Fire raw materials mainly include the internal use of LED display wire, power supply, external protective structure of fire materials and plastic kits two aspects:
1th: In most of the LED display applications, LED display unit area of the larger, its use of electricity, wire power stability also has a higher demand. Many wire products, the use of the wire to meet the requirements of the GB can ensure its safety and stability, its requirements have three points: the wire core for copper conductor, wire core section tolerance in the standard range value, wrap the core of the rubber insulation and flame-retardant to meet the standard, compared to the general copper clad aluminum wire core, wire core cross-sectional area of small, insulating rubber grade is not enough wire, power performance is more stable, not prone to short-circuit;
2nd: Through the UL certification of power products is also the choice of similar products when the best choice, its effective conversion rate can ensure that the power load safety and stability, in the external environment temperature hot conditions, can also work properly;
