How to choose the appropriate oil detection equipment, transformer testing equipment, power testing equipment, high voltage testing equipment? How to ensure the quality of equipment products? How do I ship from China?

In this complete guide, you’ll learn everything you need to know about buying testing equipment from China.

Why import testing equipment from China?


When choosing a testing equipment supplier overseas, the first question is: which country should I source my products from? I won’t bother you with reasons like “China makes products at low cost”.

Which country is the world’s largest exporter of testing equipment?

I will answer directly, China is the largest exporter of testing equipment in the world.

Which countries import the most testing equipment from China? Equipment market highlights:

The testing equipment market is expected to grow at a CAGR of 11.9% by 2030. The testing equipment market is overtaken by rising awareness of maintenance cost savings and operational performance, and the global demand for testing equipment is expected to expand significantly over the next few years.

Testing Equipment Market: The regional testing equipment market is segmented into five major regions based on regional analysis: North America, Latin America, Europe, Asia Pacific, and the Middle East and North Africa.

What types of testing equipment are sold?

By understanding the functions of the testing equipment, you can have a good understanding of which testing equipment is suitable for you. You can choose the most suitable device for you according to the functions of different devices.

Dielectric loss measurement is a very basic method in insulation test. It can effectively detect the whole damp deterioration and partial defects of electrical equipment insulation. It is widely used in electrical manufacturing, installation of electrical equipment, handover and preventive testing. Measurement of dielectric loss of transformer, transformer, reactor, capacitor, bushing and arrester is the most basic method to measure their insulation performance.PS-FA Capacitan&Tan-Delta tester breaks through the traditional bridge measurement mode by adopting frequency conversion power supply technology, using single chip computer and modern electronic technology to automatically convert 

frequency, analog-to-digital conversion and data operation; it achieves strong anti-interference ability, fast testing speed, high accuracy, automatic digitalization and easy operation; the power supply adopts high-power switching power supply, and outputs 45Hz and 55Hz pure sinusoidal wave. Automatic pressurization can provide up to 10 kilovolts of voltage; automatic filtering of 50 Hz interference, suitable for field testing of large electromagnetic interference in substations. It is widely used in dielectric loss measurement of transformer, transformer, bushing, capacitor, arrester and other equipment in power industry.
