Sf6 Insulated Voltage Transformers-air Insulated Switchgears

Product Description

SF₆ insulatedvoltage transformers-Air Insulated Switchgears

SF₆ insulated voltage transformers are usedto convert high transmission line voltages (up to 800kV) to standardized lowand easily measurable values, which will be used for metering, protection andcontrol of the high voltage system. As such, the need for accurate and reliablevoltage transformation is essential.

The reliability and security of Trench gas-insulatedinstrument transformers is based on over 50 years of innovation withgas-insulated units operating under a wide range of environmental conditions.Voltage transformers also ensure suitable electrical insulation between highvoltage and low voltage measuring equipment.

Our gas-insulated voltage transformers are compliant to thelatest international safety standard requirements in terms of explosion-proof,insulating material multiple chopped ageing, seismic qualification and extremetemperature conditions.

Modern production and testing facilities guarentee not onlyshort delivery times but also a reliable operation for many years.
