Inorganic Mineral Insulating Electric-Heating Belt(MI Electricity-Heating Belt)

Inorganic mineral insulating electric heating tape
The electric heating tape is consist of successive, seamless metal sheath,one or several resistance heating core and compactedmagnesia insulation. F46 fuoroplastic or PVC sheath canbe added under the circumstance of strong corrosion.

Structure diagram

Inorganic mineral insulation heating element
The component of the imorganic mineral insulating heatconsists the middle part heating cable and the twoends,cold cable,and thecoupler.and terminal.and can beconnected with the electricity power easily.The heatingcomponents can be made in varous shapes inaccordancewith the using requirement, while the heating and coldcables can be connected by the coupler

Characteristics
convenlentuse
Thanks to the various sizes,the system can apply to any special feld,such as pump,concrete roads, asphalt roads cobblestone road
Saving energy
Cable capacitive reactance and inductive reactance is quite low, thus it has comparatively high power, which saves 30%% more energythan air conditioning instrument. t can be used under the temperature of 800’c, and its temperature-control precision can reach + 5C.Longevity
The cable materials intrinsic attributes guarantee the stability and longevity of the cable, it can be used over 40years under thenormal circumstance, which saves up maintaince and human resource of repainng.High mechanical strength
The cable is sturdy and durable, it can undergo violently mechanical damage without injuring the electrical function, it can normallywork even 1/3 of outer diameterhas distorted.
Infammability
The cable is made from inorganic material,which makessure that infammabilty or aid of flame.thus it can keep being used in the fire
without making any toxic gas.High and tightnessThe cable can completely immerse in the water due to the successively seamless metal jacket or used in vacuum, pressure places .ltsolves the problem of crossing-wall at the same time.
Safty and reliablility
The system can be more safe and reliable by cable high insulation, high impermeability and comprehensive protection.

Executive standard
Heating cable which maximum heating temperature under 250’c implements the standard lEC60800-2009. The heating cable which temperature over 250C,implements enterprise standard

Product inspection parameter
Length:+ 10%
Electrical performance
Tolerance ofresistance: +10%
Dielectric property:
Heating cable test: 1500VAC 1 min
Voltage withstand ofheating component: 1200VAC/1 minInsulation resistance:
Fiished product inspection:100M0/500VDCContmity of sheath:
Immerse the completed cable (including connection) in water for 12 hours, and then measure the insulation resistance, the value
should be not less than 1000/500VDC.In order to correctly choose the heating cable and its component meeting the requirement, we must verify the load and choosesuitable wire core materal. Calculate wire core resistance, determine thematenal of jacket considening the variation of resistance withtemperature.
