Combined Electrical & Mechanical Test is an important test on high voltage porcelain disc insulators. In ANSI and IEC requirements, the disc insulator is mounted in a tensile testing machine with both ends connected. On the both ends, there is a voltage applied. This artical is embedded with a video of Combined Electrical & Mechanical […]
The definitions of insulators here refer to the circumscription of the electrical insulators on overhead power lines or high voltage power substations in standard IEC 60383-1:1993. Why should we clarify the definitions of insulators? Because in IEC 60383 standard, it describes each test, whether a mechanical or electrical test, that should be carried out. And […]
Bangladesh is a developing country in South Asia, a close neighbor of China, and a country with a growing demand for electricity in recent years. As a large quantity of electrical components is imported into Bangladesh for the construction of power lines, the test of these high voltage components becomes more and more vital. In […]
The electrical industry grows steadily in Pakistan with the rising demand of electricity. Not only for civil use, but also for industrial such as manufacturing, transportation, and etc. As a vital part of electrical overhead lines, high voltage insulators are largely required accordingly. In Pakistan, the majority of insulators are in porcelain material. These ceramic […]
Contune International Corporation has recovered full production capacity. With the effective control of the epidemic situation in China, most of the Chinese factories have re-opened and workers are gradually coming back to work. Back to 3 weeks ago, we have already done good preparation for this. And now, all the workers, engineers, management staff have […]
Composite insulator’s shed and sheath are be made of high temperature vulcanizing (HTV) type silicone rubber, having silicone polymer content by weight 30% minimum. Alumina Trihydrate (ATH) is used as a filler. The filler is properly mixed with silicone compounds to ensure uniform distribution. The thickness of the sheath shall be a minimum of 3 […]
