The European style European style cable junction box cable branch box is a widely used cable engineering equipment in power and distribution network systems in recent years. Its main feature is bidirectional door opening, using through wall sleeves as connecting busbars, with significant advantages such as clear arrangement of small length cables and no need for large span crossing of three core cables. The cable joints used comply with the DIN47636 standard. Generally, a spiral fixed connection cable joint with a rated current of 630a is used

The advancement of society, economy, and technology has led to the escalating intricacy of engineering construction in recent years. This has resulted in a growing demand for compact, maintenance-free, and intelligent switch products. Domestic and foreign switch manufacturers are actively developing 12KV 630A MV Gas Insulated Power Distribution Switchgear (C-GIS), also known as gas-insulated switchgear. Gas-insulated switchgear is a type of equipment that encloses high-voltage components like busbars, circuit breakers, isolating switches, and power cables within a shell, which maintains a lower gas pressure.

The FZW28-12F 12KV Outdoor Demarcation Vacuum Load Break Switch LBS, as the boundary, is designed for outdoor installation on columns and can be operated manually or electrically. This switch utilizes the Corporation's VSP5-12 technology, making it a maintenance-free load switch. It uses vacuum arc extinguishing and SF6 gas for ground and phase insulation. This product conforms to the standards of GB3804 for high voltage AC load switch and GBT high voltage switchgear and control equipment.

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.

35kv Medium voltage Outdoor cable branch box is a supporting equipment for the cable transformation of the State grid, which is decorated in outdoor, indoor or buried places, and can connect the power cable with the box transformer, load switchgear, negative one-fusion combination electrical cabinet, ring network power supply unit, etc., to play the role of tap, branch, relay or conversion, providing great convenience for cable networking.

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.
