The ship’s power distribution system is the “heart” of the ship, and its stability directly affects navigation safety. As the core products of Zhoushan Shunfan Ship Electrical Appliance Factory, the ship’s main distribution board and emergency distribution board strictly follow multiple technical specifications such as the International Electrotechnical Commission (IEC), Chinese National Standards (GB), and British Standards (BS). Taking the IEC 60092 series standards as an example, they impose strict requirements on the insulation performance, temperature rise limit, and short-circuit withstand capacity of electrical equipment. Shunfan products ensure long-term full load operation at an ambient temperature of 45 ℃ by optimizing the copper busbar current carrying design and using flame-retardant engineering plastics.

Certification by the nine major classification societies is the passport for ship electrical equipment to enter the global market. The certification process of organizations such as American Bureau of Shipping (ABS), French Bureau of Shipping (BV), and China Classification Society (CCS) covers three major stages: material testing, type testing, and factory audit. Shunfan’s distribution board demonstrates three major advantages in certification:
1. Salt spray corrosion resistance: The high humidity environment in the coastal city of Zhoushan naturally verifies the protection level of equipment (IP56 or above);
2. Electromagnetic compatibility: Through EMC testing, avoid interference with ship communication systems;
3. Fast fault isolation: Adopting a segmented busbar design, the fault circuit can be cut off within 0.1 seconds in case of a short circuit.
