Outline:

   The outdoors high voltage fuse applies to 10kV, 48Hz-62Hz exchange electrical power system, makes the transmission line and power transformers short circuit protection and the over current protection.

Product performance characteristic:

This product is one kind of a roof sealed, anti-wind and snow, and strong anti-filthy, inline structure of the two-point transmission interrupter protection device. The fuse insulator is overall die formed with new material after smearing couple linking agent on the frame. 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.

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.

Operating principle and structural feature:

   The fuse is composed by the insulator, the high and low antifouling cover, the high and low electronic contact dot, the extinguishing of arc tube, the extinguishing of arc tube uses the interpolation formula, 360° the revolving installment (overcomes the shortcoming with installment and using inconvenient as similar products) the two point extinguishing of arc. When fuse is burning-out, the placement of the hanging can be rapidly interrupt, instantaneous opens breaks, forms the obvious separating instruction
