Product Description

MEGATRO 110KV anchor portal overhead power line

Future termination tower of MEGATRO 110KV anchor portal overhead power line
A special kind of a dead-end tower is a termination pylon. Also called a terminal tower. It is used when the overhead power line terminates, and is connected to substation equipment, or transitions to underground cable. For voltages below 30 kV also pylon transformers are used.
Long spans

MEGATRO 110KV anchor portal overhead power line for crossings of large bodies of water, wide freeways, or valleys, where the span width of the conductors is very long, specific constructions must be used to achieve a wider distance between the conductors, mostly to prevent short-circuits which may occur when conductors come in contact with one another due to wind or other interferences. These towers may be built as H-frame towers, or may have each conductor placed on a single tower or mast. In every case, these towers are built more stably than most of the other towers used, as the wide span between towers means that much greater forces are placed on these towers.
Switch pylon
Anchor pylons may also have a switch attached to their crossbeam. These so-called switch pylons are operated from the ground by the use of long rods. The attachment of circuit breakers to pylons is only practical when voltages are less than 50 kV.
Sequences
This straight line is made of strain towers to achieve low profile of the pylons and high clearance of the wires.
Sequences of two or more strainer pylons are uncommon in a powerline because strainers require twice as many strain insulators as ordinary pylons. Longer wire sections thus reduce installation work and cost. Sequences of strainers are sometimes used at powerlines crossing valleys, or where the powerline runs a path
