box and the switch box must not exceed 30 meters,The horizontal distance between the switch box and the fixed equipment should not exceed 3 meters.
- Trends in intelligence and technological innovation:Distribution boxes are moving towards intelligentization,intelligent distribution boxes integrating Internet of Things technology have emerged, featuring remote control, energy consumption monitoring, and other functions, and are regarded as one of the future development directions in the industry.
- The market for high-voltage power distribution units (PDU) in electric vehicles is experiencing rapid growth:As one of the core components of electric vehicles, the high-voltage power distribution unit (also known as PDU) is responsible for the rational distribution of electric energy from the traction battery,enhance safety and space utilization.In 2021, the market size of China's new energy vehicle PDU was 7.742 billion yuan, and it is expected to grow to 12 billion yuan by 2026.The main participants include high-voltage connector enterprises, motor and electronic control manufacturers, power battery enterprises, and affiliated companies of original equipment manufacturers (OEMS).
- Application scenario expansion and industry integration:Distribution boxes are not only used in traditional buildings and industrial settings,it also plays a key role in the installation of charging piles.
