CORRELATION BETWEEN ELECTRICAL AND MECHANICAL CHARACTERISTICS OF CABLES WITH RADIATION-MODIFIED INSULATION ON THE BASIS OF A HALOGEN-FREE POLYMER COMPOSITION
Introduction. The high saturation of the cable routes of nuclear and thermal stations, wind parks and solar power plants, on-board systems imposes stringent requirements in the field of fire safety of cables, which makes it necessary to use highly flame retardant halogen-free compositions.

The high saturation of the cable routes of nuclear and thermal stations, wind parks and solar power plants, on-board systems imposes stringent requirements in the field of fire safety of cables, which makes it necessary to use highly flame retardant halogen-free compositions. The introduction of flame retardants causes the mandatory modification (crosslinking) of the polymer matrix. Purpose. Determination of the optimal radiation dose based on the correlation between the mechanical and electrical characteristics of a radiation-modified halogen-free ethylene vinyl acetate copolymer with high-strength flame retardant insulation cables. Methodology. Mechanical and electrical tests of samples of radiation-modified cables with a copper conductor cross section of 1.0 mm2 and a halogen-free filled insulation based on an EVA copolymer with a thickness of 0.7 mm have been performed. Results. A strong correlation is established between the elongation at break and the tensile strength, between the insulation resistance and the breakdown voltage. It is shown that at the optimum value of the irradiation coefficient in the range from 7 to 5, the insulation resistance increases more than twice, and the breakdown voltage at the direct current is increased by 1.3 times. The elongation at break is within the allowed values. Исследовано влияние коэффициента облучения ускоренными электронами с энергией 0,5 МэВ на механические и электрические характеристики кабельной высоконаполненной антипиреннами изоляции из не распространяющей горение безгалогенной композиции на основе сополимера етиленвинилацетата. Установлена сильная корреляционная связь между относительным удлинением при разрыве и прочностью при растяжении, между сопротивлением изоляции и пробивным напряжением. Показано, что при оптимальном значении коэффициента облучения в диапазоне от 7 до 5 сопротивление изоляции возрастает более чем в два раза, а пробивное напряжение на постоянном токе – в 1,3 раза. Относительное удлинение при разрыве остается в пределах допустимых значений.
