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 […]
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 […]
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 […]
The creation of composite insulator started before the 1960s. This new insulator was firstly applied in America and then in France and Germany soon afterwards. It was quite slow for user to accept insulator with silicone rubber material in the beginning as most technical innovation would have some key problems to solve in the history. […]
Contune International Corporation and her collaborating factory will attend IEEE PES T&D Conference and Exposition in Danver,Colorado,USA from 17th to 19th April. Our booth no.:907 By our manufacturer name: Zibo Qianheng Automation & Engineering Co.,ltd Here we have our staff to introduce our testing machines and production machines of composite insulator, ceramic insulator and glass […]
Composite insulators consist of an insulating core, bearing the mechanical load protected by a polymeric housing, the load being transmitted to the core by end fittings. Despite these common features, the materials used and the construction details employed by different manufacturers may be quite different. Some tests have been grouped together as “Design tests”, to be performed only […]
Contune International Corporation and its headquater company Qianheng Automation have participated in World congress of electrical field held by INMR in Barcelona Sitges. The congress started on 5th November to 8th November 2017. The 2017 INMR WORLD CONGRESS has brought hundreds of power engineers from across the globe to Sitges this year, many of which have given presentation […]
International standard IEC 61284:1997 “Overhead lines – Requirements and tests for fittings” has defined requirements and test methods of electrical fittings (line hardware) for overhead lines. The complete IEC standard includes English and French language version, it’s too long and a little difficult for quick explore. Here we quote the content of IEC 61284 for […]
