Scope

This standard specifies the types, basic parameters and dimensions, technical requirements, test methods and inspection rules, as well as marking and packaging of marine flameproof three-phase asynchronous motors used in explosive environments on steel sea-going ships, offshore mobile drilling ships and fixed platforms. requirements. The explosion-proof performance of this series of motors complies with the regulations of GB 3836.1 and GB 3836.2, and is made of explosion-proof type. The explosion-proof marks are dⅡAT4, dⅡBT4 and dⅡCT4. It is suitable for places with explosive mixtures of flammable gas or steam and air in Class IIA, Class IIB and Class IIC temperature groups T1 to T4 respectively. This series of motors complies with my country's "Code for Classification and Construction of Sea-Going Steel Ships", "Code for Classification and Construction of Offshore Mobile Drilling Ships" and "Code for Classification and Construction of Offshore Fixed Platforms". Requirements not specified in this standard shall comply with the provisions of GB 755.
