Connection filter type FPE

Connection filters together with communication capacitors and high-frequency cable are designed for connection of sealing equipment to phase wires of power lines with voltage 35-750 kV, when organising high-frequency communication channels, for transmission of signals of telemechanics, relay protection, emergency control and telephone communication. The product provides: effective transmission of high-frequency electrical signals between high-frequency equipment and high-voltage line; safety of operating personnel and protection of low-voltage circuits of HF communication equipment from industrial frequency voltage and overvoltages during transients and lightning impulses. In FPE filters to increase the width of the operating frequency band and to ensure safety requirements are used broadband transformer circuits, and to improve reliability during transients are applied modern protective devices in the form of surge arresters and varistors.
