Installation procedure for hv cables. Prior to start the installation of high voltage cables refer to the approved shop drawings related to the area of installation and ensure that required materials are available at site as per approved material submittals. Power cables with extruded insulation and their accessories for rated voltages from 1 kv um 1 2 kv up to 30 kv um 36 kv part 1. Cables should not be installed at ambient temperatures.

This means that they have a full rated insulation system which will consist of insulation semi con layers and a metallic shield. Design construction and inspection of high voltage electrical installations. Visit our website and browse the wide range of standard catalogues in high voltage installations sectors. Regulations for the design construction and inspection of high voltage electrical installations take into account the fact that each installation will be different and are designed according to electrical engineering safety principles.
