Product Application
The shell can be made of plastic or stainless steel, with flexible specifications: the inner diameter of the core-through current transformer can be selected from 50 to 60 mm according to the cable specifications; the outer diameter can be selected from 165 to 200 mm due to the different phase spacing of equipment from different GIS manufacturers; the height can be selected from 200 to 400 mm due to the electrical parameter requirements of the project and the space limitations of the equipment cable compartment.
