Newly Designed NXPRW-12/200-12.5 is used on 12kV outdoor overhead distribution system and overflow and short curt protection fo

Advantages of the Newly Designed Fuse: 

      The Newly Designed Fuse is designed and produced by our company and has passed overall trial report by National High-voltage Electric Equipment Quality Supervision and Inspection Center according to current national standard GB/T15166.3-2008.

      Newly Designed NXPRW—12/200—12.5 is convenient to electric maintenance, improves stability of electric power supply and is widely used and popularized in power system.

      Newly Designed NXPRW—12/200—12.5 is used on 12kV outdoor overhead distribution system and overflow and short curt  protection for line or transformers.

Product Characteristics:

High-voltage conducted end uses water-proof and dust prevention design and is suitable to  sand areas and improves product life.Arc extinguish uses knuckle style, arc extinguish performance is stable and has long life.Conducting contactor uses silver plating manufacturing techniques which increases conducting performance.Insulated porcelain uses solid stick structure, increases product mechanical strength and outside insulation meets requirement of heavy pollution and high altitude areas.Porcelain is linked to metal, uses imported sulfur cement(insulated cement). This kind of cement is of good shrink performance and suitable to various environment.NXPRW—12/200—12.5 uses water-proof and UV-proof steel-melted tube which increases product arc extinguish ability.Our design uses one-way downshift exhaust which can prevent water flowing and avoid influence of free air on upper line.Breaking current is 8kA which is the highest braking value domestically and equals to global similar products of ABB,SC,DN.The replacement of fuse wire is easy ,increases efficiency and reduces working power
