Cable systems for gaz sf6 ring main units

The ring main unit acts as a T-off point to a particular customer or transformer. Common in this application are mini substations where ring main units feed transformers, which in turn supply the low voltage network. Fig. 2 shows a typical Sulfr hexafluoride ring main unit commonly used today. NRS006 and SANS1874 are the recommended standards for ring main units.Get price
