Roxtec sealing solutions ensure electrical safety in substations in the Shanghai Yangshan Deepwater Port Phase IV Project – the world’s largest and most advanced container terminal automation port.
Phase IV of the Chinese port covers 2.23 million square meters. It has a 2,350-meter shoreline and is a strategic hub for the construction of Shanghai International Shipping Center. New technologies, products and materials are used to reduce operation costs and increase efficiency. The Roxtec system is highly appreciated by owners and designers, providing protection for the port substations.
Solution for high cable density
Engineer Weizhi Chen of CCCC Third Harbor Consultants explains why the company specified Roxtec:
"Traditionally we used embedded sleeves for cable entries in substations, but a big number of sleeves in the wall affects the structure and may also lead to water flow from outside trenches into substations. We solve these problems and handle large quantities of cable by using Roxtec seals."
Preventing salty mist
The construction of the port requires stability and durability. To ensure the safety of the structures it is a must to handle the challenge caused by the salty environment of the Shengsi Islands. Small salt fog particles on the surface of electrical equipment may cause corrosion of wire, so the cable entry solution has to resist corrosion and block the salty mist from reaching equipment inside substations.
Roxtec sealing modules and Roxtec GH stainless steel frames are excellent anticorrosion materials.
Certificates of performance
"Roxtec showed us all major testing and certification from the classification society. There is no doubt Roxtec has first-class performance and protection capacity. The sealing system can fully meet the demand for electrical safety for us. It is a reassuring intelligent solution," states Weizhi Chen.
