Cross Arm Used in Transmission Lines

I believe you’re discussing the spacers in such as twin feeder kind transmission lines.

The impedance of a transmission line is dependent on a range of variables, but one is that the spacing between the ACSR Conductors. So to maintain the impedance exactly the same over the line spacers are added to maintain the correct spacing.

Impedance, energy factor, corona discharge and weight reduction effects are enhanced by spacing quite a few conductors apart to make a bigger effective single bulb.

We supply Transmission cross arm, Clevis Socket with high quality and factory price, and they are widely used in many applications.
