Feature
1. The busbar adopts heat-shrinkable insulation material or epoxy coating insulation method, optimizes the shape of the electrode, makes the cabinet structure compact, and reduces the area occupied.
2. The cabinet body is made of high-quality cold-bonded steel plate and imported aluminized zinc sheet metal, processed by CNC sheet metal, and connected by high-strength bolts, nuts, and rivet nuts.
3. There are other primary solutions for switchgear equipment, such as cable entry and exit, overhead entry and exit, bus connection, isolation, voltage transformer, lightning arrester, etc.
4. The busbar cabinet, handcart cabinet and cable cabinet are all installed with insulation boards, which greatly improves the insulation level.
5. The interlock between the main switch, trolley, floor knife switch and the cabinet door adopts a mandatory mechanical door lock method to achieve the "five prevention" function.
6. The friendly man-machine interface makes the switchgear operation programmable and stylized, and the operator is clear at a glance.
7. There are more than 160 kinds of main wiring schemes, with strong structural adaptability, which can meet the needs of different users.
