Constant-power heating cables provide constant heating power per meter, regardless of temperature. This type of heating cable has separate conductors for current-carrying and heat-producing components. These heating cables can be cut to desired lengths, but cold ends will form at the contact points located every meter, depending on the cut point.

Constant wattage heating cables are most commonly used in applications requiring temperatures greater than 100°C. They are manufactured with insulation materials such as FEB, PTFE, and PFA to withstand temperatures up to 260°C.

Constant wattage heating cables must be controlled by a temperature control system to ensure longevity of the system, otherwise overheating may occur.

Fixed Power Cables with EHT Engineering

Safe and Uninterrupted Heating Solutions at High Temperatures

Temperature control in industrial facilities is critical for process safety and energy efficiency. Standard heating systems can be inadequate, especially in applications requiring high temperatures. Constant Wattage Heating Cables come into play at this point, ensuring process continuity and safety by providing constant wattage heating throughout each meter. At EHT Engineering, we offer industry-specific solutions in the sales and installation of constant power cables, drawing on nearly 30 years of experience.

 What is a Fixed Power Cable?

A fixed power cable is a type of electrically operated heating cable. Their most distinctive feature is that each meter of cable generates a constant amount of heat, regardless of temperature. The current-carrying and heat-producing sections are made of different conductors. This structure ensures uniform heat distribution, even over long runs.

Fixed power cables are generally:

• In processes requiring high temperatures
• In anti-freeze systems
• In tanks and pipelines
• In chemical plants
• In food and pharmaceutical production areas
• In hazardous areas (Ex-Proof areas)

As EHT Engineering, we supply these cables in custom sizes and technical specifications.

Technical Specifications

Fixed power cables are manufactured to withstand harsh environmental conditions. EHT Engineering offers the following products:

Thanks to these features, fixed power cables offer a heating solution that is both safe and long-lasting.

Intelligent Temperature Control

Because fixed power cables operate at constant power, they are recommended for use with temperature control systems. At EHT Engineering, we offer the following solutions:

• Compatible with digital and analog thermostats
• Systems that are automatically activated according to the ambient temperature
• Overheating protection
• Remote control from mobile devices
• Integration with SCADA and PLC systems

Thanks to these systems, energy consumption is optimized and the life of the cable is extended.

Application Areas

Fixed power cables can be used in a wide variety of industries. At EHT Engineering, we offer specialized solutions for the following areas:

• Petrochemical and refinery facilities: Freezing and viscosity control in pipelines operating at high temperatures
• Food production facilities: Maintaining the fluidity of substances such as glucose, honey, oil
• Pharmaceutical industry: Keeping liquid raw materials at stable temperature
• Power plants: Temperature management in steam lines
• Chemical plants: Process temperature control in reactors and tanks
• Dangerous areas: ATEX compatible cable applications in Ex-Proof areas

Special cable selection, length planning and control system integration are done for each application.

Flexible Design and Cuttability

Fixed power cables can be cut to desired lengths. However, this process must be done at the contact points located every meter of the cable. Otherwise, cold ends may occur. As EHT Engineering:

• We do project-based length planning
• We provide ease of installation by marking the cutting points.
• We offer special termination kits to prevent cold ends

In this way, efficient and safe operation of the system is guaranteed.

Energy Efficiency and Sustainability

Constant power cables make energy consumption predictable due to their constant wattage output. As EHT Engineering:

• We offer cables with high efficiency insulation materials
• We prevent unnecessary energy consumption with temperature control systems.
• We reduce resource consumption with long-lasting products
• We minimize environmental impact with recyclable materials

This approach contributes to both nature and business budgets.

Installation and Technical Support

As EHT Engineering, we offer turnkey services for fixed power cables:

• On-site discovery and needs analysis
• Project-based engineering design
• Product supply and assembly
• Testing and commissioning
• User training and technical documentation
