Transcript of SIMpull Cable Pull Calculator 3 6
Use of Calculated Pulling Tensions
Calculations should be made to indicate whether the pull looks easy or impossible, making the decision to pull an obvious choice. When a marginal situation is encountered, the entire pull should be reviewed. This review may include more rigorous calculations or trial pulls. A final decision should be made based on installation factors known to the end user and installer. The sizes of the conduit are determined based on the calculations of the clearances, jamming, and fill. Pulling tensions may then be evaluated by determining the maximum tension based on the pulling device used and the maximum tension that can be applied to the conductors. The lesser of these two values is the maximum allowable tension (Tm). The pulling tension (T) required to pull the cable through the conduit is then calculated and compared to the maximum allowable tension. If the pulling tension exceeds the allowable tension or sidewall pressure, then conditions should be changed to ensure a successful pull.
How to enter a cable pull into the calculator. First, enter the wires going in the conduit. Next, enter the conduit type and size. Example: 3/C SIMpull CU THHN Size 350, with a 4/0 SIMpull THHN ground wire: in GRC (Galv Rigid Conduit) size 3''. It is assumed that it takes approx. 25 lbs of force to pull the wire off the reel. Thus, incoming tension is set at 25 lb and can be changed if needed. A cable pull is divided into segments. A segment is the length of straight section of the pipe and the details of the bend or elbow. IE. Segment 1 beginning of conduit to the end of the first bend. Segment 2 start of second straight section to the end of the second bend. Last segment will always be the straight section info and no bend section info. A segment has two parts that needs to be captured. The straight section and the bend section. The straight section consists of three elements: 1. The Angle (Slope) in degrees. Zero degrees (left blank)is horizontal. 90 degrees could be straight up or straight down, . 2. Wire is being pulled; Up, Down or HZTL (horizontal). 3. The segment length; is from the beginning of straight section to the end of bend. Example of the straight section: 90 degrees up for 14'. Enter as; Angle (Slope) = 90; Wire is being pulled = UP: Length ft. = 14. Note A horizontally straight section for 30' would be . Entered as; Angle (Slope) = (blank); Wire is being pulled = HZTL; Length ft. = 30. The bend section consists of four elements: 1. The bend type; the direction of the bend / elbow is turning? VCDN = Vertical concave turning down VCUP = Vertical concave turning up HZTL = Horizontal 2. Up, Down or N/A : how the wire enters the vertical part of the bend? Wire is going UP through the bend, Down through the bend, or N/A (horizontally). 3. The degree of the elbow or bend. 90 = 90 degree elbow 4. The radius of the elbow. STD = standard radius 18 = 18'' sweep radius,Bend is going down, the wire is going up to the bend, in a 90 degree elbow, with a standard radius.
Enter as: bend type = VCDN; Up, Down, N/A = UP; Angle = 90, Radius = std. This first segment will show Tension of 115 lb. and Sidewall Pressure of 74 lb.

Straight Line Drawing for calculating a cable pullPurple Areas = Input is mandatory for doing a cable pull calculation. What wire are you pulling into your raceway: number of wires, size and metal type, Insulation type, GW same info. (Example: 4/C 350 CU SIMpull THHN & 1 /C of 1/0 CU THHN GW) (Example: 1/C 350 CU 420 mil 35kV with a SIMpull PVC Jkt) What type and size of Raceway are you using. If using PVC indentify if it is schedule 40 or schedule 80. (Example: 3" Sch 40) If using Cable Tray you will need to know your radius (inches) of bend sections.
