Halogen-Free Options: Replacing Nexans RHEYFLAT®-H with Standard LSZH Flat Mining Cables for Tunnel Applications
无卤阻燃选型：以标准 LSZH 扁平矿用电缆替代 Nexans RHEYFLAT®-H 用于隧道应用
1. Executive Summary 概述
In tunnels, underground mines, and other confined subsurface environments, the consequences of a cable fire are dramatically amplified. Limited ventilation means that toxic smoke and corrosive gases generated by burning cable materials — particularly those containing halogens such as chlorine and bromine — can accumulate rapidly, blocking evacuation routes and corroding critical electronic safety systems within minutes. This is precisely why international standards and national mining codes increasingly mandate the use of Low Smoke Zero Halogen (LSZH) cables in these environments. （在隧道、地下矿井等密闭地下环境中，电缆火灾的后果会急剧放大。有限的通风意味着含卤素电缆燃烧产生的有毒烟雾和腐蚀性气体会在数分钟内积聚，阻塞疏散通道并腐蚀关键电子安全系统。因此，国际标准和各国矿用法规日益强制要求在此类环境中使用 LSZH 电缆。）
The Nexans RHEYFLAT®-H series represents the halogen-free variant within the RHEYFLAT® flat cable family, employing halogen-free insulation and sheathing compounds that comply with IEC 60754-1 (halogen content) and IEC 61034 (smoke density) requirements. While it is a well-established product, project engineers and mine operators frequently encounter practical barriers to its procurement — including long lead times from European production facilities, minimum order quantities, and limited availability of certain core configurations. （Nexans RHEYFLAT®-H 系列是 RHEYFLAT® 扁平电缆家族中的无卤型号，采用符合 IEC 60754-1 和 IEC 61034 要求的无卤绝缘和护套料。虽然该产品成熟可靠，但项目工程师和矿山运营商在采购中经常遇到交货周期长、最小起订量高等实际障碍。）
Anhui Feichun Special Cable Co., Ltd. (安徽飞纯特种电缆有限公司) produces a full range of LSZH flat cables — including both festoon-type and armoured configurations — that are engineered as equivalent replacements for the RHEYFLAT®-H series in tunnel and mining applications. This technical bulletin provides an in-depth comparison of materials, fire performance, electrical parameters, and regulatory compliance to assist specifying engineers in making an informed substitution decision. （安徽飞纯特种电缆有限公司生产全系列 LSZH 扁平电缆，包括滑触线型和铠装型配置，专为替代 RHEYFLAT®-H 系列在隧道和矿山中的应用而设计。本文将从材料、防火性能、电气参数和法规合规性等方面进行深入对比。）
2. Why Halogen-Free Matters in Tunnel & Mining Environments 无卤阻燃为何对隧道和矿山至关重要
2.1 The Halogen Hazard in Confined Spaces 密闭空间中的卤素危害
Standard PVC-insulated cables contain approximately 25–29% chlorine by weight. 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 2–4 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 ≥ 4.3 and conductivity ≤ 10 µS/mm — values that PVC cables cannot achieve. （标准 PVC 绝缘电缆含约 25–29% 的氯（按重量计）。PVC 燃烧时释放氯化氢（HCl）气体，对人体呼吸道有急性毒性，且对金属表面和电子设备具有严重腐蚀性。IEC 60754-2 要求燃烧气体 pH ≥ 4.3、电导率 ≤ 10 µS/mm —— PVC 电缆无法达到此标准。）
2.2 Smoke Density and Evacuation Visibility 烟密度与疏散可见度
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 m³ enclosed chamber. To be classified as “low smoke,” a cable must maintain a minimum light transmittance of 60% during the test — 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. （比有毒气体更直接危险的是浓烟导致的能见度丧失。IEC 61034-2 “3 米立方体测试” 要求低烟电缆在测试中保持最低 60% 的光透过率。LSZH 电缆通常可达 65%–85%，而 PVC 电缆可能低于 15%。）
2.3 Regulatory Landscape for Tunnel Cabling 隧道电缆法规概况
