TAILIEUCHUNG - High Voltage Xlpe Cable Systems - Technical User Guide

Calculation of the induced voltage Ui induced voltage in a cable system depends on the mutual inductance between the core and sheath, wires and eventually current cable length: LM is mutual inductivity core and shell (H / km). Inductivity interplay between core and shell LM calculated as follows: To install the formation of trefoil | Simpo PDF Merge and Split Unregistered Version - http HIGH VOLTAGE XLPE CABLE SYSTEMS Technical User Guide BRUGG CABLES Well connected.

General information on High Voltage Cable Systems Introduction The development of high voltage XLPE Cable Systems goes back to the 1960 s. Since then production and material technology have improved significantly providing reliable and maintenance-free products to the utility industry. At present numerous high voltage XLPE cable systems with nominal voltages up to 500 kV and with circuit lengths up to 40 km are in operation worldwide. Cable systems are equipped with accessories which have passed the relevant type tests pursuant to national and international standards such as long-duration tests. As one of the first XLPE cable manufacturers worldwide Brugg Cables passed a Prequalification Test on a 400 kV XLPE Cable System according to the relevant international standard IEC 62067 2001 . This test required one year of operation along with the thermal monitoring of all cables joints and terminations installed. It was successfully completed at CESI Laboratory in Milan Italy in 2004. .
