江蘇春晨電纜有限公司生產(chǎn)JXN電機(jī)引接線， Metal shielding effect: 1）形成工作電場(chǎng)的低壓電極，當(dāng)局部有毛刺時(shí)也會(huì)形成電場(chǎng)強(qiáng)度很大的情況，因此，也要力圖使導(dǎo)體表面盡量做到光滑圓整無毛刺。 1) to form a working electric field of low voltage electrode, when the local burr will form a large electric field strength, therefore, we should try to make the conductor surface as smooth as possible without burr. 2）提供電容電流及故障電流的通路，因此也有一定的截面要求。 2) to provide the capacitive current and fault current path, so there is a certain section requirements. 半導(dǎo)電屏蔽層 Semi conductive shield 半導(dǎo)電屏蔽層是中高壓電纜采用的一項(xiàng)改善金屬電極表面電場(chǎng)分布，同時(shí)提高絕緣表面耐電強(qiáng)度的重要技術(shù)措施。 Semi conductive shielding layer is an important technical measure to improve the electric field distribution on the surface of the metal electrode, and to improve the electrical resistance of the insulation surface. 1）首先代替導(dǎo)體形成了光滑園整的表面，大大改善了表面電場(chǎng)分布， 1) firstly, the surface of smooth surface is formed by replacing the conductor, which greatly improves the surface electric field distribution, 2）同時(shí)，能與絕緣緊密接觸，克服了絕緣與金屬無法緊密接觸而產(chǎn)生氣隙的弱點(diǎn)，而把氣隙屏蔽在工作場(chǎng)強(qiáng)之外。在附件制作中也普遍采用這一技術(shù)。 2) at the same time, it can be closely contacted with the insulation, which overcomes the weakness that the insulation and the metal can not close contact with the air gap, and the air gap shield is outside the working field strength. This technology is widely used in the production of accessories. 絕緣 insulation 絕緣是將高壓電極與地電極隔離的關(guān)鍵結(jié)構(gòu)。 Insulation is the key structure of the high voltage electrode and the ground electrode. 1） 承受工作電壓及各種過電壓長期作用，因此其耐電強(qiáng)度及長期穩(wěn)定性能 是整個(gè)電纜完成輸電任務(wù)的重要部分。 1) to withstand the working voltage and a variety of overvoltage and long-term effect, so its electrical strength and long-term stability is the most important part of the whole cable to ensure the completion of the transmission task. 2） 能耐受發(fā)熱導(dǎo)體的熱作用而保持應(yīng)有的耐電強(qiáng)度。 2) can withstand the thermal effect of the heating conductor and maintain the electrical strength. JXN電機(jī)引接線 電纜技術(shù)的進(jìn)步主要由絕緣技術(shù)的進(jìn)步所決定。從生產(chǎn)到運(yùn)行，絕大部分試驗(yàn)測(cè)量項(xiàng)目都是針對(duì)監(jiān)測(cè)絕緣的各種性能為目的的。 The progress of cable technology is mainly determined by the progress of insulation technology. From production to operation, the vast majority of test items are for the purpose of monitoring the performance of insulation for the purpose of. JXN電機(jī)引接線 護(hù)層 Protective layer 護(hù)層是保護(hù)絕緣和整個(gè)電纜正常工作的重要。 Protective layer is an important guarantee for the protection of the normal and reliable work of insulation and the whole cable. JXN電機(jī)引接線 針對(duì)各種環(huán)境使用條件設(shè)計(jì)有相應(yīng)的護(hù)層結(jié)構(gòu)。主要是機(jī)械保護(hù)（縱向、徑向的外力作用），防水、防火、防腐蝕、防生物等?？梢愿鶕?jù)需要進(jìn)行各種組合 In view of various environmental conditions, the design of the corresponding protective layer structure.
