EI Supporter
|
|
|
It can be used as the insulating supporter for mounting instruments to Distribution Panel Board, Control Board, Rectifier Board, and the wiring of Bus bars and Wires. |
|
1) The load bearing property is mush superior than the usual type and then it can be used widely.
2) Good insulating property, light weight and not easily broken |

Junction Unit of High Voltage Epoxy Resin Insulator with Olastic cover
|
Example of installation
|
|
It can be used as the insulating supporter for mounting instruments to Distribution Panel Board, Control Board, Rectifier Board, and the wiring of Bus bars and Wires. |
|
1) It is easily to attach the terminals as the plastic cover is vertical structure.
2) The emerged junction point can be seen clearly as the cover is transparent.
3) It is safer as the emerged junction point is covered with the cover when touched. |
Test Results |
1) No flush over will occur between the metal terminal and the metal attached to the surface of the cover at AC 22 kV 1 min..
2) No electrical breakdown will occur against the cover itself at AC 22 kV 1 min.
3) Withstand load: 180 kgf |
