GB/T 4988-2016 in English

GB/T 4988-2016 Standard Overview

GB/T 4988-2016 "Rated frequency, rated voltage and rated current of electrical products for ships and offshore installations" is a core standard applicable to electrical products for ships and offshore installations, which mainly stipulates the rated parameters of the equipment. Compared with the 2002 version, this revision has made important adjustments to the AC voltage parameters and expanded the scope of application.

Comparison of Standard Frameworks

Background of the formulation of the standard

With the development of navigation technology, ships are increasingly dependent on power systems, especially the popularization of high-power electrical appliances and complex electronic equipment. The old version of the standard can no longer meet the technical requirements of modern ships in some parameters, so revision has become inevitable.

Technical evolution analysis

From GB/T 4988-2002 to GB/T 4988-2016, the main progress of the standard is reflected in:

• Expanded scope of application: More equipment types have been added, such as intelligent control systems and high-voltage equipment.
• Parameter refinement: The rated voltage classification has been refined, and new frequency standards have been introduced.
• Safety improvement: By clarifying the voltage parameter range, safety hazards caused by improper parameters can be reduced.

Implementation suggestions

For related companies:

1. Update product standards in a timely manner to ensure that the design of new products meets the latest standard requirements.
2. Evaluate existing equipment and modify or replace it if necessary to meet the new version of the standard.
3. Strengthen employee training to improve the understanding and implementation of the new standard.
