China Double Circuit Catenary Pole Structure (MGP DCP007

DOUBLE CIRCUIT Catenary pole STRUCTURE Double circuit catenary pole structure refers to one single pole to carry double circuit transmission line, which has two circuits. Usually both circuits operate at the same voltage. This type poles are mainly used in city grid project, and widely used in oversea regions.

A disadvantage of double circuit transmission lines is that maintenance can be difficult, as either work in close proximity of high voltage or switch off of two circuits is required. In case of failure, both systems can be affected. The largest double circuit transmission line is the Kita Iwaki Powerline.

In order to prevent this, the portion of the pole below the ground level is impregnated with preservative compounds like creosote oil. Double pole structures of the ‘A’ or ‘H’ type are often used to obtain a higher transverse strength that could be economically provided by means of single poles. The main objections to wooden supports are :

Structures may be as simple as wood poles directly set in the earth, carrying one or more cross arm beams to support conductors, or "armless" construction with conductors supported on insulators attached to the side of the pole.

The figure shows RCC poles for the single and double circuit. The holes in the poles facilitate the climbing of poles and at the same time reduce the weight of line supports. The main difficulty with the use of these types of electric poles is the high cost of transport owing to their heavy weight.

For a single wood utility pole structure, a pole is placed in the ground, then three crossarms extend from this, either staggered or all to one side. The insulators are attached to the crossarms. For an "H" type wood pole structure, two poles are placed in the ground, then a crossbar is placed on top of these, extending to both sides.

Normally in d.c. systems with metal catenary support structure voltage limiting devices are used to connect the catenary support structure to the running rails. Main goal of these is to create a short circuit path in case of failure of an insulator, causing the substation to switch of, thus preventing that a catenary pole becomes a live part.
