UNE 211632-6A:2023

This standard specifies the characteristics, design, manufacturing, supply and tests that single-pole HV cables (and cable systems) with rated voltage 26/45 (52) kV, 36/66 ( 72.5) kV, 64/110 (123) kV, 76/132 (145) kV and 87/150 (170) kV with high modulus ethylene propylene (HEPR) dry insulation and polyolefin or high modulus polyethylene sheath. density shall meet.Type tests on the cable system (cable and accessory) are optional for voltages below 76/132 (145) kV.The cable types in this part of the standard are:Type 1: Cable with a polyolefin or high-density polyethylene compound sheath, without special properties when it comes to reaction to fire.Type 2: Cable with a polyolefin compound sheath with low halogen content and special properties against reaction to fire. The minimum class of reaction to fire is Eca.Type 3: Cable with a polyolefin compound sheath with low halogen content and special properties against reaction to fire. The minimum fire reaction class is Cca-s1b,d2,a1.The definition of performance regarding the reaction to fire of the cables object of this standard has been made in accordance with the Delegated Regulation (EU) 2016/364 of the Commission, of July 1, 2015, regarding the classification of the properties of reaction to fire of construction products in accordance with Regulation (EU) No. 305/2011 of the European Parliament and of the Council.
