Description of DC quick-change charging socket

SKZ series DC quick-change charging sockets are installed on electric vehicles. By cooperating with the DC charging gun, the DC charging function can be realized. The products meet GB/T 20234.3-2015 and comply with RoHS requirements.

Features of DC quick-change charging socket

  • The 250A power-on temperature rise is small and stable: the temperature rise is lower than 50K during 500 power-on cycles and 10,000 plug-and-pull times.

  • Low after-sales maintenance costs: when the power terminals are worn, dirty, or the insulating column is broken, it can be quickly replaced, and the product is easy to maintain.

  • High product assembly efficiency: parts can be pre-assembled, semi-finished products can be put into storage, modular material preparation, batch operations can be realized, and the delivery cycle can be shortened.
