INTEGRAL GROUND MANHOLE STRUCTURE

摘要

PURPOSE: A manhole connected to ground is provided to maintain the ground performance for a long time by preventing corrosion or deterioration of a ground bar or ground terminal. CONSTITUTION: A manhole block(110) is combined with a manhole grounding block(120) to form an internal space of manhole. A pair of distributing lines(10) comprises a first distributing line(10a) and a second distributing line(10b). The first distribution line and the second distribution line are flowed in through a distribution line through hole to the internal space of the manhole block. A neutral line(12) is connected to each of the distributing lines. Each of the neutral lines is connected to a connecting point(13) of the neutral line. The neutral line grounds each of the contributing lines through a ground lead line(14).
