Water Resistant Cables: Types and Classification


Classification of electric cables according to the level of water protection

Electrical cables are used in various applications or installations, often under adverse environmental conditions. AD protection (against water) establishes to what extent an electrical cable can be exposed to moisture, according to UNE 20460-3:1996 standard.

  • AD1 PROTECTION: the probability of presence in water is negligible

Clasificación para las influencias externas

Location in which the walls do not generally show traces of water, but can appear in small periods, for example, in the form of steam and which dries quickly thanks to good ventilation.


  • AD2 PROTECTION: possibility of vertical drops of water falling

Location in which water vapour occasionally condenses in the form of water drops or when vapour may occasionally be present.


  • PROTECTION AD3: possibility of water droplets falling at an angle of more than 60º to the vertical

Location in which water vapour appears as a continuous film on the walls and/or floors.

Top Cable has the following cables with AD3 protection:

  • AD4 PROTECTION: possibility of water jets in all directions.

Location where the equipment may be subject to water projections; applies, for example, to certain luminaires or cabinets installed outdoors.
