Discussion on the difference between UL1424 and LPCB cables by engineers from Lilutong.
UL1424 和 LPCB 是两种不同的电缆认证标准，主要区别在于认证机构、应用范围和市场侧重点。
UL1424 and LPCB are two different cable certification standards, with the main differences being the certification body, application scope, and market focus.
认证机构与标准
UL1424：由美国保险商试验所（UL）制定，属于美标认证，主要用于消防报警系统电缆，如火灾报警、应急照明、排烟系统等。 该标准强调电缆在火灾情况下的阻燃性能和电气稳定性。
Certification bodies and standards
UL1424: Developed by Underwriters Laboratories (UL) in the United States, it is an American standard certification mainly used for fire alarm system cables, such as fire alarm, emergency lighting, smoke exhaust systems, etc. This standard emphasizes the flame retardant performance and electrical stability of cables in the event of a fire.
LPCB：由英国损失预防认证委员会（LPCB）颁发，是国际认可的消防安全认证，尤其在欧洲和公共工程项目中具有权威性。其认证更注重电缆在火灾中的整体性能（如耐火性、烟雾毒性等）。
LPCB: Issued by the Loss Prevention Certification Board (LPCB) in the UK, it is an internationally recognized fire safety certification, particularly authoritative in Europe and public works projects. Its certification focuses more on the overall performance of the cable in a fire (such as fire resistance, smoke toxicity, etc.).
应用场景差异
UL1424：
典型应用包括美标消防系统，如高层建筑、机场、隧道等场所的火灾报警、消防水泵、应急照明电路。
例如，利路通UL1424电缆需满足300V额定电压和105℃耐温要求。
Differences in application scenarios
Typical applications include American standard fire protection systems, such as fire alarms, fire pumps, and emergency lighting circuits in high-rise buildings, airports, tunnels, and other places.
For example, the Lilutong UL1424 cable needs to meet the requirements of 300V rated voltage and 105 ℃ temperature resistance.
LPCB：
常见于欧洲及国际大型公共设施（如地铁、医院）的消防工程，要求电缆通过更严格的耐火测试（如BS 6387标准），例如：利路通LPCB 电缆能确保火灾时持续供电。
Commonly used in fire engineering for large public facilities in Europe and internationally, such as subways and hospitals, cables are required to pass stricter fire resistance tests (such as BS 6387 standard). For example, the Lilutong LPCB cable can ensure continuous power supply in the event of a fire.
市场与合规性
UL1424：主要面向北美市场，是进入美国消防系统的强制认证。
Market and Compliance
UL1424: Mainly targeting the North American market, it is a mandatory certification for entering the US fire protection system.
LPCB：在欧洲、中东等地区更具影响力，尤其适用于政府或跨国项目招标。
LPCB: More influential in regions such as Europe and the Middle East, especially suitable for government or multinational project bidding.
总结
若项目需符合美标或北美市场，优先选择UL1424认证电缆；若涉及欧洲或国际高标准消防工程，则需LPCB认证。两者均针对消防场景，但认证体系和地域适用性不同。利路通均能生产对应电缆且有认证。
summary
If the project needs to comply with American standards or the North American market, UL1424 certified cables are preferred; If it involves high standard fire engineering in Europe or internationally, LPCB certification is required. Both are aimed at firefighting scenarios, but their certification systems and regional applicability are different. Lilutong is capable of producing corresponding cables and has certification.
