Sıkça Sorulan Sorular

RVD-72.5 hangi yalıtım gazını kullanmaktadır ve SF₆ içermez mi?

CO₂, O₂ ve düşük oranda C4F7N katkı maddesinden oluşan bir karışım olan g³ gazını kullanır. İçeriğinde SF₆ bulunmaz ve SF₆'ya kıyasla küresel ısınma potansiyelini %99 oranında azaltır.

RHB-72.5 hangi IEC standardına uymaktadır?

Dış mekan iletim uygulamaları için IEC 62271-100 yüksek gerilim şalt tesisatı standardına uygundur.

RHB-72.5 kurulumu için temel yük gereksinimleri nelerdir?

Temel statik yükü: 120000N; yatay dinamik yük 40000N, dikey dinamik yük 220000N (ekipman öz ağırlığı dahil). Her bir temel yüzeyinin yükseklik farkı 2 mm'yi aşmamalıdır.
