FAQs
Is the product suitable for marine use?
Adaptation, specially optimized for anti vibration and anti salt spray in ships, certified by classification societies, can be used for power distribution in ship decks, engine rooms, and other parts to resist vibration and marine salt spray erosion during ship navigation.
How to ensure the installation and after-sales service of overseas projects?
Provide English installation manuals and video guidance, dispatch technical personnel for overseas on-site debugging, and set up spare parts warehouses in key areas overseas to ensure timely after-sales response and solve export project operation and maintenance problems.
Can it be compatible with temporary use of 6kV distribution network system?
Long term compatibility is not recommended. The insulation parameters and conductor specifications of 6.6kV products are designed for 6.6kV, and long-term use in 6kV systems will reduce insulation redundancy and operational efficiency. If cross voltage use is required, an adapted version needs to be customized in advance.
How long can the salt spray resistance of the product last?
After special anti-corrosion treatment, it can maintain salt spray resistance for more than 10 years in marine atmospheric environment. Regular cleaning of the cabinet surface is sufficient without additional anti-corrosion maintenance.
What languages does the intelligent controller support?
Standard configuration includes bilingual Chinese and English, with the option to add Spanish, French, Arabic, and other languages as needed to meet the operational needs of projects in different countries. The interface is simple and easy to use.
