XL-21 power cabinet

XL-21 power cabinet is widely used in power plants and industrial and mining enterprises. It is used for power or lighting distribution in power distribution systems such as three-phase three-wire, three-phase four-wire, three-phase five-wire and other power distribution systems below three-phase AC 500. It is installed against the wall, operated in front of the screen, and inspected in front of the screen; the box body is a fully enclosed structure, which is assembled from C profiles or 8MF profiles. A new type of rotary load isolation switch is used in the box. It can be operated with load. The front door is equipped with voltage and current indicating instruments, as well as main components such as signal lights, buttons, and transfer switches. This distribution box adopts self-designed new components, with compact structure, elegant appearance, convenient maintenance, and a variety of wiring schemes for users to choose from. It is an ideal product to replace the old XL-21 power box.

GGJ low voltage reactive power compensation device

Because the device can effectively improve the power factor of the electrical load, reduce the line loss, and improve the actual load capacity of the transformer. It has significant energy-saving effect. At the same time, the use of specific reactors in the system can also effectively prevent harmonic amplification and effectively absorb most of the harmonic currents, so that the total harmonic voltage distortion rate limit and the harmonic current content limit of each order meet the requirements. National standards to achieve the purpose of harmonic control. However, if an ordinary contactor is used to switch the capacitor bank, it will bring large inrush current, slow compensation time, high maintenance cost and short service life. Therefore, we recommend users to give priority to the following occasions. Consider using dynamic var compensation. For example, in the low-voltage power grid of industrial and mining enterprises' substations, production workshops and civil buildings, it is especially suitable for transmission and distribution systems with frequent load changes and unstable reactive power. This product complies with: GB/T15576-2008 "Low-voltage complete sets of reactive power compensation equipment", IEC60439 "Low-voltage complete sets of switchgear and control equipment" and other standards.

GGD AC low voltage fixed switchgear

GGD AC low-voltage fixed switchgear is suitable for power distribution systems with AC 50HZ, rated working voltage 380V, and rated working current up to 3150A for power users such as power plants, substations, factories and mines. for distribution and control. GGD AC low-voltage fixed switchgear is a new type of low-voltage power distribution cabinet designed according to the requirements of the competent superiors of the Ministry of Energy and the majority of power users and design departments, and based on the principles of safety, economy, rationality and reliability. The product has the characteristics of high breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, series, strong practicability, novel structure, high protection level, and can be used as a replacement product for low-voltage switchgear. GGD AC low-voltage fixed switchgear complies with EC439 "Low-voltage switchgear and control equipment", GB7251 "Low-voltage switchgear" and other standards.

GCK low voltage withdrawable switchgear

GCK low-voltage withdrawable switchgear is composed of power distribution center (PC) cabinet and motor control center (MCC). In the power distribution system with current to 3150A, it is used for power conversion and distribution control of power distribution, motor control and lighting power distribution equipment.

GCS low voltage withdrawable switchgear

GCS low-voltage withdrawable switchgear is used for power distribution systems in power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries. In large power plants, petrochemical systems and other places with a high degree of automation and requiring interface with a computer, the three-phase AC frequency is 50(60)Hz, the rated working voltage is 380V(400V), (660V), and the rated current is 4000A and below. It is a low-voltage complete power distribution device used for power distribution in power generation and power supply systems, centralized control of motors, and reactive power compensation.

MNS low voltage withdrawable switchgear
