GGD series fixed switchgear advantages
> Leading technology
- High breaking capacity, good dynamic and thermal stability
- Standard anti-corrosion and salt spray environmental plan to meet the stringent environmental requirements of the site
- High breaking capacity, good dynamic and thermal stability
> Cabinet put oneself in another's position
- The overall use of 2-3mm high quality cold rolled hot dip galvanized sheet, local welding
- Laser numerical control equipment cutting, drilling, bending, to ensure the processing accuracy
- There are different number of heat dissipation slots at both ends of the cabinet body to form a natural ventilation channel to achieve the purpose of heat dissipation
- The exterior is coated with electrostatic epoxy powder, which will not take off paint for 50 years
- Molding size, hole size and equipment interval are modularized (modulus E=20mm)
> Functional units
- The instrument doors with electrical components are connected to the frame by multiple strands of flexible copper wire
- The mounting parts in the cabinet are connected with the frame with knurled screws. The whole cabinet forms a complete grounding protection circuit
> Busbar system
- Adopt three-phase four-wire system or three-phase five-wire system
- High quality three-phase tin bus copper bar, high mechanical strength, good heat dissipation
> Processing and assembly
- Dust-free workshop to ensure insulation
- Assembly workers have been trained for at least 6 months
- The secondary connection is automatic terminal crimping machine to ensure reliable connection
- Use power tools to ensure proper torque for bolting reinforcement
- The copper bus is CNC cutting, punching and bending to ensure the accuracy
- All kinds of experimental tests before delivery to ensure the normal operation of the equipment
