Black 28 AWG 28/7/36 Multi-Strand PTFE Teflon - Silver Plated Copper wire Reel of 100 meters

PVC Insulated Copper Wires

Sunrom Product Code for Ordering:

7840

PTFE is a higher grade insulating polymer compared to other PVC wires. PTFE-insulated equipment/hookup wires are commonly used for internal wiring of various electronic and electrical equipment, as well as for other electrical uses. They are most suited for usage in high-frequency signal-processing equipment. Because of the uniformity of the insulation layer surrounding the conductor and the very low dielectric constant of PTFE, it is possible to transmit high-frequency signals with little signal losses as compared to other wires, resulting in high-quality signal transmission.

Choosing the correct size cable

It is important to choose the correct size cable when connecting to the mains. The wire has to be the correct size so that it can cope with the power demands of the device. The size stated for cables is given in mm2 and this measurement is actually the cross sectional area of the wire inside. The larger that area the higher the current it can carry.

If a cable is used which is too small for the amount of current passing through, it becomes dangerous. This results in the wire overheating and causing a serious safety risk. The table below gives typical values of cable size available plus corresponding current rating and maximum power ratings.
