Poles for transmission lines

The treansmission lines with their masts are the conductors of the electrical power supply. The masts are mainly manufactured in wood, concrete or steel construction and can have various designs. For the high and extra-high voltage network (220kV and 380kV), steel lattice masts are generally used to allow for great heights and spans. The individual bars of these lattice masts are mainly made of hot-rolled angle steel, which can be easily transported and installed. The connections are mostly used as
