The existing IEC doesn’t succficiently reveal the potential adhesion problems in polymeric line insulators.
Algeria, a country covering 2,381,741 square km in Africa, and the largest nation in Africa too, is seeking the opportunity of development in the electricity industry. With the rapid growth of demand for electricity, some merchants smell the potential fortune in self-supplying electrical components, such as high voltage polymeric insulators. In recent years, more and […]
Insulators are important items in electrical power lines, they are widely used in all circuits and electrical or electronic systems to isolate electricity between two conductive materials. What we talk about today are polymer insulators and porcelain insulators applied on high voltage overhead lines. What’s the difference between polymer insulators and porcelain insulators? First of […]
Our company has started cooperation with LS electron ltd on smart meters. These include smart power meters and smart water meters. The most significant feature of these new products is that both smart power meters and water meters are embedded with IoT (Internet of Things) technology. This modern technology helps users to save time and […]
Solar Photovoltaic Monitoring System is now online in our product list. This monitoring system collects data from inverters of solar panel array and transfers data via a self-built wireless network. It cut the cost of installation and maintenance as no telecom network is needed.
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 […]
With the world’s recovery from COVID-19 epidemic situation, manufacturers of composite insulators become active again. The first batch of upgraded polymer insulator crimping machines is about to go overseas to India Hyderabad. In the first half of this year, we have been dedicated to R&D of new appearance and optimized function of current testing machines […]
Different housings are available these days for the external insulation of EHV and UHV bushings. These include: porcelain, which may or may not also be coated with RTV silicone material to improve pollution performance; hybrid housings consisting of a porcelain core with a polymeric housing; and a composite housing based on an internal FRP tube […]
What is HIPOT test? A Hipot test is a test for insulation. Its full name is high potential test, which actually means dielectric withstand test. Why should we do the hipot test? Hipot test is an important test, it helps users to identify the peek withstand value of insulation, and discrepancy of insulation material. In […]
The thermal-mechanical test is one of the most significant tests for composite insulators. Here we have a partial section of International Standard IEC 61109 2008: Insulators for overhead lines – Composite suspension and tension insulators for a.c. systems with a nominal voltage greater than 1 000 V – Definitions, test methods, and acceptance criteria. IEC […]
