Overview
Technical features
- TIP gas-insulated SSVT is suitable for outdoor installations
- Primary winding is connected directly to high voltage (HV)and ground, while the secondary winding supplies lowvoltage (LV) or medium voltage (MV)
- Cooling method: GNAN (gas natural, air natural)
- HV terminals made of high conductivity aluminium. Can becylindrical or flat type (e.g. NEMA)
- Fiber-glass insulator with silicon rubber sheds andcreepage distance ≥ 25 mm/kV
- Enclosure made of aluminium alloy containing cores,primary and secondary windings
- Magnetic cores made of laminated steel with orientedgrains and high level of permeability
- Windings made of electrolytic copper
- Optional measuring windings
- Tested according to IEC 61689 and IEC 60076 or IEEEC57.13 and C57.12
- Suitable for applications in very low temperatures ( -50 oC)with mixed gas
Applications of TIP
1.Supplying auxiliary power in a substation away fromdistribution grid
In isolated areas, SF6 insulated station service voltagetransformers can effectively replace the functions of a powertransformer, optimizing the investment with the effective need ofpower. TIP is perfectly suited to switching substations, seriescompensation, solar plants, wind farms, etc;
2.Providing electricity to remote areas
TIP is the ideal solution for the electrification of rural areaswhere limited power needs of remote villages cannoteconomically justify the installation of a conventional substationor the extension of a distribution grid.
