Product Application
The LSZ series three-phase integrated current transformer is installed at the root of the inlet and outlet bushings of the fully insulated and fully sealed ring main unit and the pole-mounted switchgear, fixed with bolts, and integrated with the complete set of equipment. The overall structure is compact, light, and easy to install. All installation work is completed in the factory of the complete set of equipment. No secondary installation is required on site. When
the complete set of equipment is modified, there is no need to remove the cable accessories, which reduces the
modification cost. It is neat and beautiful, and maintenance-free when leaving the factory. It can provide a variety of phase sequence and zero sequence current measurement/metering and protection combination solutions, which have been used in compact fully insulated and fully sealed ring network switchgear and pole-mounted switches and other electrical equipment.
