Medium-Voltage/Low-Voltage Box Type Substation

Medium/low voltage box-type substation is also called medium/low voltage complete substation. Sometimes customers also call it European box substation and American box substation. It is also called metal armored assembly substation and micro substation. It belongs to distribution substation (MDS) and is directly Provide electricity to users. High input voltages are typically 35kV, 24kV and 10kV. The main equipment includes high-voltage switch cabinet (high-voltage room), distribution transformer (transformer room), and low-voltage distribution device (low-voltage room). Especially suitable for urban network construction and transformation. According to the high-voltage power supply mode, there are "terminal type" box-type transformer and "ring main unit" box-type transformer. Depending on the design, it can be divided into environmentally friendly modular substations, intelligent/compact box-type substations, and intelligent integrated substations.
