Nenvitech SF6 room Disposal for transformers

After cooling down, these active subfluorides will quickly return back to SF6 gas. Therefore, SF6 gas which is used under sealing for a long time will not decrease or deteriorate, although under the effect of arc extinguishing several times. The amount of arc decomposition depends on water content contained in SF6 gas.

  • Electrical Transformer End-of-Life Hazardous Waste Removal

    Utilities use massive step-up transformers to increase voltage (aka tension) in order to push electricity more efficiently through long-distance transmission lines—hence the term “high tension wires.” They use step-down transformers, for example, to reduce voltage to the relatively safe and familiar 120/220 VAC we have in our homes.
