About Contune International Corp

Contune International Corp Limited is a comprehensive manufacturer and supplier in electrical field.

Our key products are testers for electrical insulators,production machines for insulators which are widely used by manufacturers of polymeric insulator, ceramic insulator, glass insulator in China, Russia, Brazil, Europe and south-east Aisa.

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

Our Products

We are manufacturing and supplying below products

  1. Insulator Tester

    Testing machines applied for perform mechanical test and electrical test on electrical high voltage insulator and its basic material.

  2. Insulator Production Machine

    Production machines are used for manufacturing electrical insulator production line. Like crimping machine, vulcanizing machine, injection machine and marking machine for polymeric insulator.

  3. Composite Insulator

    Composite insulator is also known as polymeric insulator. It is used for insulation of electricity, isolating conductors from metal poles and other items.

Our Vision

We commit to machinery of electrical field, aiming to build the best brand of testing machine and production machine. In the past years our products have gain high praise from power grids in more than 13 province in China, national laboratories from Bejing and dozens of major manufacturers of insulators, bushings, conductors, metallic fittings and other line accessories. Our machines are also exported to overseas market, where there are lots of factories like Brazil, Russia, Southeast Asia and etc. With stable performance and optimized design, these machines are widely accepted and still in good condition.
