Halogen Free Cable — IEC 60754 Zero Halogen XLPE/PE Insulated and LSZH or PE Sheathed Power and Control Cable with Verified Zero Halogen Acid Gas Emission for Data Centers, Control Rooms, Marine Vessels, Semiconductor Fabs, Cleanrooms, and Electronics Manufacturing Environments Requiring Corrosion-Free Fire Performance

Halogen free cable: IEC 60754 verified zero halogen (<0.5% HCl). XLPE or PE insulation, LSZH or PE sheath. 0.6/1kV power, 300/500V control. For data centers, marine, semiconductor fabs, cleanrooms, control rooms. Prevents HCl corrosion damage to electronics. CE, RoHS, DNV/ABS on request.

Key Features

IEC 60754-1 verified zero halogen — HCl emission <0.5% confirmed by laboratory testing of the finished cable; the cable contains no PVC, no chlorinated polyethylene, no brominated flame retardants, and no fluoropolymers — zero intentional halogen content in any cable component
XLPE (cross-linked polyethylene) or PE (polyethylene) core insulation — both are inherently halogen-free materials (polyethylene is C₂H₄ — carbon and hydrogen only); the insulation provides the cable's electrical performance: 90°C (XLPE) or 75°C (PE) continuous temperature rating, high insulation resistance, and low dielectric loss
LSZH or PE outer sheath — LSZH sheath for general halogen-free applications where low smoke and flame retardance are also required; PE sheath for installations where moisture resistance, UV stability, and mechanical properties are the primary requirements and the fire safety strategy does not demand LSZH smoke performance
Corrosion-free fire performance — the defining characteristic of halogen-free cable: when exposed to fire, the cable emits no HCl, HBr, or HF gases; these halogen acids, when combined with water (from firefighting, sprinklers, or atmospheric humidity), form hydrochloric, hydrobromic, or hydrofluoric acid that corrodes copper, solder, steel, and concrete — causing millions in post-fire damage that often exceeds the direct fire damage
Mandatory for data centers, semiconductor fabs, and control rooms — these environments contain high-value electronic equipment where the cost of HCl corrosion damage from a PVC cable fire would be catastrophic: server racks destroyed, wafer fabrication equipment contaminated, DCS/PLC systems corroded beyond repair; halogen-free cable is the only cable type permitted in these facilities
Available as power cable (0.6/1 kV, 1.5–300 mm², 1–5 cores) and control cable (300/500 V, 0.5–2.5 mm², 2–37 cores) — the full cable portfolio required for a halogen-free building or facility electrical installation
Flame retardant — LSZH sheathed cables pass IEC 60332-1-2 (single) and IEC 60332-3 (bunched) using mineral flame retardants (ATH/MDH); PE sheathed cables can be formulated with halogen-free intumescent flame retardants (ammonium polyphosphate, APP) to achieve IEC 60332 performance without halogen
Marine classification society approval available — DNV, ABS, Lloyd's Register, Bureau Veritas; halogen-free cable is mandatory for SOLAS passenger vessels and is specified for all new-build commercial vessels to prevent toxic gas and corrosion hazards in the confined shipboard environment

Applications

Data center power distribution and networking — halogen-free cable for the high-density cable installations from the UPS output to the server rack PDUs; the zero-halogen specification is mandatory in data center design standards (Tier III/IV, Uptime Institute) because HCl corrosion of server motherboards, connectors, and storage arrays from a cable fire would destroy the entire data hallSemiconductor fabrication facility (fab) — halogen-free cable for the extensive process tool power, control, and instrumentation wiring in cleanroom environments; halogen contamination from any source (including cables) can contaminate the silicon wafer fabrication process; halogen-free cable eliminates this contamination riskIndustrial control room and DCS/PLC cabinet wiring — halogen-free control and signal cable for the cable-intensive installations in process plant control rooms; if a fire occurs in a control room cable tray, PVC cable HCl gas would corrode every electronic card, terminal block, and connector in the room within hours — a multi-million dollar loss beyond the fire damageMarine and offshore vessel electrical installation — halogen-free cable for all shipboard circuits per SOLAS and IACS requirements; the confined, steel-enclosed shipboard environment means that PVC cable smoke and HCl gas in a fire would quickly fill compartments and cause casualties; halogen-free cable is the only cable type accepted for new-build passenger and naval vesselsMuseum, archive, and heritage building wiring — halogen-free cable to protect irreplaceable artifacts, documents, and building fabric from HCl corrosion damage in the event of a fire; the fire may damage the building, but the post-fire HCl corrosion from PVC cables would destroy what the fire sparedTelecommunications exchange and broadcasting center — halogen-free cable for the extensive DC power distribution, equipment rack wiring, and signal cabling in telecom exchanges and broadcast facilities where HCl gas from a PVC cable fire would corrode the copper connections on every distribution frame and equipment cardHospital and healthcare facility — halogen-free cable for the patient care areas, operating theatres, and medical equipment rooms where the combination of vulnerable occupants and high-value medical electronics demands the highest fire safety cable performance

Detailed Description

What Is Halogen Free Cable?

