specifies requirements for thermosetting insulated and thermoplastic oversheathed cables rated up to <strong>450\/750V<\/strong> for power and lighting applications. These cables are specifically designed to emit low levels of smoke and corrosive gases when affected by fire, making them ideal for installations where human safety is paramount.<\/p>\n <p>This standard covers a number of British power and lighting cables with low emission of smoke and corrosive gas properties which were not harmonised into the BS EN 50525 series of standards. BS7211 cables provide a superior alternative to traditional PVC cables (referenced under BS6004) in fire-safety critical applications.<\/p>\n <\/div>\n <div class=\"content-cn\">\n <p><strong>BS7211<\/strong>\u662f\u4e00\u9805\u82f1\u570b\u6a19\u6e96\uff0c\u898f\u5b9a\u4e86\u984d\u5b9a\u96fb\u58d3\u9ad8\u9054<strong>450\/750V<\/strong>\u7684\u71b1\u56fa\u6027\u7d55\u7de3\u548c\u71b1\u5851\u6027\u8b77\u5957\u96fb\u7e9c\u7684\u8981\u6c42\uff0c\u9069\u7528\u65bc\u96fb\u529b\u548c\u7167\u660e\u61c9\u7528\u3002\u9019\u4e9b\u96fb\u7e9c\u7d93\u7279\u6b8a\u8a2d\u8a08\uff0c\u5728\u706b\u707d\u5f71\u97ff\u4e0b\u91cb\u653e\u4f4e\u91cf\u7159\u9727\u548c\u8150\u8755\u6027\u6c23\u9ad4\uff0c\u975e\u5e38\u9069\u5408\u4eba\u8eab\u5b89\u5168\u81f3\u95dc\u91cd\u8981\u7684\u5b89\u88dd\u5834\u6240\u3002<\/p>\n <p>\u8a72\u6a19\u6e96\u6db5\u84cb\u4e86\u591a\u7a2e\u82f1\u570b\u96fb\u529b\u548c\u7167\u660e\u96fb\u7e9c\uff0c\u9019\u4e9b\u96fb\u7e9c\u5177\u6709\u4f4e\u7159\u4f4e\u8150\u8755\u6027\u6c23\u9ad4\u7279\u6027\uff0c\u5c1a\u672a\u7d0d\u5165BS EN 50525\u7cfb\u5217\u6a19\u6e96\u3002\u5728\u6d88\u9632\u5b89\u5168\u95dc\u9375\u61c9\u7528\u4e2d\uff0cBS7211\u96fb\u7e9c\u662f\u50b3\u7d71PVC\u96fb\u7e9c\uff08\u53c3\u7167BS6004\uff09\u7684\u512a\u8d8a\u66ff\u4ee3\u54c1\u3002<\/p>\n <\/div>\n <\/div>\n\n <div class=\"highlight-box\">\n <div class=\"highlight-title\">Key Standard Information | \u95dc\u9375\u6a19\u6e96\u4fe1\u606f<\/div>\n <p><strong>Full Title:<\/strong> Electric cables \u2014 Thermosetting insulated and thermoplastic sheathed cables for voltages up to and including 450\/750V for electric power and lighting and having low emission of smoke and corrosive gases when affected by fire<\/p>\n <p style=\"color: var(--text-muted); margin-top: 0.5rem;\"><strong>\u5b8c\u6574\u6a19\u984c\uff1a<\/strong>\u96fb\u7e9c \u2014 \u984d\u5b9a\u96fb\u58d3450\/750V\u53ca\u4ee5\u4e0b\u7684\u71b1\u56fa\u6027\u7d55\u7de3\u548c\u71b1\u5851\u6027\u8b77\u5957\u96fb\u7e9c\uff0c\u7528\u65bc\u96fb\u529b\u548c\u7167\u660e\uff0c\u706b\u707d\u6642\u5177\u6709\u4f4e\u7159\u548c\u4f4e\u8150\u8755\u6027\u6c23\u9ad4\u6392\u653e\u7279\u6027<\/p>\n <\/div>\n <\/section>\n\n \n <section class=\"content-section\">\n <div class=\"section-header\">\n <span class=\"section-number\">2<\/span>\n <h2 class=\"section-title\">Technical Specifications<span class=\"section-title-cn\">\u6280\u8853\u898f\u683c<\/span><\/h2>\n <\/div>\n\n <div class=\"table-container\">\n <table class=\"data-table\">\n <thead>\n <tr>\n <th>Parameter \u53c3\u6578<\/th>\n <th>Specification \u898f\u683c<\/th>\n <th>Test Standard \u6e2c\u8a66\u6a19\u6e96<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>\n <span class=\"param-name\">Voltage Rating<\/span>\n <div class=\"param-cn\">\u984d\u5b9a\u96fb\u58d3<\/div>\n <\/td>\n <td><span class=\"param-value\">300\/500V, 450\/750V<\/span><\/td>\n <td>BS 7211<\/td>\n <\/tr>\n <tr>\n <td>\n <span class=\"param-name\">Conductor Material<\/span>\n <div class=\"param-cn\">\u5c0e\u9ad4\u6750\u6599<\/div>\n <\/td>\n <td><span class=\"param-value\">Plain Annealed Copper<\/span><\/td>\n <td>BS EN 60228<\/td>\n <\/tr>\n <tr>\n <td>\n <span class=\"param-name\">Conductor Class<\/span>\n <div class=\"param-cn\">\u5c0e\u9ad4\u985e\u5225<\/div>\n <\/td>\n <td>\n <span class=\"param-value\">Class 1 (1mm\u00b2 – 2.5mm\u00b2)<\/span><br>\n <span class=\"param-value\">Class 2 (4mm\u00b2 – 10mm\u00b2)<\/span>\n <\/td>\n <td>BS EN 60228<\/td>\n <\/tr>\n <tr>\n <td>\n <span class=\"param-name\">Insulation Material<\/span>\n <div class=\"param-cn\">\u7d55\u7de3\u6750\u6599<\/div>\n <\/td>\n <td><span class=\"param-value\">XLPE (Cross-Linked Polyethylene)<\/span><\/td>\n <td>BS 7655<\/td>\n <\/tr>\n <tr>\n <td>\n <span class=\"param-name\">Sheath Material<\/span>\n <div class=\"param-cn\">\u8b77\u5957\u6750\u6599<\/div>\n <\/td>\n <td><span class=\"param-value\">LSZH (Low Smoke Zero Halogen)<\/span><\/td>\n <td>BS 7655-6.1 (Type LTS4)<\/td>\n <\/tr>\n <tr>\n <td>\n <span class=\"param-name\">Max.

These cables are specifically designed to emit low levels of smoke and corrosive gases when affected by fire, making them ideal for installations where human safety is paramount.<\/p>\n <p>This standard covers a number of British power and lighting cables with low emission of smoke and corrosive gas properties which were not harmonised into the BS EN 50525 series of standards.
