China Circuit breakers Manufacturer, Supplier, Factory

The engineering construction industry has evolved significantly in recent years, driven by societal and economic growth, as well as rapid technological advancements. This has led to a rising demand for more sophisticated and efficient switch equipment that requires minimal upkeep and boasts intelligent features. In response, both domestic and international switch manufacturers are vigorously developing 40.5KV 2500A HV Gas Insulated Switchgear Electrical Switchgear, also known as gas-insulated switchgear (C-GIS). These innovative devices enclose high-voltage components, including busbars, circuit breakers, isolating switches, and power cables, within a protective shell that maintains a lower gas pressure.

72.5KV Outdoor high-voltage SF6 ceramic column single-phase circuit breaker is a three- phase AC 50HZ outdoor high-voltage switchgear, suitable for the control and protection of 72.5KV transmission and transformation system; it can also be used as a contact breaker and opener group. is a three- phase AC 50HZ outdoor high-voltage switchgear, suitable for the control and protection of 126KV transmission and transformation system; it can also be used as a contact breaker and opener group.

The DZ20 series plastic shell circuit breaker (hereinafter referred to as the circuit breaker) is suitable for distribution lines with AC 50Hz, rated current up to 1250A, rated insulation voltage of 660V, rated working voltage of 380V (400V) and below, as overload, short circuit and undervoltage protection for distributed electrical energy, lines and power equipment. Among them, the Y, J, and G type circuit breakers with rated currents of 225A and Y type 400A can also be used to protect motors. Under normal circumstances, the circuit breaker can be used for infrequent switching of lines and infrequent starting of motors. The product meets the standards of JB8589, GB14048.2, and IEC947-2.

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.

The KYN28-12(Z) AC metal-clad switchgear 12KV 1250A Customized Medium Voltage Electrical Switchgear is designed for use in three-phase AC power systems operating at a rated voltage of 12kV and a rated frequency of 50Hz. This equipment is utilized for receiving and distributing electric power, as well as for controlling, protecting, and monitoring electrical circuits.
