Constant Wattage Heat Tracing Cables
Constant Wattage Heat Tracing Cables
Constant wattage heat tracing cables are engineered to deliver reliable freeze protection and precise process temperature maintenance. Available in parallel (CWPHT) and series (CWSHT) configurations, these cables feature polymer insulation, nickel alloy heating elements, and robust outer braiding to maintain uniform power output across long pipelines and industrial vessels.
Constant Wattage Heat Tracing Cables
Constant wattage heat tracing cables are engineered for precise temperature maintenance and freeze protection. Available in Parallel (CWPHT) and Series (CWSHT) configurations, these cables provide constant power output per unit length. Parallel cables feature #12AWG polymer insulated bus wires and nickel alloy heating elements that remain operational even if a section fails, while series cables are optimized for long pipeline runs up to 3 KM.
Key Features & Capabilities
- Parallel Circuit Reliability: Parallel arrangement preserves system integrity—if any cable section fails, the remainder continues to operate seamlessly.
- Robust Construction: Built with #12AWG polymer insulated parallel bus wires, nickel alloy heating element wire, and durable polymer jacketing.
- High Braid Coverage: Provides over 85% braiding covering area for superior mechanical protection and earthing.
- High Thermal Limits: Operates at continuous surface temperatures up to 200°C with maximum exposure tolerance up to 230°C.
- Long Pipeline Performance: Series resistance options support circuit lengths up to 3 KM with equal heat distribution throughout.
