The main purpose of the work presented in this paper was to experimentally examine possible enhancement of water treeing caused by remnant mechanical stresses, frozen-in during the manufacturing process of extruded XLPE power cables. The experiments were performed using 3m long samples of 12 kV XLPE...

This paper considers the problems with induced currents in copper screens and aluminium laminate, consequences and improvements for a 24 kV watertight XLPE cable system. Repeated faults on a heavily loaded new cable system installed for the generators of a Norwegian hydropower generation station res...

There is an increasing demand for subsea electrical power transmission in the oil- and gas industry. Electrical power is mainly required for subsea pumps, compressors and for direct electrical heating of flowlines. The majority of subsea processing equipment is installed at water depths less than 10...

This paper presents an evaluation and results from a water aging test performed at 10 kV/mm - 500 Hz of a HV 52 kV XLPE core. Water permeation tests and associated modelling have been performed on power cores with a PE-sheath only and a non-impervious water barrier to evaluate the effect of the “sem...

This Handbook is revised and somewhat updated from the original issue of 1994. The Handbook gives recommendations about choices and correct use of overvoltage protection in lightning prone area, corrosion protection, and choices of open or tight ACC line configurations, and measures to protect the i...

This paper presents results from laboratory water tree experiments performed on samples of commercially available 6/10 kV XLPE insulated cables. The main purpose of the investigation was to examine possible water tree enhancement, due to mechanical tension of the insulation. During water tree ageing...

This paper presents results from water tree ageing experiments of XLPE cables exposed to both voltage stress and mechanical tension. The main purpose was to examine possible water tree enhancement due to dynamic mechanical tension forces, likely to occur in power cables connected to floating off-sho...
