The GCS-type low-voltage withdrawable switchgear is suitable for power distribution systems in industries such as power generation, petroleum, chemical engineering, metallurgy, textile manufacturing, and high-rise buildings. In applications with a high degree of automation—such as large power plants and petrochemical complexes—that require interface with computer systems, it serves as a low-voltage complete set of distribution equipment for power distribution, centralized motor control, and reactive power compensation in three-phase AC systems with a frequency of 50 Hz, a rated operating voltage of 0.4 kV, and a rated current of 2,500 A or less.
The YZ-type AC low-voltage distribution cabinet is a new-generation low-voltage switchgear designed in accordance with the principles of safety, economy, rationality, and reliability. It is widely used in AC power distribution systems with a frequency of 50 Hz, a rated operating voltage of AC 380 V, and a rated current of up to 2,000 A.
The GCK low-voltage withdrawable switchgear is widely used in power distribution centers (PC) and motor control centers (MCC) of power plants, substations, industrial and mining enterprises, and high-rise buildings, serving as a complete low-voltage distribution system for power distribution, centralized motor control, and reactive power compensation in AC systems with frequencies of 50–60 Hz, rated operating voltages of 660 V and below, and rated currents of 4,000 A and below. In three-phase three-wire or three-phase four-wire systems, it is specifically employed for substation switching, feeder distribution, and dedicated motor applications within low-voltage distribution networks. While maintaining electrical performance that exceeds that of comparable products, the GCK low-voltage withdrawable switchgear features increased capacity and enhanced mechanical strength, along with an advanced structure, aesthetically pleasing appearance, high degree of protection, high safety and reliability, and convenient maintenance; it is thus well suited as a replacement and upgrade solution for conventional low-voltage switchgear assemblies.
The MNS drawer cabinet, also known as the MNS low-voltage switchgear or MNS switchgear, is a specific type of low-voltage drawer cabinet. This product features a compact design, high degree of structural versatility, and flexible assembly, thanks to its standardized modular construction. It is a new-generation, low-voltage, withdrawable MNS switchgear that is safe, economical, rational, and reliable. Key characteristics include high breaking capacity, excellent dynamic and thermal stability, flexible electrical configuration options, and a high protection rating. This equipment complies with IEC 439, VDE 660 Part 5, the national standard GB 7251-87 “Low-Voltage Switchgear and Control Equipment,” and the industry-specific standard ZBK 36001-89 “Low-Voltage Withdrawable Switchgear and Control Equipment.”
