HCL series constant power electric heating cable is a new type of electric heating product. Compared with other electric heating cables, its major feature is its long use length. It is better than general constant power and self-limiting temperature electric heating cables. The larger use length is 5~12 times longer. Therefore, it is especially suitable for antifreeze, heat preservation and heat tracing of long-distance pipelines, large tanks, oil tanks, etc. in the petroleum, chemical, electric power, wharf and other industries. When matched with other explosion-proof accessories, it can be used in Class II anti-explosive gas occasions,220v RDP2-J3 parallel constant power electric heating cable. Example: HCL-A-660-30-3000 means a series electric heating cable with a voltage of 660V, a type A structure with a power of 30W per meter, and a total length of 3000m. HCL(Q)-B-380-40-800 represents a reinforced series electric heating cable with a voltage of 380V, a type B structure, a power of 40 meters per meter, and a total length of 800 meters.
① Heating core; ② Composite insulation layer; ③ Outer sheath; ④ Metal braided layer; ⑤ Reinforcement layer 4. HCL series constant power electric heating cable Working principle According to Joule's law, the current energized conductor continuously releases energy to form a continuous and uniform heating cable. 5. HCL series constant power electric heating cable Structure: Type A structure is composed of three independent electric heating cables with the same power and the same length; Type B structure consists of three electric heating cables that are insulated and arranged side by side; The insulating sheath and outer insulating sheath of HCL series electric tracing cable are both F46 or F4. The heating core is a special heating device, and the heating core is reinforced with copper braided outer sheath and inner insulating sheath. 6.HCL series constant power electric heating cable Installation instructions (1) The ground should not be dragged when discharging the heating cable; (2) When the electric tracing cable is installed with sharp edges, the sharp corners must be polished or lined with aluminum tape to prevent the insulation layer from being scratched; (3) When the electric tracing cable is bent and installed, its smaller bending radius should not be less than five times its thickness; (4) When installing the electric tracing cable, use aluminum tape to paste it, one is to increase the heat dissipation surface, which is conducive to heat conduction, and the other is to install it. After laying, fix it radially with fixing tape every 50-80cm; (5) Tandem electric heating cables are generally designed according to the actual length of the pipeline. Therefore, they should be installed strictly according to the designed length during installation. Too long or too short will affect the power, so arbitrary cutting is not allowed; (6) When installing a series electric heating cable, connect it according to Y. In order to avoid three-phase current error, the end must be grounded; (7) The electric heating cable control cabinet should have overload, short circuit, leakage protection and temperature control devices to ensure the quality of use; (8) The reinforced type should be used when the electric tracing cable is buried in the ground or is surrounded by corrosive gas.
