10kV Zinc Oxide Arrester

The current capacity is increased to 100kA, and the damage rate of the arrester is greatly reduced (taking Hunan as an example, the annual damage rate is reduced from 19% to 0.3%). The burst probability of the arrester under high-amplitude lightning current is extremely low, and it can withstand multiple lightning strikes and can effectively protect Electrical equipment such as transformers and ring network cabinets.

Features of 10kV Zinc Oxide Arrester

  • A new structure integrating lightning arresters and insulators has been realized, and the product has the functions of insulation support and lightning protection.

  • Using large current ZnO resistors, the current performance is increased to 100kA.

  • By adopting large and small "flower arrangement" arrangements and increasing the creepage distance of sheds, the voltages of ice flash, rain flash, and pollution flash under D-level pollution conditions are increased by 30%, 50% and 27% respectively.

  • The product is light in weight, easy and convenient to install on site, and does not need special grounding treatment, and it only needs to meet the natural grounding requirements of the tower.

  • In case of failure and damage under special circumstances, the overall mechanical and insulation performance of the product will not be damaged, and immediate repair and replacement are not required, but there is no lightning protection function under operating conditions.
