HV&EHV Cable And Cable System Standards
HV&EHV cable systems are designed to meet requirements in international and/or national standards. Some of these are listed below.

IEC
HV&EHV cable systems specified according to IEC(International Electrotechnical Commission) are among many other standards accepted. Some frequently used standards are:
IEC 60228
Conductors of insulated cables.
IEC 60287
Electric cables - Calculation of the current rating.
IEC 60332
Tests on electric cables under fire conditions.
IEC 60840
Power cables with extruded insulation and their accessories for rated voltage above 30 kV (Um=36 kV) up to 150 kV(Um=170 kV). Test methods and requirements.
IEC 60853
Calculation of the cyclic and emergency current rating of cables.
IEC 61443
Short-circuit temperature limits of electric cables with rated voltages above 30 kV (Um=36 kV)
IEC 62067
Power cables with extruded insulation and their accessories for rated voltage above 150 kV (Um=170 kV) up to 500 kV(Um=550 kV). Test methods and requirements

CENELEC
In Europe, cable standards are issued by CENELEC.(European Committee for Electrotechnical Standardization.) They are as a rule implementations of the IEC specifications. Special features in design may occur depending on national conditions.
HD 632
Power cables with extruded insulation and their accessories for rated voltage above 36 kV (Um=42 kV) up to 150 kV (Um=170 kV)."

ICEA/ANSI/AEIC
North America cables are often specified according to ICEA /ANSI/AEIC
S-97-682
Standard for utility shielded power cables rated 5-46 kV.
AEIC CS7-93
Specifications for crosslinked polyethylene insulated shielded power cables rated 69 through 138kV
ANSI/ICEA S-108-720-2004
Standard for extruded insulated power cables rated above 46 through 345 kV.
