            High Voltage Steel Power Pole Introduction

            Electric 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 of [1]. It's a substitute for traditional cement poles.

            The technological process of high voltage steel power pole:

            1. Steel processing and reinforcement cage production: steel cold drawing, cutting, bending and binding.

            2. Concrete batching and mixing system: concrete batching and mixing.

            3. Wire rod forming: Centrifugal hair forming round pole (need centrifuge, mold and distributor and other equipment), or shaking other types of pole (need distributor, shaking table, mold and other equipment)

            4. Steam Maintenance: New type pole with touch and stop for a period of time, into the steam maintenance room, maintenance for a few hours

            5. Demoulding and Maintenance: The pole with a mold out of the maintenance room, demoulding, demoulding pole continue to maintain moisture or soak for a period of time.

            Installation way

            The transmission poles below 20 meters are mostly directly buried,?

            more than 20 meters, directly buried with flange installation.?

            85ft above flange installation.

            Classification of electric poles

            There are six types of poles used in overhead lines: linear pole (intermediate pole), angle pole, tension pole (sectional pole), terminal pole, crossing pole and branch pole. Generally, a complete overhead line has a turning angle and a span. Therefore, when choosing the pole type, we should consider the following aspects:

            1., we must consider safety and reliability. Righteousness can not affect the movement of vehicles or ships, but also consider saving materials.

            2. The pole type should also be selected according to the distance between the transmission line, the sag of the conductor, the minimum vertical distance between the conductor and the ground and various facilities, and the installation position of the crossbar.

            Choose the rod type according to the location of the installation site. The straight bar is the support point of the straight line part of the overhead line, the tension bar is the support point of the sectional structure, the corner bar is used to change the direction of the support point, the terminal bar is the support point of the beginning or the end, the branch bar is used to divide the support point of the branch line, and the span bar is used to cross a certain place.
