Cross arm electrical pole is used on low-voltage and 10 kV power lines to support insulators, conductors, and pole hardware. It is normally hot-dip galvanized according to outdoor utility requirements. The advantage is that the angle size, length, hole distance, and pole hardware position are made before galvanizing, which gives the installer a finished cross arm without drilling bare steel on the pole site.

Product Advantages
1) Cross arm electrical pole is produced after hole layout is confirmed, so insulator and brace positions match the utility drawing.
2) Hot-dip galvanizing is applied after cutting and drilling, which reduces exposed steel at hole edges.
3) Different line levels can use different angle sizes, such as L50×5 for 0.4 kV and L63×6 or L75×6 for 10 kV lines.
Main Applications
Used for low-voltage distribution lines, 10 kV overhead lines, pole mounted hardware, and cable support arms.
Suitable for new pole line work and replacement of old galvanized cross arms.
Production Process
Angle steel is cut to length, drilled or punched, deburred, hot-dip galvanized, and bundled by specification.
If the drawing has brace holes, the brace hole distance is checked together with the main line hole layout.
