Descriptions:
220kV 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.
Product Advantages :
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.
