The main power line to the distribution box cannot be pulled
Be sure that the power distribution box has sufficient power provided to it. Long cable runs can result in a voltage drop, which can be solved by using a heavy gauge wire. High Maintenance Difficulty: This is mainly due to the wide area covered by power transmission and distribution lines, the harsh terrain of the laying areas, and the impact of seasonal climate changes, all of which contribute to difficult maintenance. Check wires/DIN terminal clasps to. Line repair and maintenance are essential for ensuring an uninterrupted supply of power. Maintenance is primarily performed every year, once before monsoon & again after monsoon, to determine whether any breakdowns have happened in the line. Some of the operations performed during maintenance. Touching a power line is not necessary for danger; electricity can bypass wood, plastic or rubber, if it is damp or dirty, and cause fatal shocks. Don't rely on gloves or rubber boots to protect you. There is a trend toward larger conductors, higher voltages, longer spans and greater ground clearances.
