Ports are important transportation infrastructure and a window for achieving an export-oriented economy, providing fundamental support for national economic construction and the development of foreign trade. The major ports in Chinese Mainland have occupied an important position in the world's ports, ranking higher in the world's ports. Their container throughput has ranked first in the world for many consecutive years, becoming the country with the largest port throughput and container throughput and the fastest growth rate in the world.
There are many large-scale equipment concentrated at the port and dock, including intermittent loading and unloading machinery equipment (gantry, tire, truck, bridge and container cranes, unloading machines, etc.), continuous loading and unloading machinery equipment (belt conveyors, bucket elevators, compressed air and hydraulic conveying devices, and pump stations, etc.), power supply and lighting equipment, communication equipment, water supply and drainage equipment, fire prevention equipment, lifting vessels, tugboats, etc Barges and other port operating vessels, underwater transportation pipelines, and other equipment. The lighting, power supply, fire protection, etc. involved in the application of these devices also need the support and guarantee of low-voltage electrical appliances.
Examples of port terminal product applications:
As the main mechanical equipment of the port terminal, the gantry crane generally relies on its operation for loading and unloading of cargo at the terminal. The gantry crane shore power box is the connection point of the wharf gantry crane and the power supply facilities of the Electrical substation, and also the disconnection point of the power supply during the maintenance and troubleshooting of the gantry crane at ordinary times. The reliable operation of the gantry crane shore power box is a necessary condition for the normal operation of the gantry crane. In port loading and unloading operations, the gantry crane often needs to switch positions along a long distance track, but the cable length of the gantry crane is limited. Therefore, it is generally necessary to set up several gantry crane shore power boxes on one side of the track to connect and use electricity at its working location at any time. The gantry crane shore power box is generally equipped with circuit breakers, industrial connectors, industrial sockets, and other devices to protect and power on the gantry crane circuit.
SIWO series circuit breakers, SIWOP series low-voltage distribution boxes, PCE coupling connectors and industrial plug and socket products, with their high waterproof and dust-proof grade, corrosion resistance, high temperature resistance, high mechanical strength and anti-aging product characteristics, have all been important applications in this series of devices.
