Recently, INVT GD350 Series High-performance Drives and GD880 Series High-Performance Industrial Drives, developed by INVT independently, have obtained the China Classification Society Certificate of Type Approval (CCS). It marks that the design and application of related inverters meet the requirements of CCS and have the ability to be applied in the field of ships and offshore facilities.

1. What is China Classification Society Certificate of Type Approval (CCS)?

China Classification Society(CCS) is headquartered in Beijing and it is a full member of the International Association of Classification Societies (lACS). It is a classification society of ships, started in 1956 as a non-profit making body in the People's Republic of China to perform classification survey, certification survey and notarial survey of ships including offshore installations, containers and related industrial products both at home and abroad. CCS also conduct statutory work on behalf of the Chinese Government and other flag administrations.

2. What are the approval standards?

* GD350 and GD880 series frequency converters are compliant with Chapter 3, Part Four of China Classification Society Rules for Classification of See-going Steel Ships 2022 and its Change Notices.

* GD880 water-cooled frequency converters are compliant with Chapter 3, Part Four, and Chapter 15, Part Eight of China Classification Society Rules for Classification of Sea-Going Steel Ships 2023 and its Change Notices.

4. What are the characteristics of the marine application environment?

* Anti-salt spray design:
Select corrosion-resistant structural components and coatings, and use automatic spraying equipment to apply three proof paint to the circuit board to ensure that the product will not be affected by salt spray corrosion and will not affect normal use.

* Improved Insulation Performance:
The insulation performance of the product under moisture and dirt is improved, and the insulation resistance is greater than 10MΩ in the face of the harsh environment of high temperature and high humidity at sea.

* Anti-vibration bumps:
The multi-directional, wide-band vibration test and tilt and swing test make the resonance weak point of the product design strengthened, which can easily cope with the low-frequency bump in the wind and waves and the high-frequency vibration generated by the internal power mechanism.

5. What are the application fields of the products?

INVT can provide electric propulsion, shaft power generation, deck machinery, cabin auxiliary equipment and other electric drive solutions for engineering ships (cable laying ships, salvage ships, crane ships, wind power installation ships, rock leveling ships, piling ships, sand dredging ships, dredgers), transport ships (container ships, bulk carriers, ro-ro ships), fishing vessels, cruise ships, and cruise ships.

INVT continues to research new technologies and regulations, and is committed to providing users in the marine industry with a variety of safe and reliable industry solutions such as AC networking, DC networking, and new energy hybrid. The successful certification of marine GD350, GD880 air-cooled inverter and GD880-LC water-cooled inverter is a successful practice of INVT to strengthen the green and intelligent technology of the shipbuilding and offshore industry, and will continue to strengthen the research and development of related technologies for industry solutions in the future to help the high-quality development of the shipbuilding and offshore industry.
