CONDUCTOR ARRANGEMENT ON THE TOWER

Tower head types

On towers it is possible to have virtually any arrangement of conductors i.e. any tower head type.

Types used for non insulated conductors are:

  • Symmetrical heads formed by two sided cross-arms
    • G – gama
    • D – delta
    • T – trapez [trapezium]
    • B, BU – bačva [barrel] (B without, and BU with the earth wire)
    Symmetrical heads formed by two sided cross-arms
  • Asymmetrical heads formed by one sided cross-arms
    • J, JU – jela [fir] (J without, and JU with the earth wire)
Asymmetrical heads formed by one sided cross-arms

Cross-arms are mounted on the upper section of the tower with the possibility of connection on every 0.85 m of the section, where necessary. For the central conductor of the head D and for the earth wire on heads BU and JU, the top frame structure is mounted at the top of the tower, hereinafter named only as – top.

Besides cross-arms for types of tower heads, it is also possible to attach on towers suspension equipment and structures (frames, cross-arms, etc.) customised for suspending insulated conductors, cables, devices, etc.
