Important Features of KYN58
- The intelligent interface makes the operation more programmable and clearer for operator.
- The special design for the propelling mechanism makes the truck can find the position when pull out or push into the truck.
- The auxiliary service truck can be moved up and down and its width can be adjusted to comply with maintenance requirements of different CB
- The space of cable compartment is larger than before. CT is suspended in the compartment. The height of cable connection is more than 800mm so that it is very convenient to install the cable.
- The earth interlock is simpler and more reliable.
- The shutter is automatically closed and locked mandatorily when the CB is pull out so as to prevent contacting high voltage by misoperation.
- There is reliable interlock between the CB and the door. The CB can be operated only when the door of CB compartment is closed.
