What does 7×19 wire rope mean?
A 7×19 aircraft cable is made from 7 strands that each include 19 wires, for a total of 133 wires. This means a 7×19 construction consists of over 2.5 times the total number of wires as a 7×7. The difference in wire count imparts different properties to the finished cable.
What is the difference between 1×19 and 7×19 cable?
1×19: used when engineers need freedom when designing a stiffer cable that does not bend or flex. This rope is commonly used when running ropes in a straight line, like for guy wires. 7×19: heavy applications call for these ropes. They can handle a lot of stress before breaking.
