1.JMI加熱電纜概述 Brief Description JMI 加熱電纜是一種以不銹鋼作為外護(hù)套、電熱材料作為發(fā)熱元件、氧化鎂粉作為絕緣的特殊加熱電纜。 JMI 加熱電纜發(fā)熱量與工作電壓、發(fā)熱芯線和電纜長度有關(guān)。加熱電纜具有耐高溫、防水、防爆、不易老化、使用壽命長、機(jī)械強(qiáng)度高和安全等特點(diǎn)。 JMI heating cable is a special heating cable with a kind of metal as outer jacket and a kind of electric heating material as heating elememt and with magnesia powder as insulation. The quantity of heat is related to working voltage, the length of core wire and cable. They have following characteristics: high temperature resistance, water-proof, explosion proof, anti-aging, high mechanical strength and safety and reliability. 2.型號含義 Type Meaning 3.單芯兩端引接線接線方式 Two-end Leading wire of single core 4.不銹鋼護(hù)套JMI加熱電纜技術(shù)參數(shù) Technical Parameters of JMI Heating Cable with Nickel Chromium Heating core,Stainless Steel Jacket 型號 線徑 mm 護(hù)套外徑 mm 20℃芯 線阻值 MΩ/hm 經(jīng)濟(jì)耐用 短長度 m 較大載 流量 A 較大米 功率 w/m 較高使 用溫度 ℃ 耐壓試驗(yàn) V/5min 近似重量 kg/km 220V 380V JMI-I 01 0.76 3.00 2.40 18 32 5.0 60 700 1100 42 02 0.95 3.00 1.55 19 32 7.6 90 750 1500 42 03 1.07 3.2 1.17 19 32 9.8 113 750 2500 49 JMI-II 01 0.71 2.80 1.2 28 48 6.6 53 700 1500 38 02 0.95 3.00 0.68 35 61 9.1 57 700 1500 42 03 1.13 3.2 0.48 41 71 11.2 60 700 1500 49 04 1.38 3.5 0.32 48 83 14.4 66 750 1500 62 JMI-III 01 0.71 2.8 0.575 40 69 9.6 53 700 1500 38 02 0.95 3.0 0.330 51 88 13.1 57 700 1500 42 03 1.13 3.2 0.230 59 102 16.2 60 700 1500 49 04 1.38 3.5 0.150 70 121 21 66 750 1500 62 JMI-III 01 0.71 2.8 0.171 84 145 15.3 40 700 1500 38 02 0.95 3.0 0.098 99 171 22.6 50 700 1500 42 03 1.13 3.2 0.0684 109 188 29.6 60 700 1500 49 04 1.38 3.5 0.0456 128 221 37.8 65 750 1500 62 05 1.78 4.0 0.02736 159 275 50.6 50.6 750 1500
