126KV Outdoor high-voltage SF6 ceramic column circuit breaker is a high-voltage sulfur hexafluoride device used in outdoor electrical systems operating at 126kV. It is designed to manage and safeguard power transmission and transformation networks. This breaker can serve as a switch and disconnection unit when needed. The breaker's innovative arc extinguishing technique involves thermal expansion and auxiliary blowing, and it incorporates a CTB-1 operating mechanism. It complies with the GB1984-2003 standard for AC High Voltage Circuit Breakers and ful specifications of the IEC62271-100:2001 standard for High Voltage Switchgear and Control Equipment Part 100: High Voltage AC Circuit Breakers established by the International Electrotechnical Commission.

40.5KV 4000A Double-break three post disconnector is designed to enhance the efficiency of indoor stations by reducing the distance and station arrangement. Its robust motor performance resistance is achieved through the electric rod's self-rotation and switching structure, along with its self-locking function. This disconnector is capable of withstanding motor, wind pressure, earthquake, and other external forces. Additionally, its sliding rotation method ensures a strong self-clean ability.

The KYN28-12(Z) AC metal-clad switchgear 7.2KV 2500A High Current Electrical Switchgear is designed for use in 12kV-rated three-phase AC power systems operating at a frequency of 50Hz. It is utilized for the reception, distribution, and monitoring of electrical energy, as well as for circuit control and protection.

The SC(B) series epoxy resin dry-type transformer has been meticulously designed to provide exceptional performance and reliability. Its robust construction and explosion-proof features make it a trustworthy choice for a wide range of applications. The compact size and maintenance-free operation of this transformer make it well-suited for direct installation in load centers without any hassle. Furthermore, its encapsulated winding not only ensures a pollution-free environment but also adds to its durability. This transformer incorporates advanced design and casting processes that significantly reduce partial discharge, minimize noise levels, and improve heat dissipation, thereby enhancing its overall reliability. Moreover, with forced air cooling, it can operate reliably under a 125% rated load for extended periods, making it a dependable solution for demanding operational requirements.

This series of miniature circuit breakers consists of a plastic casing, overcurrent release, operating mechanism, contacts, and arc extinguishing system. The shell is made of high-strength and highly flame-retardant plastic. A multi-pole circuit breaker is assembled from multiple single poles, with the release connected by a linkage rod and the handle connected by a linkage cover, ensuring consistency in the on-off of each pole.
