Intrinsically Safe Cables are specialized cables designed for use in areas where there is a risk of explosion or ignition, such as industrial plants, refineries, mines, and industrial automation applications. Their construction and materials are aimed at minimizing the risk of electrical sparks that could lead to an explosion.
Characteristics of Intrinsically Safe Cables:
-
Explosion Protection – Designed for use in explosive zones where dangerous gases, vapors, or dust may be present in the atmosphere.
-
Oil-Resistant Insulation – Made from PVC or PUR, ensuring resistance to oils, lubricants, and other chemicals, enhancing durability in tough industrial environments.
-
Numbered or Color-Coded Wires – Easier installation and identification of cables, improving work efficiency and reducing installation errors.
-
Shielding – These cables can be equipped with shielding to protect against electromagnetic interference (EMI), ensuring stable signal transmission.
-
Halogen-Free – Manufactured using halogen-free materials, meaning they do not emit harmful halogen gases in case of fire, improving safety.
-
Self-Extinguishing and Non-Propagating Flames – In case of contact with fire, these cables will not spread flames, contributing to increased safety in hazardous environments.
Their basic application is in areas where there is a risk of explosion. Another area of their application is in control and measurement technology in industrial automation systems. The outer sheath is oil-resistant, and the cable is protected with PVC and PUR insulation. They have numbered or colored conductors and are shielded so as not to disturb electromagnetic fields. For safety reasons, they are manufactured as halogen-free, self-extinguishing, and flame retardant.
Applications:
-
Chemical and Petrochemical Industry – Used for power and control of equipment in areas where explosive mixtures of gases or dust may be present.
-
Mines and Extractive Industry – Suitable for environments where there is a risk of methane or other flammable gases.
-
Automation Systems – Used in control and measurement systems that must operate safely in high-risk environments.
Intrinsically Safe Cables are crucial for ensuring safety in operations where the risk of explosion is high. Their construction ensures reliability and durability in difficult industrial conditions.
