Multiple Spike Lightning Rod Description:
Multiple Spike Lightning Rod includes a metal outer cover, a plurality of discharge rods are evenly spaced on the metal outer cover, a plurality of upper discharge electrodes are provided on the upper ends of the discharge rods, and a discharge tube is connected to the lower end of the metal outer cover. There is an insulating support in the discharge tube at the lower end of the metal cover. The upper end of the insulating support is connected to the discharge rod provided on the top of the metal cover. The lower end of the insulating support is connected to a lower discharge electrode. The outer wall of the lower discharge electrode is connected to the inner wall of the discharge tube. There is a discharge gap between them The lower end of the lower discharge electrode is supported and connected to the transition section through an insulating pad. The lower discharge electrode is connected to the earth through a ground wire. It has a reasonable structural design, does not require a power supply, and utilizes the thundercloud electric field to self-energize. Corona discharge and lightning drive are reliable and stable, have no negative impact on surrounding facilities, are easy to install, and have strong wind resistance

Multiple Spike Lightning Rod Advantage:
It has multiple gaps or arc extinguishing gaps, consisting of a main gap and many small gaps connected in series, a gap exposed to the atmosphere called the main gap and multiple gaps with multiple air chambers installed in an insulating rod made of special materials;
Low lightning protection level and large flow capacity can withstand direct lightning strikes; high arc extinguishing ability protects the safety of transmission lines;
Simple structure, small size and light weight; easy to install and maintenance-free during use; can be operated and used in harsh environ men ts without fear of pollution;
It has good insulation coordination with the protected equipment, strong arc extinguishing ability, and is unlikely to cause the circuit breaker to trip;
The discharge voltage is low and the dispersion is small, no clipping is generated during operation, and the protection performance is strong;
The valve plate is not easy to age. After running for a period of time, the valve plate potential is evenly distributed and the valve plate has good uniformity;
