Outline:

       The organic composite insulating drop-out fuses insulator is overall die formed by silicone rubber epoxy glass steel barafter smearing couple linking agent. Has the high strength, weight light, anti-pulls the anti-curved ability and so on merits, overcame the traditional porcelain insulator to fear fragile, not drastic changes in temperature since the burst of shortcomings.

Operating principle and structural feature:

       As shown in Figure, it is composed by insulating bracket conductive stent systems and fusion tube, the static contact at both ends of the insulating bracket, dynamic contact installed at both ends of the fuse.

        While operatingt, in the line of the series. Normal working hours, after the fuse tightens, let the cartridge fuse high and low activity joint lock, therefore the cartridge fuse can switch on the position in the static contacts pressure temporary lodging, when the system failure, the fault current causes the fuse to burn-out rapidly, and forms the electric arc. The cartridge fuse inside lining quenching of arc tube is decomposed the electric arc hot function the much gases, causes in the tube to form the high pressure, and intense vertical blows along the channeling, causes the electric arc to elongate rapidly. In the electric current zero hour, has extinguished as a result of the intense ionization. After fuse burn-out, high and low part of dynamic tension and lost contact over the next so that the lock-release, the fuse of contact in the stretch and fuse under its own weight of the rotating drop, a highly visible isolation space.

Applicable scope:    

 1. Products basic conditions:

         1) Altitude: general-not more than 3,000 meters

         2) the ambient temperature is not higher than 40 , and not lower than -40

2. Products does not apply to the following places:

         1) a fire or explosion of dangerous places.

         2) a severe shock or impact sites.

         3) Conducting the role of chemical gas and serious dirt, salt spray areas.
