為大家介紹在電線電纜質量檢測的三大重要指標。
Introduce the three important indicators for wire and cable quality inspection.
一、絕緣電阻的測試
1、 Testing of insulation resistance
絕緣電阻式是反映電線電纜產品絕緣特性的重要指標，與耐電強度、介質損耗以及絕緣材料在工作條件下的逐漸劣化密切相關。
Insulation resistance is an important indicator reflecting the insulation characteristics of wire and cable products, closely related to electrical strength, dielectric loss, and the gradual deterioration of insulation materials under working conditions.
通過測量絕緣電阻，可以發現工藝中的缺陷，如絕緣干燥不透或護套損壞受潮；絕緣被污染，并混入導電雜質；各種原因引起的絕緣開裂等。電線電纜在運行中，經常要檢測絕緣電阻和泄漏電流，以此作為是否能夠繼續安全運行的主要依據。
By measuring insulation resistance, defects in the process can be found, such as insulation being dry and impermeable or the sheath being damaged and damp; The insulation is contaminated and mixed with conductive impurities; Insulation cracking caused by various reasons. During the operation of wires and cables, insulation resistance and leakage current are often tested as the main basis for whether they can continue to operate safely.
二、電容及損耗因數的測量
2、 Measurement of capacitance and loss factor
電纜加上交流電壓，就有電流流過。當電壓的幅值和頻率一定時，電容電流的大小與泥桿 保定古箏 塑料增韌劑 拱形護坡模具 保定空調維修  托輥生產線電纜的電容(Cx)成正比。對于超高壓電纜，該電容器的電流可能達到與額定電流可以相比的數值，這成為限制電纜容量和傳輸距離的重要因素。因此電纜的電容也是電纜的主要電性能參數之一。
By adding AC voltage to the cable, a current flows through it. When the amplitude and frequency of voltage are constant, the magnitude of capacitive current is proportional to the capacitance (Cx) of the cable. For ultra-high voltage cables, the current of the capacitor may reach a value comparable to the rated current, which becomes an important factor limiting cable capacity and transmission distance. Therefore, the capacitance of the cable is also one of the main electrical performance parameters of the cable.
