Product advantages
Leading technology
- Standard anti-corrosion and salt spray environment scheme, meet the strict environmental requirements of the site
- Locking tapping screws and 8.8 high strength bolts for connection, so the cabinet installation accuracy is high
- Strong versatility, can be configured with various brands of circuit breakers at home and abroad, such as CHINt NXM series, ABB Tmax series, Schneider NSX series, etc
- High breaking ability, good dynamic thermal stability, advanced structure, arbitrary combination of various scheme units
- Compact design, can accommodate more functional units in a smaller space
- High strength resistance type engineering plastic component or metal partition, with CT1300 grade above leakage performance
Cabinet put oneself in another's position
- The whole use of 2-3mm high quality cold rolled hot dip galvanized sheet
- Laser CNC equipment cutting, drilling, bending, ensure processing accuracy
- External electrostatic epoxy powder coating, 50 years of paint
- Mold size, hole size and equipment spacing are modular (module E=25mm)
Functional units
- Can be composed of protection, operation, conversion, control, adjustment, determination, indication and other standard units, optional assembly
- More than 200 kinds of assemblies can form different schemes of cabinet frame structure and drawer units
Busbar system
- Three-phase four-wire system or three-phase five-wire system
- High quality three phase tinned bus copper bar, high mechanical strength, good heat dissipation
- The horizontal bus is installed on the top of the cabinet, the N line can be installed on the top or the bottom of the cabinet, and the PE line is installed on the bottom of the cabinet
Processing and assembly
- Dust-free workshop to ensure insulation
- Assembly workers must be trained for at least 6 months
- Automatic terminal crimping machine for secondary wiring to ensure reliable wiring
- Bolt reinforcement using power tools to ensure proper torque
- The copper busbar is CNC cutting, punching and bending to ensure accuracy
- All kinds of experimental tests before delivery, to ensure the normal operation of equipment