Multiple international and national regulations now mandate or strongly recommend LSZH cables in underground and tunnel environments. The EU Construction Products Regulation (CPR) EU 305/2011, through harmonized standard EN 50575, requires cables in construction works to be classified by Euroclass (Aca through Fca), with many tunnel authorities mandating a minimum of Cca-s1,d1,a1 for power cables. China’s GB 31247-2014 classifies flame-retardant cables into A/B/C/D grades, with B1 grade explicitly requiring low smoke (≥ 60% transmittance), halogen-free (≤ 5 mg/g halogen acid gas), and low toxicity. Singapore’s BCA mandates LSZH cables conforming to IEC 60754/61034 for subway, hospital, and government building installations. （多项国际和国家法规现已强制或强烈建议在地下及隧道环境中使用 LSZH 电缆。EU CPR 法规要求建筑工程电缆按欧洲等级分类；中国 GB 31247-2014 将阻燃电缆分为 A/B/C/D 等级，B1 级明确要求低烟（透光率 ≥ 60%）、无卤（卤酸气体 ≤ 5 mg/g）和低毒性。）
3. Nexans RHEYFLAT®-H Series Overview Nexans RHEYFLAT®-H 系列概述
The Nexans RHEYFLAT®-H is a halogen-free variant of the RHEYFLAT® flat cable platform. It replaces the standard PCP (polychloroprene/Neoprene) rubber compounds used in the RHEYFLAT®-N and RHEYFLAT®-Y series with special halogen-free elastomeric or thermoplastic polyolefin compounds for both insulation and outer sheath. The mechanical design — flat-profile construction with parallel-arranged conductors — 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. The table below summarizes the key nominal parameters of the RHEYFLAT®-H series as published in Nexans handling cable catalogues. （Nexans RHEYFLAT®-H 是 RHEYFLAT® 扁平电缆平台的无卤变型。它将标准 PCP 橡胶化合物替换为特殊的无卤弹性体或热塑性聚烯烃化合物，用于绝缘和外护套。机械设计保持不变——扁平结构、平行排列导体，适用于滑触线系统和电缆拖链。）

8. Tunnel & Underground Application Scenarios 隧道与地下工程应用场景
8.1 TBM (Tunnel Boring Machine) Trailing Cables 盾构机拖缆
Tunnel boring machines in metro, highway, and rail tunnel construction require flat trailing cables to supply power and control signals to the TBM cutterhead motors, conveyor drives, and ancillary systems. These cables must withstand continuous drag over long distances (often 1–3 km), exposure to ground water, and significant mechanical abrasion. The LSZH flat cable’s fire safety credentials are essential because TBMs operate in confined tunnel bores where evacuation distance to the portal can exceed 2 km. The Feichun FC-FLAT-LSZH is available in high cross-section configurations (up to 4 × 95 mm² on request) to carry the substantial currents required by TBM drives. （盾构机在地铁、公路和铁路隧道施工中需要扁平拖缆为刀盘电机和输送机驱动供电。LSZH 扁平电缆的防火安全资质在盾构掘进的密闭隧道中至关重要，因为疏散距离可能超过 2 km。飞纯 FC-FLAT-LSZH 可提供高截面配置（最高 4 × 95 mm²，可定制）。）
8.2 Underground Mine Festoon & Conveyor Systems 地下矿山滑触线与输送机系统
In underground coal and hard-rock mines, festoon cable systems supply power to shuttle cars, continuous miners, and belt conveyor drives. Mining safety authorities — including MSHA (U.S.), DGMS (India), and the Chinese State Administration of Work Safety — mandate fire-resistant or LSZH cable in underground operations. The flat cable profile minimizes headroom intrusion inside mine drifts with limited clearance. Feichun offers an optional orange-sheathed mining variant for high-visibility identification as required by many mine operators. （在地下煤矿和硬岩矿中，滑触线电缆系统为穿梭车、连续采矿机和皮带输送机驱动供电。各国矿山安全机构强制要求地下作业使用耐火或 LSZH 电缆。飞纯可提供可选的橙色护套矿用型号，用于高可见度标识。）
