Heating Cable for Industrial Thermal Tracing

Product Specifications

Technical details and manufacturing context for Heating Cable

Definition

A heating cable is a specialized electrical component used within thermal tracing systems to maintain process temperatures, prevent freezing, or control viscosity in industrial piping, vessels, and equipment. It converts electrical energy into heat through resistive elements, typically using a nickel-chromium alloy heating wire. The generated heat is transferred to the pipe or surface via conduction, with temperature regulation achieved either by external controllers or through self-regulating properties inherent to the cable design.

Constructed with fluoropolymer insulation, a copper braid shield, and a polyolefin outer jacket, the cable is designed for durability in demanding environments. Key parameters include a rated voltage of 220–240 V AC (IEC 60800), power output ranging from 10 to 60 W/m depending on heat loss and pipe size, and a maximum continuous temperature of 65–150 °C (IEC 60800). The minimum installation temperature is -40 °C, below which the cable may crack. Insulation resistance is at least 20 MΩ at 20 °C after water immersion (IEC 60800), and dielectric strength withstands 2500 V AC for 1 minute without breakdown. Conductor resistance tolerance is ±10% (IEC 60228), ensuring consistent heat output. The outer sheath material is FEP/PFA for chemical and moisture resistance, and the IP rating is IP67–IP68 for wet or submerged installations. The bending radius should be 5–10 times the outer diameter to avoid damage, with cable diameters of 6–12 mm and weight of 0.1–0.3 kg/m.

When selecting a heating cable, verify model-specific values and standards with the legal manufacturer or supplier, as the listed parameters are reference ranges. Confirm compatibility with the intended application, including pipe size, heat loss calculations, and environmental conditions. Regular inspection for insulation resistance and physical damage is recommended to ensure reliable operation.

Working Principle

Electrical current flows through resistive heating elements within the cable, generating heat through Joule heating (I²R effect). The heat is then transferred to the pipe or surface through conduction, with temperature typically regulated by external controllers or self-regulating properties.

Frequently Asked Questions

What is the typical power output range for a heating cable?

The power output typically ranges from 10 to 60 W/m, depending on heat loss and pipe size. The exact value must be selected based on the specific application and verified with the manufacturer.

What is the maximum continuous temperature the cable can withstand?

The maximum continuous temperature is 65–150 °C, as per IEC 60800. For higher temperatures, special applications may require cables with different specifications, so always confirm with the supplier.

Can the heating cable be used in wet or submerged installations?

Yes, the cable has an IP rating of IP67–IP68, making it suitable for wet or submerged installations. However, ensure that the installation conditions match the cable's specifications and that all connections are properly sealed.

What is the minimum installation temperature?

The minimum installation temperature is -40 °C. Below this temperature, the cable may crack, so installation should be avoided in such conditions unless the manufacturer provides specific guidance.
