Choosing the Right Industrial Cables for Your Application
Selecting the right industrial cable for your specific application is a critical decision that impacts system reliability, safety, operational efficiency, and long-term costs. With thousands of cable types and specifications available, the selection process can be overwhelming. This comprehensive guide from Newtek Kabel's engineering team will help you navigate the key considerations and make informed choices for your industrial cabling needs.
Understanding Your Application Requirements
Before selecting a cable, you must thoroughly understand the specific demands of your application. This analysis forms the foundation for all subsequent selection decisions.
Key Application Parameters
- Signal Type and Voltage: What signals will the cable carry (power, control, data)? What voltage levels are required?
- Current Requirements: What is the maximum current that needs to be carried? What is the typical operating current?
- Transmission Distance: How far does the signal need to travel? Longer distances may require specialized cables to prevent signal degradation.
- Bandwidth/Data Rate: For communication and data cables, what bandwidth or data rate is required for your application?
- Installation Environment: Will the cable be installed indoors or outdoors? Fixed installation or flexible/moving application?
Environmental Considerations
Environmental factors significantly influence cable performance and longevity. Cables must be specifically designed to withstand the conditions they'll be exposed to throughout their service life.
Critical Environmental Factors
Temperature Extremes
Cables must withstand both the minimum and maximum temperatures they'll encounter. Standard PVC insulated cables typically operate between -15°C to +70°C, while specialty cables can function in ranges from -65°C to +250°C depending on the materials used. Temperature cycling (repeated heating and cooling) can be particularly challenging and requires specialized construction.
Chemical Exposure
Industrial environments often contain oils, solvents, acids, or other chemicals that can degrade standard cable jacketing. For these applications, specialized materials like TPE, TPU, or fluoropolymers may be required to ensure chemical resistance and longevity.
UV and Weather Exposure
Outdoor installations require cables with UV-resistant jacketing to prevent degradation from sunlight. Weather-resistant cables must also withstand moisture, rain, and temperature variations without compromising performance.
Mechanical Stress
Applications involving movement require cables specifically designed for dynamic use. Consider factors like bend radius, flexing cycles, abrasion resistance, and tensile strength based on the installation environment and operational demands.
Common Industrial Cable Types and Their Applications
Understanding the various types of industrial cables and their typical applications can help narrow down your selection. Here are the most common categories used across industries:
Power Cables
Designed to carry electrical power from one point to another, with construction focused on current-carrying capacity and insulation suitable for the voltage level.
- Low Voltage: Up to 1kV, used for general power distribution
- Medium Voltage: 1kV to 36kV, used in industrial power networks
- High Voltage: Above 36kV, used for transmission lines
Control Cables
Used for transmitting control signals rather than power, typically at lower voltages. These often feature multiple cores for different control functions.
- Automation systems and PLCs
- Machine control and instrumentation
- Safety circuits and monitoring systems
Data and Communication Cables
Specialized for transmitting data with minimal loss or interference. Design focuses on maintaining signal integrity.
- Ethernet/Cat Cables: For network communications
- Fieldbus Cables: For industrial network protocols
- Fiber Optic: For high-speed data and long distances
Specialty Cables
Designed for specific challenging applications or environments that standard cables cannot handle.
- High-Temp Cables: For furnaces, kilns, and hot processes
- Chemical-Resistant: For chemical processing environments
- Continuous Flex: For robotics and constant movement
Key Technical Specifications to Consider
When evaluating industrial cables, these technical specifications will determine suitability for your application:
Electrical Specifications
- Conductor Material and Size: Typically copper or aluminum, sized according to current requirements (AWG or mm²)
- Voltage Rating: Maximum operating voltage the cable is designed to handle safely
- Impedance: Critical for data cables to match system requirements
- EMI/RFI Protection: Shielding requirements for electromagnetic interference
Mechanical Specifications
- Minimum Bend Radius: How sharply the cable can be bent without damage
- Tensile Strength: Maximum pulling force during installation
- Flex Life: Number of flex cycles for dynamic applications
Industry-Specific Cable Selection Guide
Different industries have unique requirements for their cable infrastructure. Here's a quick reference guide for some key industrial sectors:

- Extreme weather-resistant for wind turbines
- Torsion-resistant cables for rotating applications
- Long service life cables for difficult-to-access areas
Regulatory Compliance and Standards
Industrial cables must comply with various national and international standards depending on the application and installation location. Key standards to be aware of include:
- UL/CSA Standards: Required for North American installations, covering safety, flame resistance, and application suitability
- IEC Standards: International standards covering electrical, mechanical, and environmental performance
- ATEX/IECEx: For potentially explosive atmospheres in hazardous locations
- NFPA 70/NEC: National Electrical Code requirements for installations in the US
- Industry-Specific: Standards for marine, rail, mining, or other specialized sectors
Cable Selection Checklist
Use this checklist to ensure you've considered all critical factors when selecting industrial cables:
- Define the electrical requirements (voltage, current, signal type)
- Identify all environmental conditions the cable will be exposed to
- Determine mechanical stresses (static installation vs. dynamic movement)
- Check regulatory requirements and needed certifications
- Consider special requirements (fire resistance, low smoke, etc.)
- Evaluate installation considerations (pulling, termination, space constraints)
- Calculate total cost of ownership (material, installation, maintenance, replacement)
- Verify availability and lead times for critical projects
