Self-regulating heating belt with terminal box

A self-regulating heating belt with a terminal box provides energy-efficient, safe, and flexible heat tracing for pipes, tanks, and industrial equipment.Self-Regulating Heating BeltsSelf-regulating heating belts, also known as self-limiting heating cables, automatically adjust their heat output based on the surrounding temperature. They consist of a conductive polymer core with PTC (Positive Temperature Coefficient) characteristics, covered by an insulating sheath. This design allows the cable to increase heat output in colder areas and reduce it in warmer areas, ensuring consistent temperature control and energy efficiency . Key features include:Operating temperature range: minimum -40°C, maintaining 65–135±5°C for industrial applications .Output power options: 10, 15, 25, 35, 45 W/m at 10°C .Flexible and easy to install, with bending radius of 12.7 mm at 20°C and 35 mm at -30°C .Suitable for freeze protection, process pipelines, storage tanks, valves, and hazardous or corrosive areas .Can be cut or extended within a certain range without affecting performance .Terminal Boxes for Self-Regulating Heating CablesTerminal or junction boxes are used to connect self-regulating heating cables to the power supply and to branch multiple cables. They are designed to protect connections from moisture, dust, and corrosion, and are often rated for hazardous areas. Common features include:IP66 to IP69K protection against dust, water, and high-pressure cleaning .Capacity to connect multiple cables: typically up to three heating cables for power input and three for branching .Terminal blocks compatible with single-core or multi-core wires, cross-section 1.5–10 mm² .Mounting options: wall, pipe, or bracket installation, including insulated pipes up to 50 mm thick .Materials: fiberglass-reinforced polyamide or corrosion-resistant metals, UV-resistant and non-flammable .Explosion-proof versions available for hazardous locations, certified for use with specific self-regulating cables .Installation and CompatibilityTerminal boxes are compatible with a wide range of self-regulating cables such as HTM, HTA, HTP, BTC, BTX, CTE, and Protrace series .Cable glands accommodate unarmored cables (7–18 mm) or armored cables (12–20 mm) depending on the box design .Boxes may feature screw or push-in terminals, and some designs allow snap-on mounting to pipe brackets for quick installation .Critical components like metal pipe straps, cable entry units, and flexible sealed glands may need to be ordered separately .ApplicationsSelf-regulating heating belts with terminal boxes are widely used for:Industrial pipe and tank freeze protection.Maintaining process temperatures in chemical, oil, and food industries.Residential frost protection for water pipes and storage tanks.Hazardous or corrosive environments requiring explosion-proof connections . These systems provide reliable, energy-efficient heating with minimal maintenance, making them suitable for both industrial and residential applications.
