In Denmark, the electrical system operates on 220V at 50Hz. The country uses electrical plugs of type E and type K. The Type K electrical plug looks like Type E but with a ground pin instead of a hole on the plug, and a hole instead of a pin on the socket. So, it has two round pins and one spade grounding pin.
