Advanced HVDC XLPE cable and accessories
9th IET International Conference on Advances in Power System Control, Operation and Management (APSCOM 2012), 2012We have found that the issues in the DC properties of conventional cross linked polyethylene (XLPE) can be solved through the DC-XLPE insulating material. The DC-XLPE's major advantages against conventional XLPE are as follows: High volume: resistivity: Low space charge accumulation: High DC breakdown strength: Long DC life time The HVDC cable system ...

Effect of protrusions in HVDC cables
IEEE Transactions on Dielectrics and Electrical Insulation, 2012This paper presents an analysis to determine the effect of the stress enhancement factor due to the presence of protrusions in the semiconductor shields of HVDC cables. The theoretical analysis of the electric field containing protrusions is based on a harmonic solution for the electric field for spherical and spheroidal protrusions.

World record HVDC submarine cables
IEEE Electrical Insulation Magazine, 1994On Oct. 1, 1993 a new 350 kV/440 MW HVDC cable was commissioned between Norway and Denmark. This 127 km-long, Skagerrak 3 cable was manufactured bv Alcatel Kabel Norge. It was installed at a record maximum sea depth of 530 m. During the summer of 1994 a 250 km-long, 450 kV/600 MW HVDC cable will be installed across the Baltic Sea from Sweden to Germany.

Insulation materials for HVDC polymeric cables
IEEE Transactions on Dielectrics and Electrical Insulation, 2017Polymeric insulation materials have been very successfully used in the extruded high voltage alternating current (HVAC) cables underground power transmission for a long time. Although the development history of extruded polymeric HVDC cables is not very long, it has shown great advantages in power transmission over HVAC cables and other kinds of HVDC ...

Electric Stresses in a HVDC Cable Through Joint
IEEE Power Engineering Review, 1984Longitudinal and radial stresses in a hvdc cable through joint are computed using a finite difference method. The joint and associated cable are rated at 266 kV d. c., 1200A and assumed buried to a depth of l.lm in homogeneous soil of thermal resistivity 1.2 deg C-m W-1.

HVDC Extruded Cables-Parameters for Determination of Stress
IEEE Power Engineering Review, 1984The distribution of electric stress in the insulation of a h.v.d.c. cable is determined by the resistivity of the insulation, which is dependent both on temperature and stress. In the present work an attempt is made to quantify for polymeric insulation the parameters of an equation for resistivity of the form used for paper/oil, i.e. ?= ??exp-(??+ sE).

HVDC Cable Accessory Insulation
2017HVDC cables have shown great advantages for long-distance, high-power underground or underwater transmission. The performance of cable accessories, as an essential part of the HVDC networks, is a great concern to the reliability of the system. However, Cable accessories made of ethylene-propylene-diene terpolymer (EPDM), which are considered to be the ...

Discharging Characteristics of a HVDC Test-Cable
2019 14th Conference on Industrial and Information Systems (ICIIS), 2019In HVDC power transmission, power cables are taking the place of overhead lines at a rapid rate. While testing HVDC power cables, manufacturers often encounter difficulty of handling, as a prior knowledge of the time at which the power cable would discharge completely is not known. This paper explores the discharging time of cables of different lengths
