A wire that has a gauge of around 40AWg up to 28AWG and with a 30 volts voltage rating, is called a thin wire. It is a very small hoop up wire and is often seen used in highly sophisticated machinery, like mobile phones. XLPE or XLPVC is usually the material used for its insulation because it is very convenient to process. The use of these materials also guarantees a longer shelf life for the wire.
The primary benefit of XLPE / XLPVC Thin Cable Wire has amazing shrinkage resistance performance while welding on the sophisticated panel. When the insulating material shrinks, the inner conductor inside will be exposed to air, which in turn will result in accelerated oxidization. And if the data of the stripping is not accurate at the same time. The thin wire should be cut, stripped, and tinned on both ends.
Compared to Silicone Rubber Insulation, XLPE & XLPVC insulation can be much thinner. And the inner space of the device is limited.
As for FEP Insulation, FEP Insulation can be thinner than XLPE & XLPVC insulation. The rated temperature can also reach 200℃. However, the FEP thin wire is hard to fix with glue, which will cause the joint between the wire and the panel to be more fragile. Meanwhile, the signal protection is worse compare to XLPE and XLPVC insulation.
Compared to XLPVC thin wire, XLPE thin wire is Low Smoke Halogen Free Wire which is more environment friendly compare to XLPVC thin wire. But this comes at a slightly higher cost than XLPVC thin wire.
On the other hand, XLPE and XLPVC as a Cross-linked thermoset material, can greatly improve the performance of anti-aging & high-temperature resistance and insulation anti-shrinking.
