Product Description

SF6 insulatedcurrent transformer- Air Insulated Switchgears

SF6 insulated current transformer are usedto convert high transmission line currents (up to 6000 A) 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 reliablecurrent 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.Current transformers also ensure suitable electrical insulation between highvoltage and low voltage measuring equipment.

Our gas-insulated current 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.
