Tall Building Electrical Lightning Ground Rod , Roof Lightning Arrester Rod

Product Specification

Home grounding wire lightning rod, high-rise building discharge rod, household roof lightning protection.

Working principle of product

   In the thunderstorm, the lightning rod and the top of the tall building are induced by a large amount of charge when there is a charged cloud over a high building. Because the needle of the lightning rod is sharp, the most charge is always gathered at the tip of the conductor when the electrostatic induction is induced. In this way, the lightning rod congregates most of the charge. The lightning rod also forms a capacitor with the charged clouds, which is relatively small because the two pole of the capacitor is small and the capacitance is very small, that is to say, it can hold very little charge. When it charges more clouds, the air between the lightning rod and the cloud layer can easily be breakdown and become conductor. In this way, the charged cloud layer and the lightning rod form the path, and the lightning rod is grounded, the lightning rod can import the charge on the cloud layer into the earth, so that it does not pose a danger to the high-rise building and ensures its safety.

Product features

Product specification

Brief introduction

   Lightning rod products are used to protect power plants, substations, electrical transmission lines, individual sections and industrial and civil high-rise buildings. The lightning rod is directly grounded, and the height of the needle is higher than the line. In the course of the lightning guide circuit extending to the ground, due to the influence of the lightning rod distorting the power plant, the lightning rod will gradually turn and hit the lightning rod, thus avoiding the development of the lightning first guiding the protected equipment. It is a rational equipment to prevent the direct lightning strike.

Use of attention

  1. we need to install the base of lightning rod in advance and install the base seat in advance.

  2. the connection between the flanges of the lightning rod and the top pedestal of the vertical pole is reliably welded.

  3. installation and testing of lightning rod should not be carried out in thunderstorm days.

  4. the value of grounding resistance should be in conformity with the national standard

  5. the lightning rod is selected according to the area and height of the protected building, the riot day of the mine and the correction coefficient of the geographical environment and the property of the building, and the height of the pole of the lightning rod is determined.

Company profile

   Thor has been designing new products to meet the RoHS directive since 2006. Thor’s ongoing commitment to RoHS compliance includes continuing efforts to reduce the presence of hazardous substances in the design and manufacture of a growing number of popular products.
   All types and classes of our lightning and surge arresters 20KA~200KA(8/20μS) and 15KA~50KA(10/350μS) are tested and pass all the requirements based on their class.
