What is BS IEC 62895- HVDC power transmission cables about?
BS IEC 62895 is an International Standard that discusses High voltage direct current (HVDC) power transmission.
BS IEC 62895 specifies test methods and requirements for HVDC transmission power cable systems, employing cables with extruded insulation and their accessories, for fixed land installations, for rated voltages up to and including 320 kV.
The requirements apply to single-core cables in combination with their accessories, outdoor and terminations for gas-insulated systems, joints, and asymmetric joints for usual conditions of installation and operation, but not to special cables and their accessories.
Who is BS IEC 62895 - HVDC power transmission cables for?
BS IEC 62895 on high voltage direct current transmission is relevant to:
- HVDC transmission power cable manufacturers
- Electrical cable and high-voltage equipment manufacturers
- Electric power transmission line operators and installers
- Electrical engineers
- Electric substations
- Quality control and testing personnel
Why should you use BS IEC 62895- HVDC power transmission cables?
HVDC allows power transmission between AC transmission systems that are not synchronized. HVDC helps increase the system stability, by preventing cascading failures from propagating from one part of a wider power transmission grid to another.
BS EN IEC 60633 provides best industry guidance on dimensional values, designations, cable insulating materials, cable characteristics, and type tests as well as pre-qualification tests for cables and on the main insulation of prefabricated accessories. The type tests include:
- Bending test
- Heating cycle voltage test
- Superimposed impulse voltage test
The results of these tests provide manufacturers an indication about the electrical insulation properties of their products, and whether or not they are capable of withstanding voltage stresses without the occurrence of power system disturbances.
Compliance with the test methods recommended by BS IEC 62895, you can demonstrate the reliability of your products, and establish conformity to the safety and performance requirements of the system.
