Tavsif：
ROCKWILL mahsulot sifatiga va ishlab chiqarish texnologiyasiga katta e'tibor qaratadi va har bir bosqichni aniq va dastlabki ravishda bajaradi. Faqat izolyatsiya gazini ishlatish orqali issiqlikga solishtirilgan tuzuk havo, azot, oksidan va toza havo umumiy tarzda solishtiriladi. To'g'ridan-to'g'ri toza havo tanlanadi va u SF6 ni almashtirish uchun tanlanadi. Mahsulotning asosiy klyuchli qismi yangi vakuum ark sovg'uv qamriga minkon paketli shaklda ishlab chiqarilgan bo'lib, juda dastlabki ravishda ishlab chiqarilgan aylanuvchi uchinchi joylashuvli klyuch bilan qo'shilgan, butun struktura sodda va kompaktna; to'liq sig'langan gaz shkatulasi SF6 ni toza havoga almashtiradi, elektr maydoni taqsimotining yuqori afzalliklari bor va jami shkafning qismi parchalanishi 5pC dan past; zink zarblanish metall qopqoq usuli orqali ishlab chiqarilgan jarayon mekanizmi tuzlama sinovida 168 soatdan oshib ketdi va eng uzun xizmat muddati 30000 marta bo'lishi mumkin.
