Due to the equipment in the environment and temperature requirements are different, so the use of electric accompanied by tropical is not the same, such as self-limiting temperature accompanied by tropical, constant power electric accompanied by tropical, but in some special high-temperature places and steam blowing pipeline ordinary electric accompanied by tropical can not meet the requirements, this time you need to use the MI armored heating cables, which are made of metal materials, temperature-resistant temperature can be up to 800° ° C high temperature.

                       Then for MI heating cable in high temperature occasions with heat what are the preparatory matters?
　　              1, need to check MI armored heating cable specifications, model is not in line with the requirements.
　　              2, check the appearance of MI armored heating cable, ensure that the heating cable is intact, no damage, there is the length is not and the length of the label is - the same.
　　              3, MI armored heating cable and ordinary cable is the same, insulation resistance test is very important, so the need for MI heating cable insulation resistance test.
　　           4, if the MI armored heating cable has damage or other problems, you can carry out AC voltage withstand test on the heating cable.
　　           5, for some small cross-section MI cable or multi-core MI cable, should also carry out the test of the continuity of the cable conductor, found that the broken wire should promptly notify the supplier or manufacturer to deal with.
　　           6, due to MI armored heating cable insulator for magnesium oxide, and magnesium oxide moisture-absorbing capacity is particularly strong, so special attention must be paid to avoid touching the outer sheath of the cable, and for the cable segments and cable end sealing damage must be promptly re-sealed.
