Product Details
Product overview
Composite jacket metal oxide arrester is a kind of advanced protection device to limit overvoltage. It is widely used in power generation, transmission, substation and distribution system to protect the insulation of electrical equipment from overvoltage damage.
Composite coat metal oxide arrester it not only has the advantages of porcelain metal oxide arrester, but also has good electrical insulation performance, high dielectric strength, anti-leakage, anti-corrosion, heat resistance, cold resistance, aging resistance; explosion-proof, hydrophobic, sealing and other advantages.
The drop type (drop type, removable type) lightning arrester is cleverly installed on the drop type mechanism of the drop type fuse after modification of the distribution type zinc oxide lightning arrester, so that under the condition of continuous power supply, the lightning arrester can be easily detected, repaired and replaced with the help of the insulating switch lever, which not only ensures the smooth flow of the line, but also greatly reduces the working intensity and time of the power maintenance personnel, it is especially suitable for places that are not suitable for power outages, such as communications, airports, stations, hospitals, and prosperous commercial areas. Other performance of the product is the same as that of the distribution type arrester.
