TRANSITION TOWER FOR AN OVERHEAD ELECTRICAL TRANSMISSION LINE INTO A POWER CABLE, AND OVERHEAD ELECTRICAL TRANSMISSION LINE HAVING SUCH A TOWER

This utility model relates to electrical transmission lines and can be used for arranging a transition between a high-voltage overhead line and an underground power cable. The technical result of the utility model consists in increasing the technological effectiveness of the installation and convenience in use of equipment for transitioning between an overhead line and a power cable. The tower comprises a post consisting of three joined sections (1, 2, 3). Crosspieces (4, 5, 6) in three tiers are fixed to the two upper sections (2, 3) of the post for suspending linear conductors with the aid of tensioning insulator suspension means (strings), which are not shown in figure 1. The crosspieces (5, 6) are fixed to the upper section (3), while the crosspiece (4) is fixed to the section (2) which is joined to the section (3). The sections (1, 2, 3) and crosspieces (4, 5, 6) are polygonal and in the form of truncated pyramids consisting of sheet steel. A platform (8) is fixed horizontally to the lower section (1) of the post for mounting the terminal cable equipment: terminal cable bushings (9) and surge arresters (10). The tower post can be mounted on an additional section, namely a stand (11). The crosspieces (5) of the central tier are fixed along one axis, while the crosspieces (6) and (4) are rotated towards one another about the post. Furthermore, the directions of rotation of the crosspieces (4) and the crosspieces (6), which are arranged on one side of the post, are in opposition to one another, while the angle of rotation of each crosspiece is a quarter of a right angle. Le modèle utile de la présente invention se rapporte aux lignes de transmission électrique, et peut être utilisé afin de réaliser la transition d'une ligne aérienne haute tension vers une ligne câblée enterrée. Le résultat technique consiste en une amélioration de l'aptitude au montage et de la commodité d'exploitation de l'équipement de transition de la ligne aérienne vers la ligne câblée. Le pylône comprend un montant se composant de trois sections assemblées (1, 2, 3). Sur les deux sections supérieures (2, 3) du montant sont fixées de traverses (4, 5, 6) en trois étages afin de suspendre les conducteurs de la ligne à l'aide de suspentes isolantes tendues (guirlandes) (non représentées dans la figure 1). Les traverses (5, 6) sont fixées sur la section supérieure (3), tandis que la traverse (4) est fixée sur la section (2) reliée à la section (3). Les sections (1, 2, 3) et les traverses
