What is BS7919 Cable?
什麼是BS7919電纜？
Flexible industrial cables for equipment and appliances with a voltage rating of up to 450/750V. 適用於設備和電器的柔性工業電纜，額定電壓高達450/750V。
Introduction 簡介
Cables manufactured in accordance with British Standard BS7919 are designed for ordinary duty applications when of a voltage rating 300/500V and heavy duty installations for voltage ratings of 450/750V. They are generally used in environments requiring both flexibility and resistance to mechanical abrasion.
This includes equipment connection such as power generators, lighting systems, portable machinery, and industrial equipment. This standard was withdrawn in 2012 and superseded in part by BS EN 50525, however it is still widely referred to in the cable industry.
依據英國標準BS7919製造的電纜，在額定電壓300/500V時設計用於普通負載應用，在額定電壓450/750V時用於重型安裝。這類電纜通常用於同時需要柔韌性和抗機械磨損性的環境中。
其應用包括發電機、照明系統、便攜式機械和工業設備的連接。該標準於2012年撤銷，部分被BS EN 50525取代，但在電纜行業中仍被廣泛引用。
“High-performance cables for port machinery, built for durability and flexibility in demanding environments. Designed for cranes, unloaders, and gantry systems, ensuring reliable operation in demanding conditions.”
