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 […]
Polymer insulators are important electrical items in electrical power overhead transmission, distribution, and substation lines. They provide reliable insulation between cables and iron towers, or between conductors and connecting fittings like clamps so that the electricity can be transmitted safely. With the global growth of the electrical industry, more and more people smell the potential […]
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 […]
What is a composite insulator? The composite insulator is also called the polymeric insulator. It is developed after toughened glass insulator and ceramic insulators, whose main insulation structure is consists of a fiberglass core (rod) and silicon housing and sheds. One both sides, 2 metallic fittings are installed on each side with crimping technics. These […]
With the quick spread of the epidemic situation of new coronavirus COVID-19, we know that not only China but also the entire world is now in great demand of face masks. So, to help more foreign manufacturers find the way to purchase the production line of coronavirus from China and begin manufacturing masks in their […]
Early since January 2020, the new type of coronavirus has shown up in China and it is now spreading to a wider range. Without strict control and official recommendation of “stay at home” to the mass majority of people, this coronavirus may have affected more people can cause a bigger loss. Now China government has […]
Africa has been dreaming about establishing its own factory of high voltage polymeric insulators since long ago, and this year their dream come true. The first manufacturer of 33kV silicon rubber insulator (polymeric insulator) is now moving its pace steadily to real production. This is not only a start but also a milestone for Tanzanian […]
Contune International Corp will attend the electrical expo in Jakarta, Indonesia from 11th to 14th.August 2019. The 3 days exhibition will hold hundreds of manufacturers in electrical field. For us, we will show our test machines for HV insulators there as well as production line of insulators. For all factories of ceramic insulators, polymeric insulators […]
As electrical industry grows with bigger demands and supplies, electrical high voltage insulators has entered a new stage of production furious. More and more factories in India, big or small, has smelled the chance and are eager to grasp the profit. When we talk about power construction, we feel difficult to ignore an important electrical […]
