Not A Conductor By Itself Laser Pointer
In these entanglements. A kite with a wire skeleton is the most threatening. It may cause a short circuit directly. Affects the safe and stable operation of the line. Although some entanglement is not a conductor itself, it is susceptible to moisture and conductivity; it will still cause the line to trip. Affects the stable operation of the power grid. In extreme cases, even a large-scale blackout laser pointer can be triggered.

Statistics display. In recent years, the biggest threat to the safe operation of transmission lines has come from external damage. Nearly two-thirds of them were damaged by foreign objects similar to kites. In 2017 alone, the city cleared 52 easy-to-float hanging lines such as kite lines. The laser pointer is aimed at the pink balloon hanging on the line. "Tower Climbing Clearance" was upgraded to a laser obstacle clearance instrument. In order to clear obstacles, in the past, operation and maintenance personnel had to put on electric field shielding suits and climbed up tens of meters of power transmission towers to clean them up; they had to cut off power in rainy weather. When an obstacle is wrapped around the center of the sag of the high-voltage line. You must also "grind" back and forth with the aid of a tool such as a pulley. Not to mention the slow efficiency, there are certain risks.
Ensuring as much stability as possible especially involves eliminating interference from pressure changes, vibrations from acoustic and seismic waves, and even temperature fluctuations. The final task is to minimize the thermal motion of the atoms in the resonator, which is the Brownian motion that occurs in all materials at a finite temperature: for this purpose, the resonator is made of monocrystalline silicon and cooled to a temperature of -150°C .
