Can import staking table from a database and automatically string wire
Added support for NESC 2002 and Russian Electric Safety Code
Added File/Export/Web command that creates PDF (requires Adobe Acrobat Writer) representation of sheets along with HTML index page and assorted reports.
A new, streamlined version of PLS-CADD used to quickly model a few spans. Developed specifically for Joint-Use type applications, PLS-CADD/Lite is the ideal tool for quick sag-tension, clearance and loads calculations.
Input kept to minimum needed to model span yet still flexible
Span geometry entered using one or more of following:
X, Y and Z coordinates of attachment points
Span bearing, length and change in elevation
Span bearing, wind span and weight span
Wire tension determined from one of following inputs:
Tension
Catenary constant
Mid span sag
X, Y and Z of point on wire
Automatic sagging criteria (% of RTS)
Up to 60 wires fanning out in all directions
Sag-tension calculations
Structure loading calculations
Clearances between wires and crossing spans
Option to string wires to and develop loads for PLS-CADD, PLS-POLE and TOWER structures
The following screen shots show the new PLS-CADD Structure Clearances feature. This function calculates the minimum distance between
all wires and all structures in your line. The output can be graphical as shown below, in a report and/or in a spreadsheet.
It takes only a few minutes to determine the clearances for a hundred mile line (the time is cut in half for dual processor machines).
Here you can see the options available with this function and the results for one lattice tower. The minimum distance between the wires on
the left and the structure lies along the insulators since the conductors are swung away from the structure. On the right of the structure
you can see that the minimum separation can be controlled by several different parts of the structure: At the top, it
is limited by the distance to the lower hanger, in the middle it is limited by the distance to it's own arm and at the bottom the limit comes from
the distance to the tapered tower body. Note that this calculation includes the effects of dip angle as shown at the bottom right conductor.
Here you can see clearances checked to a guyed portal tower. The minimum clearance for the leftmost conductor is to the
top of the arm. The middle conductor back span is closest to the bridge and the ahead span is limited by the longitudinal guy!
The right conductor is closest to the latticed mast due to the swing towards the structure and actually violates the required
clearance of 7.5ft which is why it is drawn in red.
