10kV European-type delivery substation is a type of prefabricated kiosk type substation, which is basically the same as the principle of traditional civil engineering electrical rooms. It is to input high-voltage power through high-voltage switchgear, reduce voltage through transformers, and then distribute electricity through low-voltage switchgear.

KYN28A-12/24 metal-clad withdrawable switchgear (hereinafter referred to as KYN28A-12/24 switchgear) is suitable for three-phase AC 50Hz, 3.6-24kV single busbar and single busbar segmented power systems, and is used as a transmission control device for receiving and distributing electrical energy.

The GCK/GCS/MNS low-voltage withdrawable switchgear (hereinafter referred to as the switchgear) consists of two parts: the power distribution center (PC) cabinet and the motor control center (MCC). This device is suitable for control electrical systems with an AC frequency of 50 (60) Hz, a rated working voltage of 660V-690V or less, and a rated current of 4000A or less (where the rated current of the MNS cabinet can reach 6300A).
