Product details

220kV transmission line 

Electric transmission line power steel poles are made of polygonal steel pipes, circular steel pipes and other steels. Hot dip galvanizing or hot spraying zinc (and zinc alloy) coating is used for anticorrosion treatment. It is mainly used for power line erection. It's a substitute for traditional cement poles.

Advantages of 220kV transmission line

1. The electric power steel bar occupies a small area.

2. The appearance of the steel bar is beautiful.

3. Steel bar construction is simple and quick.

4. The material of steel bar is not easy to be stolen.

Apart from the above points, the electric steel pole has the advantages of short production cycle and great stress.

The advantage of 220kV transmission line Steel Power Pole

1.Steel Power Pole Lifespan of between 10 – 15 years depending on installation conditions.

2.Galvanized steel poles are without a doubt more attractive and less obtrusive, they can be painted before installation to match the colour scheme of an existing or new home and are extremely strong.

3.Steel poles are generally cheaper to install and can be erected in tight spaces without the aid of heavy lifting equipment.

4.Steel poles are completely termite proof, in areas prone to termite damage you can rest assured that your timber pole is not on the menu for those destructive little critters.
