Long-life Xlpe Insulated Power Cable
Crosslinked polyethylene (XLPE) has become the globally preferred insulation for power cables, both for distribution and transmission system applications. This insulation system provides cost efficiency in operation and procurement, as well as lower environmental and maintenance requirements when compared to older impregnated paper systems. The purpose of this paper is to outline some of the de...
متن کاملA Methodology for the Assessment of Hvdc-xlpe Cable Insulation
The purpose of this work is to present and to discuss a methodology for the assessment of materials intended to HVDC-XLPE cables, particularly as regards the evaluation of the effects of material formulation on space charge accumulation within the insulation. Sample design, testing method and protocol and criteria used for the material evaluation are specifically considered. It will be shown th...
متن کاملThe Conduction Characteristics of Electrical Trees in XLPE Cable Insulation
Depending on the morphology of the material and applied voltage frequency, three kinds of electrical trees can exist in cross-linked polyethylene (XLPE) cable insulation, which are conducting, non-conducting, and mixed trees with different growth mechanisms. It is suggested that when the needle is inserted into large spherulites, conducting trees will form in those spherulites; when it is inser...
متن کاملInvestigation of electrical treeing in cable grade crosslinked polyethylene (XLPE) insulations
Using PC-based on-line monitoring system, extensive measurements were performed in insulation blocks cut from the crosslinked polyethylene (XLPE) insulation of 36, 69 and 132 kV rated cables produced in Saudi Arabia. A needle-plane electrode system was used with a needle radius of 10 m. The role of 'applied voltage step-time duration' and associated time resolved initiation and growth of diffe...
متن کاملOn-line Partial Discharge Monitor System of XLPE Power Cable Based on Virtual Instrument
High voltage XLPE power cable is a very important part of power system. The degree of electric-tree aging in the cable can be estimated effectually by measuring partial discharge. An on-line partial discharge monitor system of XLPE power cable was developed based on the virtual instrument designing conception. This system has the advantage of wide analog bandwidth, excellent anti-interference a...
