PTFE insulated equipment/ hookup wires are generally used for internal wiring of various electronic and electrical equipments and other electrical purposes. They are most suitable to use in equipments involving for high frequency signals. Uniformity of insulation thickness around the conductor and very low dielectric constant of PTFE enables the transmission of high frequency signals with minimized signal losses as compared to other wires resulting in high quality signal transmission. Wires are manufactured in conformance with JSS, mil-W, BSS specifications as desired.
PTFE equipment wires are available in different working voltages:
- ET for 250 Volts
- E for 600 Volts
- EE for 1000 Volts
However wires can be made for higher voltages also.
