The electrical drives and control systems we engineer are designed, built and inspected to a defined set of national and international standards, not to a one-off drawing. The core references cover electrical terminology (GB 2900 series), power semiconductor devices and power-electronic terminology (GB/T 2900.32 / GB/T 2900.33 / GB/T 2900.34), and the rotating-machine rating and performance standard GB 755 together with IEC 60034-17 for inverter-fed induction motors.
Electromagnetic compatibility is treated as a design constraint from the start: electrostatic discharge immunity (GB/T 17626.2) and oscillatory-wave immunity (GB/T 17626.12) shape the cabinet layout, screening and grounding. Low-voltage switchgear and controlgear follow GB 7251 and GB 4720, and product packaging follows GB/T 13384.
Working to these standards consistently is what lets a system designed in our workshop be accepted and run safely on a customer site — the same backbone we apply from a 4800 mm paper-machine sectional drive to a 5360 mm, 2200 m/min rewinder.
