Description

A concrete pole with an internal grounding channel and a lightning rod at the tip

technical field

The utility model relates to the technical field of concrete electric poles, in particular to a concrete electric pole with an internal grounding channel and a tip lightning rod.

Background technique

Concrete poles are poles made of concrete and steel bars or wires. The cross-section of the pole has square, octagonal, I-shaped, ring or other special-shaped cross-sections. The most commonly used is a circular cross-section. The length of the pole is generally 7-18 meters. There are both tapered poles and equal diameter poles. The most commonly used is a tapered rod. The tip diameter of the tapered rod is generally 190 or 230 mm, and the taper is 1:75.

Concrete poles are mostly cast by centrifugal method. The steel bars and concrete are firmly bonded. The two have the same temperature expansion coefficient, which will not cause temperature stress damage due to unequal expansion. When the pole is bent, the concrete is compressed. Rebar in tension.

When installing the above-mentioned concrete pole, a grounding body needs to be buried underneath, and the equipment on the pole is connected to the grounding body through a grounding wire. The grounding wire is fixed on the surface of the pole body by a rigid cable tie, which is easy to be corroded and damaged. When the staff works on the pole, if there is a ground wire on the surface of the pole body, it will hinder the staff. When high and low voltage grounding wires need to be hung in urban streets and some special areas, if the pole is surrounded by concrete structures or the soil is hard, the grounding rod will not be able to be inserted or the insertion length will be insufficient. The lightning protection measures for the above-mentioned concrete poles are to install lightning arresters, which will be broken down and cannot prevent lightning from directly hitting the line equipment.

In the prior art, there is no pole that allows the equipment that needs to be grounded on the pole to save the ground wire, allows the equipment to be connected to the ground through the inside of the pole body, and can be equipped with a lightning rod.
