Our plant will be connecting to the local electrical utility via two feeders of 33kV. Each feeder will be rated at 700Amps. The distance between the utility and our plant is 5500 metres. These cables will be installed in a common power corridor. We have selected to use 2*630sqmm single cores per phase. We have estimated that we will need approximately 96 joints. We believe that these joints should be installed in a concrete chamber to allow for the possible failure, testing and quick repair.
Is there a IEEE or IEC specification or good engineering practise that would advise what to do for such a high number of joints?

Current integrated circuit (IC) designs are complex, which can result in different voltages being located close to one another. To prevent time dependent dielectric breakdown (TTDB), it is essential to incorporate space rules within IC design. Download Now
