ANNOTATSIYA
Ushbu maqolada Toshkent shahar tumanlari kesimida 35 kV kuchlanishli kabel liniyalarining shikastlanishi tahlili qilingan. Tahlil natijalariga ko’ra Toshkent shahar tumanlari kesimida elektr teshilishlari asosan Shayxontohur, Yunsabod, Yashnabod va Olmazor tumanlarida boshqa tumanlarga nisbatan ko’proq aniqlandi. Elektr teshilishlari asosan muftada -51%, kabelda - 43% va varonkada - 6% ni tashkil qildi. Bu shikastlanishlarning
kelib chiqishiga namlik,
korroziya, maxanik eskirish, ishlab chiqarishdagi kamchiliklar va boshqa sabablar asosiy omil bo’lib kelmoqda.

kabellar, shuningdek, muftalar va tugatishlar ishlamay qoladi. 35 kV kuchlanishli kabel liniyalarining shikastlanishining asosiy sabablari quyidagilar:
Avvalgi mexanik shikastlanish - 43%;
Qurilish va boshqa tashkilotlar tomonidan to'g'ridan-to'g'ri mexanik shikastlanish
- 16%;
O'rnatish vaqtida muftalar va so'nggi armaturalardagi nuqsonlar - 10%; Tuproqni cho'ktirish natijasida kabellar va muftalarga etkazilgan zarar - 8%;
