江蘇春晨電纜有限公司生產(chǎn)JXN電機引接線， Metal shielding effect: 1）形成工作電場的低壓電極，當局部有毛刺時也會形成電場強度很大的情況，因此，也要力圖使導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. 半導電屏蔽層 Semi conductive shield 半導電屏蔽層是中高壓電纜采用的一項改善金屬電極表面電場分布，同時提高絕緣表面耐電強度的重要技術措施。 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）首先代替導體形成了光滑園整的表面，大大改善了表面電場分布， 1) firstly, the surface of smooth surface is formed by replacing the conductor, which greatly improves the surface electric field distribution, 2）同時，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，而把氣隙屏蔽在工作場強之外。在附件制作中也普遍采用這一技術。 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，因此其耐電強度及長期穩(wěn)定性能 是整個電纜完成輸電任務的重要部分。 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)熱導體的熱作用而保持應有的耐電強度。 2) can withstand the thermal effect of the heating conductor and maintain the electrical strength. JXN電機引接線 電纜技術的進步主要由絕緣技術的進步所決定。從生產(chǎn)到運行，絕大部分試驗測量項目都是針對監(jiān)測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電機引接線 護層 Protective layer 護層是保護絕緣和整個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電機引接線 針對各種環(huán)境使用條件設計有相應的護層結(jié)構(gòu)。主要是機械保護（縱向、徑向的外力作用），防水、防火、防腐蝕、防生物等。可以根據(jù)需要進行各種組合 In view of various environmental conditions, the design of the corresponding protective layer structure. Mainly mechanical protection (longitudinal, radial external action), waterproof, fire prevention, anti-corrosion, anti biological, etc.. Can be carried out according to the needs of a variety of combinations
