Order Longline Heating Cables (3 Phase) |Built for Harsh Conditions

Buy Longline Heating Cables (3 Phase) for jobs that need more power and longer runs than single-phase cables can handle. Our three-phase cables spread power across three conductors so each one carries less current, which cuts voltage drop and lets you run farther without extra feed points. We use strong insulation and durable outer jackets so the cable keeps working in sun, rain, or rough handling.

Our experts give clear sizing guidance, wiring details, and support for controllers and junctions boxes so installers save time. We test every cable for electrical and heating performance, and we offer different wattages, lengths, and accessories to match your site. Our team works with you to pick the best cable and to make installation smooth and safe.

Here are some of the top Long Line Heating Cables we supply. 

Fixed-output 

We supply fixed-output longline cables to deliver the same watts per meter along the entire run. Our design gives steady, predictable heat for pipes, tanks, and process lines that need constant temperature control. Use them where you want uniform protection and where process temperatures stay stable.

• Constant wattage per meter for even heating
• Simple to size and specify for long runs
• Works well with standard thermostats or controllers
• Low-cost option for steady-state needs
• Good for freeze protection and viscosity control

FAQs

How do I terminate or splice a 3-phase longline cable?

You can do it by:

• Using approved junction and termination kits
• Following our step-by-step installation guide
• Making sure joints have proper sealing and strain relief We supply the kits and instructions to keep connections safe.

How should I maintain these heating cables? 

We advise regular visual checks, electrical tests for continuity and insulation resistance, and testing of control parts to keep the system reliable.

Why choose three-phase instead of single-phase?

You should pick them because:

• Three-phase splits power across three conductors
• Each conductor carries less current
• Lower current reduces voltage drop This helps you run longer cable lengths with fewer power feed points.

Can you help size the cable for my job? 

Yes! We size cables from run length, heat needed per meter, ambient conditions, and allowed voltage drop, then give charts and recommendations so installers pick the right cable.

Can I buy them for outdoor use?

Yes, you can use them anywhere as we:

• Use UV-stable jackets
• Add moisture-resistant insulation when needed
• Offer armored options for extra protection 

These choices keep the cable safe outdoors.
