Product Overview
The JHK iPV550 AC armored removable switchgear is a metal cabinet designed and manufactured by our company,
It is used for single-bus or segmented three-phase AC power distribution systems with a voltage of 3-12 kV. It is widely used in power plants, substations, industrial and mining enterprises, as well as in urban construction as a complex switch for receiving and distributing electric energy. The cabinet width is 550 mm, so it takes up a small area and is characterized by a compact design, low height and reliability.
