Standard Overview
標準概述British Standard BS6004:2012+A1:2020 specifies requirements for low voltage PVC insulated and PVC sheathed cables with voltage ratings up to 300/500V. These cables are essential for fixed wiring in building electrical systems, covering power supply and lighting applications in domestic, commercial, and light industrial environments.
The standard encompasses various cable types including the widely-used Twin & Earth (T&E) cables (6242Y, 6243Y), single-core double-insulated cables (6181Y), and Arctic grade cables (318-A series) designed for extreme low-temperature applications down to -40°C.
BS6004 cables feature annealed copper conductors conforming to BS EN 60228, with insulation components rated for maximum sustained conductor temperature of 70°C and short-circuit temperature of 160°C (max 5 seconds).
英國標準BS6004:2012+A1:2020規定了額定電壓至300/500V的PVC絕緣和PVC護套低壓電纜的技術要求。這些電纜是建築電氣系統固定佈線的核心組件，廣泛應用於住宅、商業和輕工業環境的電力供應與照明系統。
該標準涵蓋多種電纜類型，包括廣泛使用的雙芯帶地線電纜（T&E，型號6242Y、6243Y）、單芯雙絕緣電纜（6181Y），以及專為極端低溫環境設計的北極級電纜（318-A系列），可在低至-40°C的溫度下正常工作。
BS6004電纜採用符合BS EN 60228標準的退火銅導體，絕緣組件額定最高持續導體溫度為70°C，短路溫度為160°C（最長5秒）。
BS6004 is a comprehensive standard that defines the construction, performance, and identification of everyday building cables, ensuring what runs through walls and ceilings is safe, compliant, and reliable for domestic and light industrial applications.
