Why Certified Cables Matter in Hazardous Locations
In environments containing flammable gases, vapors, or combustible dust, standard industrial wiring is not sufficient. Improper cable selection can lead to:
-
Insulation breakdown
-
Spark generation
-
Gas migration through cable cores
-
System failure
-
Regulatory violations
Certified hazardous location cables are engineered to withstand harsh conditions while maintaining compliance with NEC, UL, ATEX, and IECEx standards.
When integrated with proper explosion proof enclosures and hazardous location cable glands, these cables form a fully compliant hazardous area electrical system.

Types of Hazardous Area Cables
Industrial hazardous locations require different cable constructions depending on environmental exposure and application type.
1. Armored Cables
Armored explosion proof cables provide mechanical protection against impact, vibration, and physical stress. These are commonly used in:
-
Oil & gas facilities
-
Offshore platforms
-
Petrochemical plants
-
Heavy industrial sites
When paired with certified cable glands, armored cables maintain explosion protection integrity.
2. Instrumentation Cables
Instrumentation cables are used for control signals, monitoring systems, and automation processes in classified environments.
These cables are designed to:
-
Minimize signal interference
-
Resist chemical exposure
-
Maintain insulation stability
-
Operate safely in hazardous zones
For intrinsic safety applications, instrumentation cables often work alongside intrinsic safety systems.

3. Power Cables for Hazardous Locations
Industrial power distribution in classified areas requires durable hazardous area power cables capable of handling high loads without compromising safety.
These cables must be:
-
Flame retardant
-
Heat resistant
-
Chemical resistant
-
Moisture resistant
They are commonly used with purge and pressurization systems and explosion proof control panels.
