High Voltage Cable Installation Standards

Correct size and type.

High voltage cable installation standards.

A high voltage cable hv cable is a cable used for electric power transmission at high voltage a cable includes a conductor and insulation cables are considered to be fully insulated. High voltage withstand testing 39 time leakage test 41. 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. This means that they have a full rated insulation system which will consist of insulation semi con layers and a metallic shield.

Cables for rated voltages of 1 kv um 1 2 kv and 3 kv um 3 6 kv reference number iec 60502 1 2004 e international standard iec 60502 1 second edition 2004 04. 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. Design construction and inspection of high voltage electrical installations. Added section on live end.

Consult applicable information provided by national standards cable manufacturers and accessory and other suppliers. Rated 5 kv and above with high direct current voltage. Installation procedure for hv cables. 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.

Standardisedcable installation depth to minimum cover of750 mm and maximum depth of 1500mm section 14 9 added section 14 10 clarified marker tape and protective cover requirements section 14 11 clarified cable sealing exposed cables and terminated cables requirements section 14 13 14 14 and 14 15. High voltage flame retardant cable high voltage flame fire resistant cable low voltage flame retardant cable low voltage flame fire resistant cable technical information installation recommendations the following installation recommendations are in accordance with iec 60092 352 and the relevant class regulations.
