Structure feature
1. The enclosure is made of aluminium-zinc plated steel sheet or cold rolled iron sheet after processed by CNC machine and multi-bending, so guarantee advantages of high precision and strong corrosion preventions.
2. The complete panel is divided into four separate compartments, those are busbar compartments, handcart compartment,cable compartments and relay compartment. It is equipped with five protection lock device.
3. There is a exhaust channel spreads to the top in every compartment. The coping will open automatically to release pressure and guarantee the security of operator.
4. There is a valve mechanism among handcart compartment, busbar compartment and cable compartment. The valve closes automatically when the handcart is drawn out, then cover the main static contact to guarantee the security of maintenance man.
