Product name	drop type fuse
Product model	HRW12-12KV/200A
Product set	3 PCS
Product description	HRW12-12KV/200A means that the maximum load current of the product is 200A, but the fuse current of the product depends on the fuse installed, and the fuse is how much A is how much A is fusing
Application	Drop-type fuse is the most commonly used short-circuit protection switch for 10KV distribution line branch lines and distribution transformers. It is widely used in 10KV distribution line and distribution transformer primary side as protection and equipment investment and cutting operation.

The lightning arrester is the basis for the insulation of all kinds of electrical equipment in the power system (transformers, reactors, capacitors, engines, motors, PT, CT, circuit breakers, contactors, etc.), and the protection performance of the lightning arrester determines the internal insulation indicators of all electrical equipment in the power system (short-time power frequency voltage resistance, lightning impulse voltage resistance and operating impulse voltage resistance, etc.).
Metal oxide arrester, commonly known as "zinc oxide arrester", is a product of conventional arrester. After the introduction of this technology in China since the mid-1980s, through years of practice, the current AC arrester performance of various professional arrester factories is comparable to the product gap in the United States, Japan, Western Europe and other countries, and the strength is comparable.
The working element of the modified product is made of multi-metal oxide powder based on zinc oxide, which has excellent nonlinear volt-amperity-characteristic, fast response to steep slope and large flow capacity. Products with gaps use self-blowing gaps. With voltage equalizing irradiation structure, the dispersion of discharge is reduced and the impact coefficient is small. The use of composite insulation jacket conforms to the trend of miniaturization, stabilization and maintenance-free of national standard power products. Compared with traditional inorganic materials such as ceramic and glass, polymer organic composite has the advantages of small size, light weight, anti-fouling and anti-cleaning, explosion-proof and shock-proof.
