1. Practical DC reference voltage is higher than the national standard value of more than 4%, is conducive to improving the stability of the arrester.
2.High tolerance of energy tolerance, such as 10KV distribution type arrester 2mA square wave flow capacity of up to 150A; 4 / 10μs high current impulse withstand capacity of 65KA.
3. Leakage current is small, 0.75 times the DC 1mA voltage leakage current is usually not more than 20μA, and anti-aging performance, long-term use of stable and reliable.
4. Sealed structure is advanced and reliable, composite jacket to take a one - time overall molding.
5. Products creepage distance, good stain resistance.
6. According to user requirements for the design and production of various types of special requirements of the product.

Types of
    Drop arrester
    
I. Overview
    Drop type (castable, detachable) arrester is the distribution of zinc oxide arrester modified after cleverly installed in the drop-type fuse drop mechanism, to achieve in the case of uninterruptible power, The rods are easy to detect, repair and replace the arrester, not only ensure the smooth flow of the line, but also greatly reduce the power maintenance staff work intensity and time, especially suitable for substandard areas such as communications, airports, stations, hospitals, Business district and so on. Other performance with the distribution of lightning arrester.
    Drop arrester increased the disconnector, arrester in the event of an abnormal failure, the use of frequency short-circuit current let the disengagement device, so that the disengagement of the ground terminal automatically disengaged, arrester components fall, exit operation to prevent accidents to expand and easy to maintain ^ Members found in time to maintain and replace. Its fall principle similar to the fuse, fuse blows caused by melting pipe collapse. I used the company's current international most advanced thermal detonator, with fast action, a wide range of action current, but also tolerate the provisions of the current impact and the advantages of action load.
    Second, the installation instructions
    1, before installation, please check the arrester components and drop the degree of tension between the institutions to ensure good contact and devote the flexibility.
    2, drop-type body on the terminal connected to high-voltage lines, the lower terminal must be reliable grounding, do not reverse. 3, arrester put into operation before and after the operation of the note with the power distribution arrester. 4, when the arrester needs to be repaired or replaced, in the case of uninterruptible power, with the help of the insulation gate lock bar on the lightning arrester unit to facilitate the operation, as the replacement of the fall tube.
