PTFE Insulated Silver Plated Copper Wire

P.T.F.E. insulated equipment/hookup wires are high temperature electrical wires generally used for internal wiring of various electronic and electrical equipments and other electrical purposes and are available in wide range of sizes and colours. They are most suitable to use for wiring of equipment involving high frequency signals. Uniform thickness of insulation around the conductor and very low dielectric constant of P.T.F.E. enables the transmission of high frequency signals with minimum signal losses. It results in high quality signal transmission as compared to ordinary wires. PT.F.E. wires are manufactured in conformance with JSS, mil-Wand BSS specifications as desired. P.T.F.E. equipment wires are available in various working voltages:
Type Et for 250 volts,
Type E for 600 volts,
Type EE for 1000 V.
