About Us

Who are we?

Contune International Corp Limited is a comprehensive manufacturer and supplier of electrical and electronics in China.

What is our business range?

We offer solutions to clients on the electrical power industry, including a full set solution of establishing electrical testing laboratory, helping manufacturers to build production lines of high voltage insulators, fittings and etc. or we directly produce composite insulators and export to overseas market with technical support.

What is your key products?

Our key products are production machines and test machines of insulators for overhead transmission lines and power substations, which are widely used by manufacturers of the polymeric insulators, ceramic insulators, glass insulators , as well as electrical labs of power grids.

What can your products do?

Our test equipment helps the user to do the test to their insulators, surge arrestors, line fittings from the material stage to final complete product so that we can know and control the quality on every step. While production machines help insulator manufacturers to fabricate their insulators with high efficiency and reasonable cost.

As an electrical insulator itself is an important item in overhead power lines, strict technical tests are necessary both in the production process and inspection. Our testing machines are designed into different purposes and functions according to specific technical requirements defined in IEC, ANSI, and other industrial standards.

Are you a manufacturer or a dealer? Where is your factory?

We are a manufacturer. Our factory locates in the Shandong province of China mainland. The nearest seaport Qingdao enables us to ship commodities to all ports around the world. We also have collaborating factories in other places in China to assist us in providing turn-key projects to our clients.

Who are you collaborating with nationally and internationally?

Our products have entered the majority of insulator manufacturers in China and high voltage electrical laboratories which are established by local power grids of more than 30 different provinces, as well as the national electrical lab in Bejing which is regarded as the top authority in the electrical field.

Internationally, we have been in cooperation with foreign countries early since 2011. Our equipment were used in Southeast Asia like Indonesia, in East Asia like India, in Europe like Russia Federation, in American continent like USA, Mexico, even in Africa like Tanzania.
They choose us not only because of the wide range of our equipment that covers as per IEC but also on consideration of quality, stability, reputation in the past, maintenance cost in long term and good services of commercial and technical.

Our Vision

We aim to build a hundred-years enterprise, a famous brand locally and internationally, with good reputation of products, services and social image. We are take steady steps to improving our hardware and management system, which ensures us to grow annually.
