When PVC combusts, it releases hydrogen chloride (HCl) gas, which is both acutely toxic to humans (causing respiratory tract burns at concentrations above 50 ppm) and severely corrosive to metallic surfaces and electronics. In a tunnel or mine drift with limited cross-sectional airflow, HCl concentrations can reach dangerous levels within 2\u20134 minutes of cable ignition. Standard IEC 60754-2 quantifies this hazard by measuring the pH and conductivity of combustion gases: a cable meeting IEC 60754-2 requirements must produce gases with pH \u2265 4.3 and conductivity \u2264 10 \u00b5S\/mm \u2014 values that PVC cables cannot achieve.\n <span class=\"cn-i\">\uff08\u6807\u51c6 PVC \u7edd\u7f18\u7535\u7f06\u542b\u7ea6 25\u201329% \u7684\u6c2f\uff08\u6309\u91cd\u91cf\u8ba1\uff09\u3002PVC \u71c3\u70e7\u65f6\u91ca\u653e\u6c2f\u5316\u6c22\uff08HCl\uff09\u6c14\u4f53\uff0c\u5bf9\u4eba\u4f53\u547c\u5438\u9053\u6709\u6025\u6027\u6bd2\u6027\uff0c\u4e14\u5bf9\u91d1\u5c5e\u8868\u9762\u548c\u7535\u5b50\u8bbe\u5907\u5177\u6709\u4e25\u91cd\u8150\u8680\u6027\u3002IEC 60754-2 \u8981\u6c42\u71c3\u70e7\u6c14\u4f53 pH \u2265 4.3\u3001\u7535\u5bfc\u7387 \u2264 10 \u00b5S\/mm \u2014\u2014 PVC \u7535\u7f06\u65e0\u6cd5\u8fbe\u5230\u6b64\u6807\u51c6\u3002\uff09<\/span><\/p>\n\n <h3>2.2 Smoke Density and Evacuation Visibility <span class=\"cn-i\">\u70df\u5bc6\u5ea6\u4e0e\u758f\u6563\u53ef\u89c1\u5ea6<\/span><\/h3>\n <p>Even more immediately dangerous than toxic gas is the loss of visibility caused by dense smoke. The “3-meter cube test” defined in IEC 61034-2 measures the minimum light transmittance through smoke generated by burning a 1-metre cable sample inside a 3 m\u00b3 enclosed chamber. To be classified as “low smoke,” a cable must maintain a minimum light transmittance of 60% during the test \u2014 meaning evacuees can still see exit signs and pathway markings at a distance. LSZH cables using halogen-free polyolefin compounds typically achieve transmittance values between 65% and 85%, whereas PVC cables may drop below 15%, effectively creating a zero-visibility condition.\n <span class=\"cn-i\">\uff08\u6bd4\u6709\u6bd2\u6c14\u4f53\u66f4\u76f4\u63a5\u5371\u9669\u7684\u662f\u6d53\u70df\u5bfc\u81f4\u7684\u80fd\u89c1\u5ea6\u4e27\u5931\u3002IEC 61034-2 “3 \u7c73\u7acb\u65b9\u4f53\u6d4b\u8bd5” \u8981\u6c42\u4f4e\u70df\u7535\u7f06\u5728\u6d4b\u8bd5\u4e2d\u4fdd\u6301\u6700\u4f4e 60% \u7684\u5149\u900f\u8fc7\u7387\u3002LSZH \u7535\u7f06\u901a\u5e38\u53ef\u8fbe 65%\u201385%\uff0c\u800c PVC \u7535\u7f06\u53ef\u80fd\u4f4e\u4e8e 15%\u3002\uff09<\/span><\/p>\n\n <h3>2.3 Regulatory Landscape for Tunnel Cabling <span class=\"cn-i\">\u96a7\u9053\u7535\u7f06\u6cd5\u89c4\u6982\u51b5<\/span><\/h3>\n <p>Multiple international and national regulations now mandate or strongly recommend LSZH cables in underground and tunnel environments.

It replaces the standard PCP (polychloroprene\/Neoprene) rubber compounds used in the RHEYFLAT\u00ae-N and RHEYFLAT\u00ae-Y series with special halogen-free elastomeric or thermoplastic polyolefin compounds for both insulation and outer sheath. The mechanical design \u2014 flat-profile construction with parallel-arranged conductors \u2014 remains identical, allowing the cable to be used in festoon systems, e-chain cable carriers, and direct connection to mobile mining equipment with bending in one plane only. The conductor construction follows IEC 60228 Class 5 (flexible stranded copper), and core identification conforms to HD 308 S2.

Limited ventilation means that toxic smoke and corrosive gases generated by burning cable materials \u2014 particularly those containing halogens such as chlorine and bromine \u2014 can accumulate rapidly, blocking evacuation routes and corroding critical electronic safety systems within minutes.
