Composite insulator Overall bar type design, compact structure, high quality, weight is 1/10 of the same grade porcelain and glass insulators, extremely convenient transportation, and installation. It is suitable for fouling areas, high mechanical tensile load, large span, and compact lines. The foul flash voltage is 30%-50% higher than that of porc...
Research shows that the heat generation of power line insulators consists of three parts.One is the heat generated by the polarization effect of the dielectric excited under the action of the working frequency voltage.Second, the internal penetrating leakage current heating.The third is the surface creepage leakage current heat generation.?W...
In this article, we continue to introduce how to install the cable joints3. Insulation shielding treatment: To ensure the contact between the insulation shielding layer and the shielding layer inside the preform, the insulation shielding layer shall be extended. The common methods are coating semi-conductive paint and molding semi-conductiv...
Integral prefabricated joints are by far the most common type of cross-linked cable joints. The factor that has the greatest impact on the quality of the joint during field installation is the site-specific installation tools. The quality of prefabricated parts should be completed in the factory with electrical tests and reliable quality. According to...
EPDM material and silicone rubber material are two kinds of raw materials that are widely used in cable termination accessories at this stage. They each have their own advantages and disadvantages and are applicable in different ranges, contributing their share to the development of transmission and distribution. The Advantages of Cable Termin...
