Assessment of material analysis for Halogen free flame retardant concentric neutral type Power cable

난연성 동심중성선 전력 케이블의 재료에 대한 평가 기술

The test methods on materials of electrical power cable are used in accordance with 25 specifications of IEC, ASTM, ICEA, KS and KEPCO Spec. The validation of test methods were checked and stablished by solving the problems occurred during the test. These tests are flammability, degree of acidity of gases, amount of halogen acid gas, smoke density, oxygen index, amount of ion in semiconductor, void, amber, contaminant and water tree, crosslinked density. Then the performance of power cable made by A, B, C and D company were evaluated and compared.
