BLL 20 kV (24)
Description
BLL is a suspension line suitable for free conducting with a construction voltage at nominal 20 kV.
Description
Standards
International : EN 50182; EN 50397Description
BLL is a non-compacted longitudinally water blocked, 1-leading line designed according to SS 424 14 32. The conductor is of different material depending on cross-section: Cross-section 62 and 99 mm² is made of FeAl. The cross-sections 159 mm² and 241 mm² exist in AlMgSi type Al 7. The cable may maximum be loaded to a conductor temperature 70°C. The conductor is covered with PE and of one layers with a black weather proof PE. The line is marked manufacturer / type / year+month / metre marking.
Lifemark(TM) recycling marking
The external surface of the outer sheath is embossed with a text which specifies all components in the polymers and prepares the cable for future recycling.
Testing
The conductor is tested in accordance with SS-EN 50397 and 50182.
Quality and environmental management system
Certified according to ISO 9001, IRIS, ISO/TS 16949 and ISO 14001.
