Barrel mast

from Wikipedia, the free encyclopedia

A barrel mast is a design of masts for electrical overhead lines .

A barrel mast is characterized by the fact that it has three cross members , of which the middle one has the largest span. This leads to a barrel-shaped profile of the pipe. The spans of the upper and lower traverse are often the same; However, the lower one can also be wider than the upper one, in order to leave the conductors with sufficient distance from the mast body, which widens downwards. Compared to Danube masts, barrel masts have a narrow route width, but are higher.

Barrel masts are not often found in Germany because the Danube mast is preferred here . In other countries, barrel masts are common, for example in the National Grid , Great Britain's extra-high voltage network, it is the standard design.

A special form is a barrel mast with circuits in a one-level arrangement , whereby the conductors of a circuit are attached in one level. Such barrel masts then carry up to six three-phase circuits on their three trusses.
