一、執行標準： JB6213 92 Q／12YJ 4135-2000 二、適用范圍： 適用于交流額定電壓6000V及以下的電機繞組的引出連接用。 三、使用特性： 電線導體的長期允許工作溫度應不超過70℃。具有良好的柔軟性及耐熱、耐溶劑性 Letter we do not understand the purchase of heating cable, in the Chinese cable industry network to share some knowledge of heating cable to buy, simple and easy to understand and easy to operate, for your reference.   一、看外觀光滑與平整;先不說電纜上有規格、型號、電阻等，字要是機器噴上去的，會有類似盲文一樣的暗紋。 Look, a smooth appearance and smooth; I will not speak with specificationtype resistance cable, if the word machine sprayed up, there will be similar to the same dark lines in braille.   二、看結構上由內到外有：碳纖維絲(24k或12k)--F46鐵氟龍--聚氯乙烯pvc護套。 Two, the structure from the inside to the outside are: carbon fibers (24K or 12K) --F46 Teflon - PVC sheath.   三、看接頭，這也是發熱線纜的一個技術難點。目前進口電纜中已注塑一次成型的接頭為主，技術成熟，可靠性好，所以穩定性和耐水性等相對提高了。JEH電機引接線 Three, look at the joint, which is a technical difficulty of heating cable. At present, the import cable has been injection molding of a joint based, mature technology, good reliability, so the stability and water resistance, and so on.   發熱電纜以后再生活中會變得越來越常見，所以大家有必要了解發熱電纜的選購。 JEH電機引接線 Heating cable will become more and more common in life, so it is necessary to understand the purchase of heating cable.   JEH電機引接線
