It consists of overhead lines, cables, towers, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities, and plays an important role in distributing electric energy in the power grid. Under the influence of various external factors such as breeze vibration of conductors and wake-induced vibration, the lines are prone to cause adjacent phase conductors to touch each other and air insulation breakdown between lines. The most effective way to solve this contradiction is to install insulating spacers between adjacent phase conductors to ensure sufficient insulation distance between adjacent phase conductors.
