Charging characteristics of the special power supply arrester for charging piles

In recent years, with new energy and our lives getting closer and closer, new energy vehicles have also developed greatly, which requires a large number of charging needs. However, most of the charging piles are outdoors and are vulnerable to induced lightning surges. When subjected to a lightning strike, the electronic system and communication system of the charging pile can be easily damaged, which will result in the vehicle not being able to charge, or the vehicle being charged. This may have serious consequences, and the cost of post-maintenance is also considerable.


According to the provisions of GB50057 and GB50343, for special equipment that needs protection, the rated value of impact voltage (UW) should not exceed 1.5 kV. The corresponding power SPDs belong to Class C power protection with a current rating of 20kA to 40kA and a maximum continuous operating voltage of AC385V. For the protection of the charging pile, a professional charging pile power supply lightning protector can be used. This kind of lightning protection device generally has the following characteristics:

1. The critical control point of this type of lightning arrester is that the voltage protection level (Up) should be less than the UW design;

Second, the use of high-performance MOV, with high reliability;

Third, with work failure indication, optional remote alarm function;

Fourth, and the use of temperature control protection circuit, built-in thermal protection, automatic short-circuit failure device;

Fifth, the use of standard modular design, easy installation and easy maintenance. Can effectively protect the charging pile from lightning strikes.


Looking at the trend of automobile development, more and more electric vehicles will be used in the future. Charging piles will also develop along with it. Charging piles are an essential part of electric vehicles and cannot be neglected in safety maintenance. It is necessary to plan the installation of lightning protection facilities. In order to reduce the trouble of future maintenance, it is better to install special lightning protection devices for the charging piles to prevent losses caused by lightning strikes.

Seal Repair kit

Cypher SPRSEALS - it starts with seals

Since 1998, in the field of mechanical seal work and control, we have made step-by-step efforts to overcome the limitations and difficulties of the factors that affect the stability of the sealing performance, such as the material and the shape of the sealing lip.
Since 2000, continuous improvement and optimization of polyurethane elastomer materials and research on mixing with different materials and chemical raw materials. While the physical properties are balanced, new material performances after different chemical mixtures are also deeply developed.

Regarding the mixing research and development of nitrile rubber, hydrogenated nitrile rubber, silicone rubber, fluorinated rubber and various metal powders, countless deployment tests have also successfully realized the ideal special sealing material.
In the development and improvement of polyamide (nylon resin), polytetrafluoroethylene, and phenolic resin, we also ushered in a rapid increase in the number of our European customers and a doubled increase in sales in the Asian market.

We are researching dust seals (DKBI), piston rod seals (IDI, IUH, HBY), support rings (KZT,), piston seals (OUH, SPGO) in conventional hydraulic sealing systems day after day ), anti-wear rings/anti-wear rings (WR, SPGW) and are suitable for all kinds of jib cylinders, cantilever cylinders, bucket cylinders, lifting cylinders, and power steering cylinders.
Including the research and development and iterative production of the sealing ring of the hydraulic breaker, there have also been more new breakthroughs.

Thank you very much for your attention. If you have any demand for sealing system solutions, please be sure to contact me. I will cooperate with you in an honest and professional manner.
