FN18 load switches and load switch-fuse combinations are high-voltage, high-performance load switches combining compressed-air arc extinguishing and gas-produced arc extinguishing. The combination of load switch and fuse combines the advantages of the load switch with those of the fuse to switch any load current up to the rated breaking current of the load switch, and to switch any overcurrent up to the rated short-circuit breaking current of the combination by means of the operation of the fuse and its impinger. It is used in three-phase power distributions of AC 50Hz rated voltage 12kv and rated current 630A Esp For power ring network in city net work construction improvement high-rise buildings and public facilities as an ideal product to protect package substation and transformer It has the features of advanced design simple operation impact structure smart appearance light weight complete function fast on-and off speed and high reliability.

FN18-D is a general purpose, three-pole, load break switch that offers switchgear owners and assemblers the advantages of an advanced interrupting technology and proven, dependable performance in a compact design. The switch is available to switchgear assemblers as a building block for metal-enclosed and pad-mounted switchgear applications in ratings from 12-40.5 kV. The standard FN18 switch includes a heavy-duty steel frame with stand-off insulators, a unique puffer-type arc extinguishing system, an operating mechanism and current-carrying components, including blade-type interrupters with cast hinges and jaw connectors. Optional accessories and features include a variety of operating handles, a motor operator, auxiliary switches, a shunt trip device, fuse bases, mechanical fuse tripping, grounding switches, mechanical door interlocking and key interlocking. FN18 series indoor high-voltage load switch has the advantages of easy design, operation, compact structure, small volume, full function, light weight, fast breaking and closing speed and high reliability. It is suitable for AC 50Hz, rated voltage 12kV, 24kV, rated current 630A and three-phase distribution system, especially for city network construction and renovation projects, high-rise buildings, ring network power supply of public facilities, and is an ideal product for box-type substation and transformer protection.

FKN12-12D series air-blast Ioad break switch and FKRN12-12D series air-blast load break switch-fuse combination apparatus are new series switchgear applies to three-phase electric distribution system of rated 12kV, acting as protecting and control apparatus for transformers, cable and overhead wiring.

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.
