Calculation Method of Corrugated Cable Spool Length

2022-10-26

For the calculation of the length of wire and cable wound on the reel, in our cable industry, there has never been a universal calculation method. Now let's introduce the calculation method of wire reel.

Common calculation methods include:

1 Volume calculation method.

2 Integral calculation method.

3 Layered calculation method.

These methods are not absolutely accurate or inaccurate, and there will always be some deviation in the actual process of wire take-up. The main reasons for the deviation are: 1: the outer diameter of the cable is not the ideal circle, 2: the tightness of the flat cable, 3: jumper may occur in the process of the flat cable, 4: the space gap between the flat cable and the end face of the side plate is uneven, etc.

Since each theoretical calculation method may be different from the actual take-up length, I choose a theoretical calculation method, combined with the data obtained in the past, so as to minimize the error value.

1 In the above calculation methods, choose a relatively simple method: volume calculation method.

Volume calculation method. Its theoretical basis is: the length of the wound cable=the usable volume of the reel/the sectional area of the cable * the empirical coefficient.


2 Refer to the empirical value of actual take-up length of previous wire and cable plants. The following table is the data sheet summarized in practice. Because all the records are usually for delivery wire reel, there are some differences between the reel size and the standard reel size, so there are also some differences in the assembly line length.

The above methods are just my personal opinions on wire reel calculation. If you have better methods or suggestions, please contact the ONEREEL team for discussion and mutual progress.
