International Standard IEC 60502-1 from the International Electrotechnical Commission sets out the specification for power cables with extruded insulation with a voltage rating of 1kV to 30kV. This standard also covers their accessories. The cables must have an extruded solid insulation and may contain longitudinal water-blocking properties such as swellable tapes and powders if the installation conditions demand it.
Many of the cables manufactured in accordance with IEC 60502 are designed for local power distribution, and for power and auxiliary controls. Where additional mechanical protection is provided, the cables are suitable for installation in masonry and concrete. The water-blocking properties are important to prevent water ingress when used in wet conditions.
IEC60502-2 cable
It should be noted that IEC 60502-2 excludes cables for special conditions such as those manufactured for use in overhead lines, mining, nuclear power plants, marine and submarine applications. Where this is the case, technical specifications refer to cables being manufactured 'Generally to IEC 60502-2'.
This Standard is divided into the following parts:

| 1 |
1kV to 3kV |
| 2 |
6kV to 30kV |
| 3 |
Reserved for future development |
| 4 |
Test requirements on accessories for cables with a voltage rating from 6kV to 30kV |
Scope of IEC 60502-1
Part 1 of this international Standard specified the construction, dimensions and test requirements of cables with extruded solid insulation with a rated voltage ranging between 1kV and 3kV for fixed installations such as distribution networks or industrial installations. Some of the cables covered by IEC 60502 have flame spread-reducing or Low Smoke Zero Halogen (LSZH) properties when exposed to fire.

Some cables meeting the requirements of IEC 60502 benefit from armoured layers, making them able to withstand a higher degree of mechanical stress than comparative sized unarmoured cables. Various types of armour are specified, such as concentric copper wire screens and/or helically wound copper tape as required in the N2XCH cable.
