Abstract |
XLPE cable is using insulator for Cross Linked Polyethylene(XLPE), because insulation Performance is superior and easy comparatively. Need systematization of accident transaction for electrical equipment accident, It is no disposal standard for defect of manufacture and second to accidents. in this paper deals with the change of XLPE cable insulation To understand the electrical properties of XLPE insulation Made of XLPE block sample, Penetration fracture Sample and flashover sample. Ogura needles having tip radius of 10[㎛] were inserted into each sample. AC voltage of 1[㎸/sec] increased at 60[㎐] were apple to breakdown sample and flashover sample. AC voltages of 12[㎸], 17[㎸] at 60[㎐] were applied to XLPE block sample. The electrical properties of specimens were measured were Treasured from initiation of tree and breakdown to their characteristics were analyzed. |
