Walk the route first
Record every pole position and measure the longest gap. Do not calculate from an average. Corners, road crossings and missing poles are usually where the route changes.
- Measure the longest clear span
- Note road and river crossings
- Record sharp direction changes
- Allow for vegetation and future growth
Match the hardware
The clamp, preform and bracket must suit the cable diameter and load. Mixing a higher rated cable with light fittings only moves the weak point to the pole hardware.
For uncertain routes, send the pole schedule or clear photographs to the technical desk before ordering.
