What is BS8436 Standard Cable? 什麼是BS8436標準電纜？
Multicore electric cables with metallic screening and LSZH sheath, rated 300/500V, designed for concealed installation in building voids, partitions and walls with nail penetration resistance.
帶金屬屏蔽和低煙無鹵護套的多芯電纜，額定電壓300/500V，專為建築空腔、隔牆和牆壁內的隱蔽安裝設計，具有釘子穿透耐受性。
Overview 概述
British Standard BS8436 specifies requirements for multicore electric cables with low emissions of smoke and corrosive gases when subjected to fire. The standard covers 2-core, 3-core, and 4-core cables with an uninsulated full-size circuit protective conductor of tinned annealed copper and metallic screening. These cables are specifically designed for use in building voids, partitions and walls where there is a risk of damage or penetration from nails, screw fixings, and similar fasteners.
英國標準BS8436規定了在火災中煙霧和腐蝕性氣體排放量低的多芯電纜的要求。該標準涵蓋2芯、3芯和4芯電纜，具有鍍錫退火銅的非絕緣全尺寸電路保護導體和金屬屏蔽。這些電纜專門設計用於建築空腔、隔牆和牆壁內，這些地方存在被釘子、螺絲固定件和類似緊固件損壞或穿透的風險。
Cables manufactured to BS8436 meet the 18th Edition of the Wiring Regulations BS 7671 sections 522.6.202 to 522.6.204, which relate to concealed cables installed at a depth of less than 50mm. This ensures compliance with current UK electrical installation requirements.
按照BS8436製造的電纜符合《佈線規程》BS 7671第18版第522.6.202至522.6.204節的要求，這些條款涉及安裝深度小於50mm的隱蔽電纜。這確保符合當前英國電氣安裝要求。
Key Safety Features 主要安全特性
BS8436 cables are engineered to be electrically fail-safe in the event they are penetrated by a nail or screw. The standard requires cables to pass a nail penetration test six times while maintaining functionality on each occasion. This critical safety feature protects building occupants and prevents electrical hazards during construction and renovation work.
BS8436電纜經過工程設計，在被釘子或螺絲穿透時能夠實現電氣故障安全。該標準要求電纜通過六次釘子穿透測試，並在每次測試中保持功能。這一關鍵安全特性保護建築物內人員並防止施工和翻新工作期間的電氣危險。
6× Nail Penetration Test
Must pass nail penetration test six consecutive times while maintaining circuit functionality.必須連續六次通過釘子穿透測試，同時保持電路功能。
Low Smoke Zero Halogen
LSZH sheathing reduces smoke emissions and eliminates corrosive halogen gases during fire.低煙無鹵護套減少煙霧排放，消除火災期間的腐蝕性鹵素氣體。
Metallic Screen Protection
Metallic or laminated tape provides electrical and mechanical protection for concealed installations.金屬或層壓帶為隱蔽安裝提供電氣和機械保護。
CPR Compliant
Designed for fixed building installations, fully compliant with Construction Products Regulation.專為建築固定安裝設計，完全符合建築產品法規。
Cable Construction 電纜結構
BS8436 specifies the protective metallic or laminated metallic tape screen to be applied longitudinally or helically (or as a combination of the two), with the metallic side of the tape in direct contact with the uninsulated circuit protective conductor. The sheathing must have low smoke zero halogen properties, reducing smoke emissions when subjected to fire and eliminating halogens such as chlorine gas.
BS8436規定保護性金屬或層壓金屬帶屏蔽應縱向或螺旋形（或兩者組合）敷設，帶的金屬側與非絕緣電路保護導體直接接觸。護套必須具有低煙無鹵特性，在火災中減少煙霧排放並消除氯氣等鹵素。
