The KYN28-12(Z) 3.6KV 2500A New Type Of Armored Removable Ac Metal Enclosed Switchgear is designed for use in three-phase AC power systems with a rated voltage of 12kV and a rated frequency of 50Hz. Its primary function is to receive and distribute electric energy, as well as control, protect, and monitor circuits.

The ZW43-12 series 12kv 630A Outdoor Automatical Vacuum Circuit Breaker are designed for outdoor use, with a rated voltage of 12kV and a frequency of 50Hz. These breakers are highly efficient, handling load currents, overload currents, and short circuit currents in power systems with ease. They are particularly suited for substations, industrial and mining establishments, and urban and rural distribution networks, where they provide protection and control, especially in applications that require frequent operation and automation. These breakers comply with several standards, including GB/T1984 for high-voltage AC circuit breakers, GB/T11022 for high-voltage switchgear and control equipment, and D1402 for AC high-voltage circuit breaker ordering technical conditions. Additionally, the circuit breaker can be paired with a controller to form a coordinated device, enabling remote control, monitoring, communication, and adjustment capabilities.

In recent years, with the progress of society, economy, and technology, engineering construction has become increasingly intricate. There is a rising demand for compact switch gear that is low-maintenance and smart. Both local and global switch manufacturers are working on innovative 35KV 1600A Gas Insulated Switchgear Mv Gis, also referred to as gas-insulated switchgear (C-GIS). This type of switchgear encases high-voltage elements like busbars, circuit breakers, isolating switches, and power cables in a shell with reduced gas pressure.

11KV 33KV VCB Vacuum Circuit Breaker designed for three-phase AC 50Hz applications with a rated voltage of 12kV. Suitable for indoor use in various industrial and mining settings, power plants, and substations, it offers reliable control and protection for electrical equipment. Its robust designless installation, either in a switch cabinet or on a handcart, and ensures consistent performance, making it a worthwhile investment for your operations.

The DZ47Z series miniature circuit breaker is suitable for overload and short circuit protection of lines, lighting, and power equipment in DC circuits with a rated voltage of 750V and a rated current of 63A and below. It can also be used for infrequent switching of lines and equipment under normal conditions. The product meets the standards of IEC60898-2 and GB/T14048.2.

BWG Photovoltaic grid connected cabinet is an important component that undertakes centralized inverters and step-up transformers or AC combiner box step-up transformers. The incoming line of this photovoltaic grid connected cabinet uses a short-circuit breaker input or direct input, and the output uses a circuit breaker or load isolation switch. The busbar is connected with electroplated or purified wire, and provides secondary lightning protection. The maximum rated voltage of the system is AC690V, and the protection level is | P40 indoors and | P65 outdoors; The cables for secondary measurement and control include cables with a current greater than 2.5mm2, cables with a voltage of 1.5mm2, and cables with a control voltage greater than 1.0mm2.
