The ZW7-36 series 40.5KV 3150 amp Outdoor ceramic column HV Vacuum Circuit Breaker is engineered for out door in a three-phase alternating current 50Hz high-voltage switchgear arrangement. It is capable of handling a range of electrical currents, including load, overload, and short-circuit currents, in power distribution and transmission systems operating at 36KV

The KYN28-12(Z) 7.2KV 1250A Commercial Switchgear Power Distribution Cabinet is designed for three-phase operating at a rated voltage of 12kV and a rated frequency of 50Hz. Its primary function is to manage the reception, distribution, and monitoring of electrical energy as well as to control and protect circuits.

The 24KV 1250A outdoor sf6 medium voltage circuit breaker is designed for controlling and protecting 24KV transmission and transformation systems, operating at 50Hz and suitable for outdoor use. Additionally, it can function as a connecting circuit breaker and an integrated opening and closing device. This circuit breaker employs an intelligent arc-quenching system based on thermal expansion and auxiliary blowing, paired with a CT10 spring operating mechanism. Furthermore, it meets the standards set by GB/T1984-2014 for AC high-voltage circuit breakers and adheres to the IEC62271-100:2001 international standard for high-voltage AC circuit breakers and control equipment.

HXGN-12 switchgear Modular AC metal enclosed Ring main unit RMU is a high-voltage AC complete set designed for a three-phase AC ring network, terminal distribution network, and industrial electrical equipment. It is suitable for power distribution and protection and can be installed in substations. It complies with national standards GB3906 and IEC60298, as well as DL/T402 and DL/T404 standards, and meets the requirements of "five-proof" blocking.

The Drawer type low-voltage switchgear ensures that each functional unit is distinct from the busbar or cable, creating three separate areas for efficient power distribution. This design also incorporates isolation measures between functional units, contributing to the overall reliability and safety of the switchgear. As a result, drawer-type switchgear is widely used in industrial and mining enterprises, high-rise buildings, and centralized control distribution centers that require high power supply reliability. The switchgear's closed steel plate shell houses withdrawable drawers containing electrical components for incoming and outgoing circuits, allowing for easy maintenance and customization.

The 145KV Outdoor high-voltage SF6 open type combination electrical appliances stands out as an integrated electrical device specifically designed for high-voltage power transmission and distribution systems. Its unique composition includes circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, and surge arresters, all enclosed in a metal housing filled with sulfur hexafluoride (SF6) gas, a highly effective insulating medium.
