Triangle frame Composite Insulation Crossarms developed by Shandong Taikai Electrical Insulation Co., Ltd. can be used as a tension crossarms and a corner crossarms. In order to reduce the scope of accidents caused by downed poles or broken wires, it is necessary to divide the straight line part of the line into several tensile sections. Since the line needs to have different angles of corners, a corner rod that balances multi-directional forces is needed.
Tension poles are also called load-bearing poles, which are poles that connect wires at both ends and need to withstand the tension from the wires. On the other hand, at the corner of the line, it bears the resultant force of the wire tension along the corner line direction. In order to balance the resultant force, it is necessary to increase the pull wire in the opposite direction.
The structure of the corner pole varies with the line angle. The maximum angle is 90 degrees. The overall angle pole is divided into two angle structures: below 45 degrees and above 45 degrees.Shandong Taikai Electrical Insulation Co., Ltd. produces Triangle frame Composite Insulation Crossarms, which can meet higher force requirements and enhance mechanical stability.
Triangle is recognized as the most stable structure, able to withstand large tension and wind loads. This reduces the vibration of the line, especially in high wind speed environments, which can effectively suppress line oscillation, reduce fatigue damage to the line, and extend the service life of the line.
