IEC 60840 Cable
The International Electrotechnical Commission’s standard IEC 60840 references the requirements for cables and cable accessories with a voltage rating of between 30kV (Um 36kV) and 150kV (Um 170kV).
The cables are of either single core or individually screened three-core cables but, as with the lower voltage standard IEC 60502, it excludes cables for special applications such as submarine and mining.
These high voltage cables are designed for fixed installations and suitable for the primary distribution of power. These cables have an outer sheath of High Density Polyethylene (HDPE) which offers a balance between abrasion resistance and flexibility.
To achieve compliance with this international standard, the cables are subject to regular type test sequences, simulated to represent a 30 year service lifetime on a cable sample of at least 1 metre. Unlike in the IEC 60502 Part 2 testing, IEC 60840 sees voltage applied during the burner heating cycles.
Eland Cables supplies a comprehensive range of high voltage and medium voltage cables to a number of industries ranging from railways to infrastructure and power transmission.
