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

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

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.

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

Inconel 800	R	800℃

Item	Technical requirement
Convenient use	Thanks to the various sizes, the system can apply to any special field, 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 energy than air conditioning instrument. It can be used under the temperature of 800℃, and its temperature-control precision can reach ±5℃
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 repairing.
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 diameter has distorted.
Infammability	The cable is made from inorganic material,which makes sure that infammabilty or aid of flame. Thus it can keep being used in the fire without making any toxic gas.
High and tightness	The cable can completely immerse in the water due to the successively seamless metal jacket or used in vacuum, pressure places .lt solves 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.

Heating cable which maximum heating temperature under 250℃ implements the standard lEC60800-2009. The heating cable which temperature over 250℃, implements enterprise standard

Length:+ 10%
Electrical performance
Tolerance of resistance: +10%
Dielectric property:
Heating cable test: 1500VAC/1 min
Voltage withstand ofheating component: 1200VAC/1 min
Insulation resistance:
Finished product inspection:100MΩ/500VDC
Contmity 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 1000Ω/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 thematerial of jacket considering the variation of resistance with temperature.
