1 . The actual DC reference voltage is more than 4% higher than the national standard value, which is beneficial for improving the stability of the lightning arrester.
2 . The energy tolerance margin is large, for example, the 2mA square wave current capacity of 10KV distribution lightning arrester can actually reach 150A; 4/10 μ s high current surge withstand capability reaches 65KA.
3 . The leakage current is small, usually not exceeding 20 μ A at 0.75 times the DC 1mA voltage, and it has good aging resistance and stable and reliable long-term use.
4 . The sealing structure is advanced and reliable, and the composite jacket is formed by one-time integral molding.
5 . The product has a long creepage distance and good stain resistance.
6 . We can design and produce various products with special requirements according to user requirements.

type
Drop type lightning arrester

1、 Overview
Drop type (throwable, detachable) lightning arrester is a distribution type zinc oxide lightning arrester that is ingeniously installed on the drop type mechanism of a drop type fuse after modification. It can be easily inspected, repaired, and replaced with the help of an insulated switch control rod under continuous power supply, ensuring the smooth operation of the line and greatly reducing the workload and time of power maintenance personnel. It is particularly suitable for places where power outages are not advisable, such as communication, airports, stations, hospitals, bustling commercial areas, etc. The other performance of the product is the same as that of the distribution type lightning arrester.
The drop type lightning arrester has added a disconnector. In the event of an abnormal fault in the arrester, the disconnector is activated by the power frequency short-circuit current, causing the grounding terminal of the disconnector to automatically disconnect. The arrester components flip over and exit operation to prevent accidents from escalating, and it is easy for maintenance personnel to promptly detect and replace them. Its flipping principle is similar to a fuse, where the melting of the fuse causes the melting tube to flip over. Our company has adopted the most advanced thermal explosive release device in the world, which has the advantages of fast action speed, wide action current range, and the ability to withstand specified current surges and action loads.
2、 Installation and usage instructions
1. Before installation and use, please check the tightness between the lightning arrester components and the drop mechanism to ensure good contact and flexible loading and unloading.
2. The upper terminal of the drop mechanism is connected to the high-voltage line, and the lower terminal must be reliably grounded and not connected in reverse. 3. The precautions for lightning arresters before and after operation are the same as those for distribution type lightning arresters. 4. When the lightning arrester needs maintenance or replacement, it can be easily operated by aligning the insulation switch control rod with the hook on the lightning arrester unit without power supply, just like replacing a drop type melting tube.