8.3 Metro & Railway Tunnel Installations 地铁与铁路隧道安装
Railway tunnel electrification and signalling systems demand cables that meet the European standard EN 45545-2 for fire safety of rolling stock and infrastructure materials. EN 45545 classifies tunnel operations under Operation Category 2 (OC2) — vehicles operating in underground sections and tunnels — which maps to Hazard Level 2 or 3, requiring stringent smoke density, flame spread, and toxicity performance. The Feichun FC-FLAT-LSZH cable, with its IEC 60332-3 Cat. A/C compliance and IEC 61034 low smoke performance, provides the fire performance data needed to support EN 45545 requirement set R15 (cables for interior use) and R22–R23 (cables for exterior use on carbody). （铁路隧道电气化和信号系统要求电缆符合 EN 45545-2 防火安全标准。EN 45545 将隧道运营归类为 OC2 类别，对应危险等级 2 或 3，要求严格的烟密度、火焰蔓延和毒性性能。飞纯 FC-FLAT-LSZH 电缆的 IEC 60332-3 和 IEC 61034 合规数据可支持 EN 45545 要求集 R15 和 R22–R23。）
8.4 Hydroelectric Power Station Tunnels 水电站隧道
Intake tunnels, penstocks, and underground powerhouse caverns in hydroelectric installations combine high humidity, occasional water ingress, and limited evacuation routes — making LSZH cables a safety-critical specification. The FC-FLAT-LSZH’s AD7 water resistance rating (per IEC 60529) and its halogen-free fire performance make it suitable for both fixed installation along tunnel walls and festoon-fed mobile equipment within the powerhouse. （水电站引水隧洞、压力管道和地下厂房结合了高湿度、偶发渗水和有限疏散路线——使 LSZH 电缆成为安全关键规格。FC-FLAT-LSZH 的 AD7 防水等级和无卤防火性能使其适用于隧道固定敷设和厂房内移动设备滑触线供电。）

|---|---|---|---|---|
| HCl Emission (% by weight) | > 15% | 8–12% | < 0.5% | IEC 60754-1 |
| Combustion Gas pH | 1.5 – 2.5 | 2.0 – 3.5 | ≥ 4.3 | IEC 60754-2 |
| Gas Conductivity (µS/mm) | > 100 | 30 – 80 | < 10 | IEC 60754-2 |
| Smoke Transmittance (%) | 5 – 15% | 20 – 40% | 65 – 85% | IEC 61034-2 |
| Flame Spread (bundled, 2.5m limit) | May exceed 2.5 m | Typically ≤ 2.5 m | Typically ≤ 1.5 m | IEC 60332-3-24 |
10. Why Specify Feichun FC-FLAT-LSZH as an Equivalent Alternative 为何选择飞纯 FC-FLAT-LSZH 作为等效替代

Test certificates accompany each shipment. （每批生产均按 IEC 60754-1/2、IEC 61034 和 IEC 60332 系列标准进行测试。测试证书随货提供。）
Dimensional Compatibility 尺寸兼容 — The FC-FLAT-LSZH series matches the cross-sectional envelope (width × height) of the Nexans RHEYFLAT®-H, ensuring direct drop-in replacement in existing festoon trolleys, cable carrier trays, and conduit entries without mechanical modification. （FC-FLAT-LSZH 系列的截面尺寸与 Nexans RHEYFLAT®-H 匹配，确保在现有滑触线小车和电缆托架中直接替换，无需机械改动。）
Accelerated Delivery 加速交付 — Integrated production in Anhui Province — from copper rod drawing through XLPE cross-linking and LSZH compounding — enables standard lead times of 2–4 weeks, versus 10–20 weeks for European-sourced LSZH flat cables. （安徽省一体化生产——从铜杆拉拔到 XLPE 交联和 LSZH 混炼——标准交期 2–4 周，远低于欧洲产 LSZH 扁平电缆的 10–20 周。）
Custom Mining Variants 定制矿用变型 — Orange sheath, armoured (SWA/AWA) options, combined power + pilot core configurations, and earth monitoring pilot cores for mining leakage protection systems are available as standard custom options. （橙色护套、铠装（SWA/AWA）选项、动力+控制芯组合配置，以及用于矿用漏电保护系统的接地监测芯均可作为标准定制选项。）
