Gas Insulated Switchgears

Toshiba’s SF6 Gas Insulated Switchgear (GIS) units offer many superior features. We have delivered over 6 000 GIS systems since 1969 and all continue to provide reliable service in network operation. They are compact, able to operate in many conditions, use the latest in 3D technology and provide both electric field analysis and gas flow analysis.

Surge Arresters

With leading technology and decades of experience, we manufacture a variety of surge arresters which ensure high performance and reliability. Our surge arresters can be applied to a variety of systems including substation equipment, AC-DC converters, railway system and power distribution units ranging from 3.3kV to 800kV systems. They incorporate TNR elements (Toshiba Non-linear Resistor ZnO Elements) with superior non-linear voltage-current characteristics, ensuring top quality and reliability.

Power Electronics

These systems can deliver HVDC and FACTS equipment with world-class efficiency that ensure stability on electric distribution networks. The HVDC system provides optimized DC transmission systems and equipment to handle the need for electric power transmission on long-distance, high-volume lines (including submarine cabling) and variable frequency lines, as well as AC lines with difficult to control power flow among other applications.

The FACT system (SVC and STATCOM) improves stability of power lines and assures quality with functions to suppress voltage fluctuation and oscillation caused by increased power source dispersion and abrupt load variations. It also has SVC and STATCOM, which are effective in counteracting voltage flicker.

Power Transformers

To satisfy the ever-increasing electricity demand, transmission voltages and capacity are continuously increasing the production of transformers to meet requirements. We broke the previous Japanese high-voltage-capacity record with the development and commercialisation of an 800kV transformer. We have also developed other products, such as Advanced Site Assembly (ASA) transformers, which were developed to meet requirements for transportation limitation or environmental conformity, and gas-insulated transformers which are compact, environmentally friendly and non-flammable.

Switchgears

Toshiba offers a wide range of highly reliable switchgears and have done so since 1926. Our Metalclad Air Insulated Switchgears (VEZ and VDZ) are air-insulated switchgears for the mid-voltage range of 12kV and 24kV. They are made in compartmentalised functional units that feature internal arc-discharge mechanisms and are interlocking.

The VEZ and VDZ switchgears have internal flappers to discharge the high-voltage of arc accidents to protect operators from these accidents and are equipped with complete interlocking mechanisms needed to prevent human error during operation.

Our Solid Insulated Switchgears (SIS) are designed for mid-voltage 24kV and 36kV applications. The solid insulation of the SIS uses high-performance epoxy resin developed with our proprietary technology. Compared to previous materials, it has much better mechanical strength, toughness, heat resistance, and dielectric strength. The SIS is the next generation of switchgear that do not use SF6 gas to help prevent global warming.
