Tests and certification give great confidence!

Tests and certificates may not be something you think about very often, but when choosing cables for a project, it may be worthwhile to check if the cables you have chosen are tested. If they are not, you take a risk, which can cost greatly in the form of delays if the cables fail.

DanCables has developed a highly flexible aluminum cable for temporary installations. It is available with up to 5 conductors with rubber or PUR sheath, and the cable is designed according to class 5 and DIN VDE 0295 and IEC 60228 standards. The Alukaflex® rubber cable (which corresponds to a 90 ° C 07BN4-F cable) has obtained the DEKRA certificate and is therefore a good replacement for the H07RN-F rubber cable. At the same time, the Alukaflex® cable is up to 40% lighter in weight and significantly cheaper in purchases, since the prices of the raw materials are about three times as cheap when compared to copper.
