Mine rubber cable cable cross section verification

(1) Select cables by voltage: Select according to the * in the general principles above.
(2) Select the cable cross section according to the economic current density: the calculation method is the same as the calculation method of the wire cross section.
(3) According to the line zui long-term load current verification cable section Iux≥Izmax
Where: Iux - the allowable load current of the cable (A);
Izmax - the large load current (A) of the long-term passing of the cable.
In our usual work, the long-term use of this method is the selection method. Usually, the working current of the line is first obtained, and then the working current according to the line zui should not be larger than the allowable current carrying capacity of the cable.
Uniform cable safe current carrying capacity (A)
We often encounter this situation in actual work. Due to the increase of load, the load current increases, the original cable current carrying capacity is insufficient, and the overcurrent operation. In order to increase the capacity, the cable is re-applied in consideration of the normal operation of the original cable. Construction is difficult and uneconomical. We often use double or even triple.
In the choice of the combined cable, many people think that as long as the cable cross section is satisfied, the smaller the cable cross section, the more economical and reasonable, is it actually the case?

Full-automatic Video Measuring Machine

The Full-automatic Video Measuring Machine is an artificial intelligence modern optical non-contact measurement instrument developed based on the digital image measurement instrument (also known as CNC image instrument). The full-automatic video measuring machine inherits the excellent motion accuracy and motion control performance of digital instruments, integrates the design flexibility of machine software, and belongs to the forefront of optical size detection equipment today.

The full-automatic video measuring machine is based on the CCD digital image, relying on the computer screen measurement technology and the powerful software capability of spatial geometry operation. After installing specialized control and graphic measurement software, the computer becomes the measurement brain with the soul of the software and is the main body of the entire device. It can quickly read the displacement value of the optical ruler and obtain the desired result instantly through software module operations based on spatial geometry; And generate graphics on the screen for the operator to compare the images and images, to visually distinguish possible deviations in the measurement results. All of this is done in real-time in front of powerful computer computing power, and the operator himself cannot detect it. This kind of precision instrument that can use CCD digital image, through computer software operation, to meet the needs of complex measurement is the real image measuring instrument.
