1. Refer to fire resistance performance standards: Fire-resistant wires must meet relevant national fire resistance performance standards, such as GB12666.6-2010.
2. Pay attention to the selection of insulation materials: Choosing suitable insulation materials can effectively improve the performance of fire-resistant wires, such as silicone rubber, polyimide, and fluoroplastics.
3. Consider the material of the protective layer: Generally, coating the surface of the wire with a flame-retardant material can improve its fire resistance. Commonly used flame-retardant materials include nano-polymers and heat stabilizers.
4. Conduct on-site performance tests: When purchasing fire-resistant wires, conduct heat tests and bending tests to check their fire resistance performance, ensuring that the purchased wires meet your usage requirements.
