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.
