GB ISO 36KV Gas Insulated Switchgear Medium Voltage Ring Main Unit
SF6 RMU HXGN15 Series 12KV GIS GB ISO IEC
Product Introduction
General
This type of RMU switchgear using SF6 as an arc extinguishing medium with double open contacts, 3 working-position and rotating contact which placed in an epoxy resin shell of a reinforced structure. Each gas tank must be passed helium-leak detection before being filled with 0.045Mpa SF6 (Inspect any leakage to ensure can be installed vertically or horizontally).
