# Angle to the plane of a section

For a horizontal plane, the angle is zero.

For an upward slope (positive elevation), the angle is positive. For an angle of 90°, the pulling is straight up.

For a downward slope (negative elevation), the angle is negative. For an angle of -90°, the pulling is straight down.

The installation of HV cables in vertical shafts is very dangerous. You must be fully aware of the risks involved and the installation must be handled by professionals. The Cableizer cable pulling module cannot be used to determine if it’s safe or not.
