GIS (post, with insulation natural gas) posts that are in the network, the above distribution are used. In the post conventional because of issues dielectric (the insulation capitalism is the worst enemy) have a distance between the conductor, we put, and usually this works because it causes enlargement of the post is to the beauty of the city can damage and in terms of insulation also not very interesting. In the post, the GIS conductors are inside the tube are placed inside the pipes full of SF6 gas, which is a insulating so good. With this, the conductors are too close to me, straddle (distance between the phases in each kv only 25mm) and post very little more and more beautiful. and in terms of insulation and safety, also reliability more than forecast.
