FAQ
1. What is the difference between soft silicone wire and ordinary PVC wire?
Flexibility: Silicone wire is softer and suitable for frequent bending.
Heat resistance: Silicone wire is resistant to high temperature (up to 200°C), while PVC wire is usually only resistant to 70-105°C.
Durability: Silicone is resistant to aging and corrosion, and has a longer lifespan.
2. Can this wire be used for high current transmission?
Yes, but it needs to be selected according to the wire diameter (AWG value). For example:
AWG12 (cross-sectional area of about 3.3mm²) can carry 20-25A current.
AWG18 (cross-sectional area of about 0.82mm²) is suitable for 5-10A.
3. Is the silicone wire flame retardant?
High-quality silicone wires have self-extinguishing properties (they do not continue to burn after being removed from an open flame), but they are not completely flame-resistant; models with added flame retardants can offer higher levels of fire resistance if needed.
4. How to distinguish the quality of silicone wire?
Look at the material: the conductor should be bright and free of oxidation, and the silicone layer should be uniform and free of bubbles.
Test flexibility: the insulation layer should not crack after repeated bending.
Temperature resistance test: no deformation or odor release at high temperatures.
5. Can silicone cables be used outdoors or in humid environments?
Yes. Silicone has excellent waterproof and moisture-proof properties, but long-term exposure to ultraviolet rays may age, so it is recommended to add a protective sleeve.
6. What is the withstand voltage value of the wire?
The withstand voltage range of common silicone wires is 300V-600V (such as UL3135 standard). Please check the product specifications for details.
7. How to connect the soft silicone wire?
Welding: Use a high-temperature soldering station (silicone is heat-resistant, but avoid long-term high temperature to burn the insulation layer).
Crimping: Use appropriate terminals to ensure firm contact.
Note: Avoid using low-quality tape, and heat shrink tubing is recommended to protect the joint.
8. What should I pay attention to when storing wires?
Avoid scratches from sharp objects, keep away from strong acid/alkaline environments, and store in a cool and dry place.
