Everyone knows that power fittings play a huge role in life. The quality of power fittings must be good enough to ensure that there will be no line faults during electrical transportation or use. If the performance parameters of the selected fittings cannot meet the conditions of use It is not acceptable, so what should be paid attention to when assembling power fittings?
The precautions for assembly of power fittings are as follows:
1. The strength should be matched with the extra-large use stress of the wire, especially the first fitting.
2. Pay attention to the match between the ball and the socket.
3. Pay attention to the direction holes and match with the cross arm members of the tower.
4. Pay attention to vertical, horizontal and longitudinal loads when selecting U-shaped bolts.
5. When choosing fittings, suspension clamps should focus on breaking strength, while tension resistance and splicing fittings should focus on grip strength.
6. It is not advisable to use upper pole suspension clamps for up and down hills and cross crossings.
7. The compensation length (L=b·sinθ/2) should be considered for the two hanging points.
8. Two different metal joints should consider the chemical influence, generally steel-aluminum joints are used.
