Mineral Insulated Cable (MI Cable) – Fire-Resistant, High-Temperature Industrial Power & Signal Solution

As a premium fire-safe cable solution for critical industrial applications, our Mineral Insulated Cable (MI Cable) is engineered with a unique structure of copper conductors, mineral insulation (magnesium oxide, MgO), and copper sheath. Combining exceptional fire resistance, high-temperature tolerance, and mechanical robustness, this cable delivers reliable power and signal transmission even in extreme environments – making it the ideal choice for industries requiring maximum safety, durability, and long-term performance.

Core Features & Technical Advantages

1. Superior Fire Resistance & Safety

• Fire-Safe Design: The mineral insulation (MgO) is inherently non-combustible, smoke-free, and halogen-free. In case of fire, the cable maintains power/signal transmission for 1–3 hours (depending on specifications, compliant with IEC 60331/BS 6387), enabling safe evacuation, emergency system operation, and critical equipment shutdown.

• No Toxic Emissions: Contains no halogen, PVC, or flammable materials, emitting no toxic gases or corrosive fumes during combustion. Complies with IEC 60754-2 (halogen content) and IEC 61034 (smoke density) standards, ensuring safety for personnel and equipment in enclosed spaces.

• Flame-Retardant & Self-Extinguishing: The copper sheath and mineral insulation prevent flame propagation, eliminating fire spread risks in industrial facilities, high-rise buildings, and critical infrastructure.

2. Extreme Temperature Tolerance

• Wide Operating Temperature Range: Functions reliably in temperatures from -200℃ to +700℃ (short-term exposure up to 1000℃ for emergency scenarios). Adapts to high-heat industrial environments (e.g., furnaces, smelters) and low-temperature applications (e.g., cold storage, outdoor winter conditions).

• Thermal Shock Resistance: Resists rapid temperature changes without structural damage or performance degradation, making it suitable for dynamic thermal environments.

3. Industrial-Grade Durability & Reliability

• Mechanical Robustness: The seamless copper sheath provides exceptional mechanical protection against impact, abrasion, compression, and rodent damage. It withstands harsh handling during installation and operation in industrial settings.

• Corrosion Resistance: The copper sheath is naturally corrosion-resistant; optional coatings (e.g., PVC, PE, or fluoropolymer) are available for enhanced resistance to chemicals, moisture, and saltwater (ideal for coastal, chemical, or marine applications).

• Long Service Life: Mineral insulation and copper conductors are resistant to aging, oxidation, and degradation, ensuring a service life of over 50 years – reducing maintenance costs and downtime for industrial clients.

4. Stable Power & Signal Transmission

• High Conductivity: High-purity copper conductors minimize power loss and signal attenuation, supporting efficient transmission of both high-voltage power (up to 10kV) and low-voltage control signals.

• EMC Immunity: The copper sheath acts as a natural electromagnetic shield, blocking EMI/RFI interference without additional shielding layers. Ensures stable performance in high-interference industrial environments (e.g., near motors, transformers, or heavy machinery).

• Waterproof & Moisture-Proof: The dense mineral insulation and sealed copper sheath prevent moisture ingress, making the cable suitable for wet environments (e.g., underground, underwater, or humid industrial areas).

5. Customizable Specifications & Installation Flexibility

• Configurable Options:

• Conductor sizes: 1.5mm²–400mm² (single-core or multi-core configurations: 1C–5C)

• Sheath materials: Bare copper, PVC-sheathed, PE-sheathed, or fluoropolymer-sheathed

• Voltage ratings: 450/750V, 6/10kV, 12/20kV (customizable for high-voltage applications)

• Lengths: Custom cut-to-length available, with optional terminations (e.g., cable lugs, connectors)

• Easy Installation: Flexible enough for bending (minimum bending radius of 6×–10× cable outer diameter) and routing in confined spaces. Compatible with standard cable glands and fittings, simplifying integration into existing industrial systems.

Application Fields (B2B Industry Focus)

Ideal for industries and scenarios requiring fire safety, high-temperature resistance, and reliability:

• Industrial Manufacturing: Steel mills, smelters, chemical plants, refineries, and power plants (critical power/signal transmission in high-heat, flammable, or corrosive environments).

• Building & Infrastructure: High-rise buildings, hospitals, data centers, airports, and subway systems (emergency lighting, fire alarm systems, sprinkler controls, and critical power backup).

• Energy & Utilities: Nuclear power plants, wind farms, solar energy systems, and power distribution networks (high-temperature, fire-safe power transmission).

• Marine & Offshore: Ships, offshore platforms, and coastal facilities (corrosion-resistant, waterproof, and fire-safe cable solutions).

• Transportation: Railway systems, tunnels, and electric vehicles (fire-resistant power and control cables for critical components).

• Chemical & Pharmaceutical: Laboratories, chemical processing facilities, and cleanrooms (halogen-free, chemical-resistant, and fire-safe requirements).
