To satisfy the connect and disconnect frequently of DC component in Marine drilling platform, Hande design and research a series monodirectional and duplex. The contactor use the module design

To meet the needs of the offshore drilling platform's DC power system components to achieve interchangeability, Hande independently developed monodirectional and bidirectional DC contactors ranging from 1100A to 3000A. The contactor adopts an alternative design, which can assemble the number of series circuits required by the customer and the exchange form (normally open, normally closed and conversion) required by the customer with fewer parts; this series of products have high series breaking voltage ranging 750V to 1000VDC, and the mechanical lifespan can reach 2 million times. The product is mainly used for high-power driving occasions of offshore drilling platforms.

System characteristics of ZQ DC contactor:

(1) Two-way breaking capacity

(2) 1800A and 3000A continuous current carrying capacity at 55℃

(3) Rated 5000A breaking current capacity under 750VDC withstand voltage

(4) The electrical clearance and creepage distance meet the application under 1500VDC

System Characteristics of FQ DC contactor :

(1) Two-way current carrying capacity

(2) 1100A continuous current carrying capacity at 55℃

(3) The electrical clearance and creepage distance meet the requirements of applications below 1000VDC
