CALEDONIAN HEATING CABLE
CC-SC serial-connection type electric heating belt
Product Description
CC-SC serial-connection type electric heating belt is a new type heating product. Compared with other heating belts, its most character is its working length is the longest, about 5-12 times longer than that of general constant-power or self-controlled type electric heating belts. So it is specially suitable for long pipeline, large-size groove and oil tank to prevent frostbite, preserve heat and trace heat in petroleum, chemical industry, electric power, dock and so on. It may be used in Ⅱ-type explosion-proof gas condition if matched with other explosion-proof fittings.

Working Principle
Known from Joules Law, current releases energy constantly thorough conductor and forms one continuous, even heating belt.
Structure Format
A type is composed by three independent heating belts of the same power and the same length.
B type is composed by three insulated electric heating belts connected in parallel.
The insulation jacket and external insulation jacket of CC-SC serial-connection type heating belt are made from F46 or F4; while core line is special-type heating equipment.
Installation Instruction
(1) Do not drag the heating belt on ground when paving.
(2) As for sharp edge during installation, polish it or cover with aluminum adhesive tape to prevent insulation layer from being broken.
(3) During bending installation, the minimum bending radius can not be less that five times of thickness.
(4) Use aluminum adhesive belt to stick the heating belt during installation, for one hand, it increases dissipation area, which is good for thermal conductivity; for the other hand, it is convenient to install. Use stationary adhesive tape to fasten them every 50-80cm in radial direction after paving.
(5) Serial-connection type electric heating belt is usually designed according to detailed length. So the length is designed strictly during installation. If it is too long or too short, the power is influenced. So it is not permitted to cut as you please.
(6) Serial-connection type electric heating belt is installed according to Y connection. In order to avoid three-phase current error, it is better to earth in the end.
(7) As overload, short circuit, creepage protection and temperature control device are equipped in control cabinet, the quality of electric heating belt is warranted.
(8) If electric heating belt is buried underground or there is corrosive gas around, it is supposed to use strengthened type. |
