Pole series - Power pole

Back

The composition of the power pole 1, the pole body: is the main component of the power pole, generally steel pipe or concrete precast components. The height and thickness of the rod body are determined according to the transmission voltage and load requirements, usually between 10 and 30 meters. 2, cross arm: connecting the power pole rod body and wire parts, responsible for bearing the weight of the wire and wind load. The main materials are steel pipe, steel plate, stainless steel and so on. 3, cross arm: mainly used to connect two or more power rods to form a stable triangular support structure. The material of the cross arm is usually steel pipe or steel plate. 4, anchor: used to fix the power pole, to prevent the power pole from being blown down by the wind or other external force. Anchors are usually divided into ground anchors, Angle iron and concrete foundations. 5, insulator: used to isolate the contact between the wire and the power pole, to prevent leakage. Insulator materials are usually porcelain, glass fiber and organic polymer.
