Save Current : PTFE Insulated wires have a lower resistance in comparison of PVC insulated wires. In V resistant, this wiring saves electricity. Save Space : The diameter of PTFE insulated wires are much less for the equivalent rate of PVC wires. It allows more numbers of wires into conduct housing. Long Lasting : PTFE Insulated wires have longer life than of b PVC Insulated wires. PTFE Insulation is mechanical stronger than PVC insulation. These wires are fire proof, heat proof, moisture proof, chemical proof and fungus proof, etc.
