Feature comparison

For steel tube towers used along urban roads, composite cross arm insulators can effectively reduce the tower arm spacing and extension distance, reduce the tower height, and increase safety and storm resistance. Installation method A: The composite cross arm insulator is installed slightly upward, and the suspension clamp is directly suspended, which can minimize the swing range of the line and reduce the transmission space.

Composite suspension insulators are installed vertically. Because the wires are swayed by wind, a longer arm is required.

When composite suspension insulators are installed vertically, the distance between the upper and lower tower arms needs to be greater than the sum of the length of the suspension insulator and the safety distance, which increases the tower height and the stress on the tower. Installation method B: Cable-stayed composite suspension insulator can increase the bending resistance of the cross arm.
