FIELD: building structures, particularly crossing piles for 110 kV power transmission lines adapted to provide passage from overhead transmission line into underground cable one. ^ SUBSTANCE: crossing pile comprises lower trapezoid section installed on foundation and upper section connected to lower one. Crossing pole also has ground cable peak. Secured to upper section are aligned cross-bars arranged in several layers. Power line wire lead is formed in each cross-bar. Beam carrying cable sleeve and excess-voltage suppressor is secured to each cross-bar. Cable lead-in is connected to pole members. Upper layer consists of linear cross-bars provided with power line wire leads formed at ends thereof. Number of aligned cross-bars is defined by total number of power line wires. Lower layer includes cable cross-bars. Each cross-bar supports beam carrying cable sleeve and excess-voltage suppressor. Power line wire lead-in members of linear and aligned cross-bars, as well as beams connected to aligned and cable cross-bars are correspondingly arranged in staggered order. Holders for cable position fixation in turning areas and fixing members to secure cable at pole faces are installed in cable lead-in direction. ^ EFFECT: possibility of cable leading out to any pole face, possibility of optimal cable installation regardless of consumer location, increased cable montage quality and extended span between the poles. ^ 5 cl, 7 dwg |
