In industrial environments such as oil refineries, chemical plants, coal mines, and pharmaceutical workshops, where flammable gases, vapors, dust, or fibers may exist, explosion-proof industrial cables are critical components that ensure safe and stable operation of electrical systems. Unlike ordinary industrial cables, they are specifically designed to prevent the risk of explosions caused by electrical faults. Understanding their key features is essential for selecting the right cables to mitigate potential hazards and maintain operational reliability.
The core feature of explosion-proof industrial cables lies in their structural design that contains and isolates potential ignition sources. One of the key structural elements is the armored layer. Typically made of double-layer steel tape or steel wire, this layer not only enhances the cable’s mechanical strength to resist external impacts, abrasions, and crushing but also acts as a barrier to prevent sparks or high temperatures generated inside the cable from escaping into the surrounding explosive atmosphere. Additionally, the sealing structure at cable joints and terminations is crucial. High-quality explosion-proof cables adopt flame-retardant and pressure-resistant sealing materials, such as nitrile rubber or silicone rubber, to ensure that no flammable substances enter the cable interior and no hazardous substances leak out, meeting strict IP (Ingress Protection) ratings like IP66 or IP68.
The insulation and sheath materials of explosion-proof industrial cables are carefully selected to withstand extreme temperatures and resist combustion. Common insulation materials include cross-linked polyethylene (XLPE) and ethylene propylene diene monomer (EPDM), which exhibit excellent heat resistance, chemical stability, and electrical insulation performance. They can operate normally in high-temperature environments (often ranging from -40°C to 125°C, or even higher for special grades) without melting or decomposing. The sheath is usually made of chlorinated polyethylene (CPE) or polyvinyl chloride (PVC) with flame-retardant additives, which not only prevents the cable from catching fire easily but also inhibits the spread of flames and the release of toxic smoke when exposed to fire, complying with international standards such as IEC 60332-3 for flame propagation.
Industrial environments are often filled with electromagnetic interference (EMI) from motors, frequency converters, and other electrical equipment. Explosion-proof industrial cables are equipped with effective shielding layers to minimize the impact of EMI on signal transmission and prevent the cable itself from emitting electromagnetic radiation that could interfere with other devices. Common shielding structures include tinned copper mesh, aluminum foil, or a combination of both. For example, a copper mesh shielding layer with high coverage (over 90%) can effectively block high-frequency interference, while aluminum foil shielding is suitable for low-frequency interference. This shielding feature is particularly important for control cables and signal cables used in explosion-proof areas, ensuring accurate and stable data transmission.
In chemical plants, oil and gas fields, and other settings, cables are often exposed to corrosive substances such as acids, alkalis, oils, and solvents. Explosion-proof industrial cables are designed with chemical-resistant materials that can resist the erosion of these substances. For instance, cables with fluoropolymer (such as PTFE) insulation and sheath have superior chemical resistance, maintaining their performance even when in contact with strong acids or organic solvents for long periods. This chemical resistance ensures the cable’s service life and prevents insulation or sheath damage that could lead to electrical faults and explosion risks.
Genuine explosion-proof industrial cables must comply with strict international and regional safety standards to guarantee their reliability. Common standards include IEC 60079 (International Electrotechnical Commission standards for explosive atmospheres), ATEX (European Union directives for equipment and protective systems intended for use in potentially explosive atmospheres), and UL 913 (Underwriters Laboratories standard for intrinsically safe equipment and associated apparatus for use in Class I, II, III, Division 1 hazardous locations). Compliance with these standards means the cables have undergone rigorous testing, such as flame resistance, explosion containment, and temperature cycling tests, ensuring they can be safely used in designated hazardous areas.
