Line traps air core, dry type up to 800 kV

Line traps are used in transmission and distribution networks around the world./Global/Grid/Resources/Content/296d8616-6f0a-4044-878c-71c96592cfc4.jpg
Line traps are a key component in PLC (Power Line Carrier) systems used for remote control signals, voice communication, remote metering
and control between substations in the electrical T&D network.

Our engineers have extensive experience in designing and supplying line traps for system voltages up to 800 kV, and the company has
supplied customers all over the world for more than 25 years.
