Product advantages
1. Surge Arrester Discharge Counter focuses on counting the number of lightning strikes, and the mechanical pointer remains stable without jumping; JCQ integrated leakage current monitoring, pointer+digital dual display, intuitively judges the insulation status of lightning arrester, and can grasp operational data without disassembling the machine.
2. The shell is made of high-strength insulation material, fully sealed waterproof and dustproof design, resistant to ultraviolet rays, high and low temperatures, suitable for harsh outdoor environments such as rain, snow, sand, coastal salt spray, etc., and can operate for a long time without water ingress or failure.
3. The base is reserved with standard installation holes, which can be directly fixed to the grounding terminal of the lightning arrester without additional modification; Suitable for the full range of 3kV-220kV zinc oxide lightning arresters, compatible with both new and old lines.
4. There are no vulnerable parts inside, and there is no need for regular calibration or battery replacement. The mechanical structure is stable and reliable, with a service life of over 10 years, reducing operation and maintenance costs.

Frequently Asked Questions
1. How to choose JS-8 and JCQ?
Just need to count the number of lightning strikes and choose JS-8 (cost-effective); JCQ (with more comprehensive functions) should be selected to simultaneously monitor leakage current and determine the health status of lightning arresters.
2. Is the product suitable for overseas markets?
Surge Arrester Discharge Counter complies with international common power standards and is suitable for 3kV-220kV distribution systems in Southeast Asia, the Middle East, Africa, Latin America, and other regions. It supports providing export certification materials.
3. What should be noted during installation?
When installing, remember to ensure reliable grounding, and connect the counter in series with the grounding terminal of the lightning arrester; It is recommended to do a good job of waterproof sealing for outdoor installation to extend the service life.