Halogen free cable is a power or control cable in which every organic component — core insulation, filler elements, binder tapes, inner covering, and outer sheath — is verified to emit less than 0.5% hydrogen chloride (HCl) equivalent halogen acid gases when combusted per IEC 60754-1. The cable contains no PVC (polyvinyl chloride — 57% chlorine by polymer weight), no chlorinated polyethylene, no brominated flame retardants, and no fluoropolymers (PTFE, FEP, PVDF) in any layer.

The distinction from LSZH cable is important: all LSZH cables are halogen-free, but not all halogen-free cables are LSZH. LSZH adds the "low smoke" requirement (IEC 61034-2, >60% light transmittance) and typically includes flame retardance (IEC 60332) through mineral fillers. A halogen-free cable with a PE (polyethylene) sheath is halogen-free but not LSZH — PE produces more smoke and is not inherently flame-retardant. The specification "halogen free" focuses on the absence of halogen — the characteristic that prevents post-fire corrosion damage.

The HCl Corrosion Problem — Why Halogen-Free Matters

When PVC cable burns, approximately 20–30% of the cable's weight is released as hydrogen chloride (HCl) gas. In the presence of moisture — from firefighting water, sprinkler activation, or atmospheric humidity — HCl dissolves to form hydrochloric acid. This acid:

  • Corrodes copper: The copper conductors, terminal blocks, busbars, and PCB traces in electrical and electronic equipment are attacked by HCl, forming copper chloride (CuCl₂) — a green, water-soluble corrosion product that destroys electrical connections
  • Corrodes solder: Tin-lead and tin-silver-copper solder joints on printed circuit boards are rapidly corroded by HCl, causing open circuits, increased resistance, and intermittent failures — often across thousands of solder joints on hundreds of circuit boards
  • Attacks steel and concrete: The structural steel reinforcement in concrete, the steel cable tray and ladder rack, the steel equipment cabinets — all corrode in the presence of HCl and moisture
  • Contaminates cleanrooms: In semiconductor fabrication, pharmaceutical manufacturing, and precision engineering, HCl contamination from a cable fire would require complete decontamination of the cleanroom environment — a process costing millions and taking months
The cost of HCl corrosion damage after a fire typically exceeds the direct fire damage by a factor of 2–10×. In a data center, a PVC cable fire in a single cable tray might cause $50,000 in direct fire damage but $500,000–$5,000,000 in corrosion damage to servers, switches, storage arrays, and structured cabling throughout the data hall — because the HCl gas disperses through the entire air-conditioned space, depositing acid on every exposed metal surface. Halogen-free cable eliminates this corrosion risk entirely.

Why Choose Yichi Halogen Free Cables

  • IEC 60754-1 verified — every cable component tested: The zero-halogen classification is not claimed from the material formulation — it is verified by combustion testing of the finished cable per IEC 60754-1. Every organic component of the cable must pass the <0.5% HCl test: insulation, fillers, tapes, inner covering, sheath. A single PVC filler yarn in an otherwise halogen-free cable would fail the test
  • XLPE insulation as standard — halogen-free by chemistry: XLPE is polyethylene (C₂H₄) cross-linked with peroxide — carbon and hydrogen only, zero halogens. The insulation's 90°C continuous rating and 250°C short-circuit rating provide the electrical performance; the halogen-free chemistry provides the fire safety
  • LSZH or PE sheath — select for the fire safety requirement: LSZH sheath for general halogen-free cable where flame retardance and low smoke are also required (data centers, semiconductor fabs, control rooms). PE sheath for halogen-free cable where moisture resistance and mechanical properties are the priority and flame retardance is provided by the installation method (underground, in metal conduit)
  • Marine classification society approval on request: DNV, ABS, Lloyd's Register, Bureau Veritas, CCS — the major international marine classification societies that certify cable for shipboard installation. Halogen-free cable is mandatory for SOLAS passenger vessels and is standard for all new-build commercial vessels. The marine approval verifies the cable's halogen-free performance plus the additional environmental and mechanical durability tests required for the marine environment
  • Full power and control cable range — halogen-free throughout: 0.6/1 kV power distribution to 300/500 V multi-core control — all manufactured with the same qualified halogen-free materials, one manufacturer, one quality system, one compliance certificate package for the building or facility
