MaxCell®
Pull-Test Information
Cable on Cable vs. Cable in Fabric Innerduct
Test Condition & Method
Pass Fail Criteria : Having no significant external damage on the cable sheath
Cable on Cable
- Minor abrasion at 250m but significant sheath damage at 500m and 750m
- Large amounts of PE flaking observed over longer distances
- Higher pulling tensions and longer pulls may lead to possible signal failure
Cable in Fabric Innerduct
- Very minor abrasion observed on the sheath
- Fabric Innerduct showed a small 75mm tear right where the cables crossed but the tear did not expose the cable to any significant damage Note: The cable was in a 10m continuous loop. Because of this loop the MaxCell saw the head of the cable pass over a minimum of 75 times during the experiment
- Higher pulling tensions and longer pulls possible without damage to the cable
Control: Cable Observation Before Test
Control: Cable Observation After Test
