Sulphur hexafluoride (SF6) is a good gas insulator. Its typical application is gas insulation in high-voltage switchgear of power supply systems. When the sulphur hexafluoride gas encounters high heat and high temperatures(e.g. arc), it produces hydrogen fluoride and sulphur dioxide gases, which coexist with undecomposed sulphur hexafluoride gases. The rated pressure of the SF6 high voltage circuit breaker is usually 0. 0.6 MPa(table pressure). The pressure of the SF6 gas must be checked against the temperature curve of the product when inflating or checking the temperature curve. FLN36-12kV SF6 load break switch is a switch equipment for medium voltage switchgear, using SF6 gas as arc extinguishing and insulating medium. There are three working positions: open, closed, earth position in the switch. The compact size, easy installation, and fine adaptability to environment make the switch suitable for many different applications.

Newly developed load break switch, applied on SF6 RMU. With features of high efficiency, safety, reliability, simple structure, flexible operation, interlock reliable, easy to install and so on. It satisfies with standard IEC94, GB3804, GB16926 and so on. The FL(R)N36 Indoor AC High Voltage SF6 Load Break Switch and LBS-Fuse Combination are designed for use in three-phase AC 50/60Hz RMUs (Ring Main Units) and terminal power stations. These switches are suitable for protecting power systems operating at 10kV, 24kV, and 35kV under on-load conditions. They are capable of interrupting on-load current, closed-loop current, no-load transformer capacity, and cable charging current. When equipped with a fuse combination, they can cut off any current within the range of the rated short-circuit breaking current. These devices find application in RMUs and combined transformers, among others.
