China Outdoor high voltage isolation switch Manufacturer, Supplier, Factory

126KV Outdoor high-voltage SF6 circuit breaker is a high-voltage, three-phase AC 50Hz switchgear designed for outdoor use, ideal for controlling and protecting 126kV transmission and transformation systems. Additionally, it can function as a contact breaker and opener group. This circuit breaker utilizes an intelligent arc extinguishing principle that combines thermal expansion with auxiliary blowing, and features a CTB-1 operating mechanism. It meets the standards outlined in GB1984-2003 for AC high-voltage circuit breakers and is compliant with the International Electrotechnical Commission's IEC62271-100:2001 standard for high-voltage AC circuit breakers and control equipment.

The CFB3 series miniature circuit breaker is suitable for overload and short circuit protection in AC 50/60Hz, rated voltage up to 230V/400V, and rated current up to 125A lines. It can also be used for infrequent on/off operations of the line under normal conditions. The CFB3-63 series circuit breaker is equipped with accessories such as CFB3-F auxiliary contacts, CFB3-FB auxiliary alarm contacts, CFB3-FL shunt release, CFB3-QY undervoltage release, CFB3-GY overvoltage release, CFB3-GQY overvoltage release, etc., providing convenience for the intelligent control of smart buildings. Overvoltage, undervoltage, and overvoltage/undervoltage are electronic release devices that are assembled and combined with circuit breakers or residual current circuit breakers. They are suitable for AC 50Hz/60Hz circuits with a rated voltage of 230V, and are used to protect against overvoltage, undervoltage, and overvoltage caused by line faults, avoiding damage to electrical equipment or inability to function properly due to fluctuations in grid voltage. The circuit breaker has an isolation function. Compliant with standards: GB/T10963.1, IEC60898-1, GB/T20645.

In recent years, with the advancement of technology and the growth of society and the economy, engineering construction has become increasingly intricate. There is a rising demand for compact switchgear that is low-maintenance and smart. Both local and global switch manufacturers are currently engaged in the development of 40.5KV 630A Sf6 Sulfur Hexafluoride Filled Gas Insulated Switchgear, which are also referred to as gas-insulated switchgear (C-GIS). This type of switchgear houses high-voltage elements like busbars, circuit breakers, isolating switches, and power cables in a container with reduced gas pressure.

The New Armored Removable AC Metal-Enclosed Switchgear, a testament to advanced switchgear technology, is specifically crafted for three-phase AC power systems with a rated voltage of 35kV. It accommodates rated currents ranging from 630a to 3150a, and operates at a frequency of 50Hz. This cutting-edge equipment not only facilitates the efficient transfer and distribution of electric energy but also offers robust control, protection, and monitoring capabilities for electrical circuits, ensuring optimal performance and reliability.

KYN28A-24 (SDK1-24) armored removable AC metal-enclosed switchgear 24KV 3150A High Current Electrical Switchgear (from now on referred to as switchgear) is suitable for indoor three-phase 50/60Hz, rated voltage 24kV power systems. It is mainly used in power plants. In substations, industrial and mining enterprises, and high-rise buildings, it receives and distributes electric energy and controls, protects, and monitors circuits.

12KV Indoor Medium Voltage Vacuum Circuit Breaker is a high-voltage solution for indoor applications, featuring a rated voltage of 12KV and a frequency of 50Hz for three-phase AC systems. This product, known for its reliability, complies with the GB1984-89 standard. The design of this product is available in two configurations: the switch body and operating mechanism are integrated, and a modular version where the switch body and operating mechanism are separate. The integrated design is denoted as the ZN28-12 type, while the modular design is referred to as the-12 type, suitable for use in fixed switches such as GG-1A(Z) and XGN2A10(Z). This product can be paired with DC electromagnetic types CD17 and CD10A, as well as spring energy storage types CT17 and CT19.
