With increasing requirements for power supply reliability and high-quality service, live-line maintenance has been widely adopted. In this process, insulated hand tools for live working have become indispensable. These tools come in many varieties and are used frequently. As live-line working technology becomes more widespread, their demand and range of applications continue to expand, while tool quality directly affects operational safety and reliability.

The GB/T 18269 standard (modified adoption of the IEC international standard IEC 60060-1) plays an important role in ensuring the quality of insulated tools and standardizing industry development. As one of the key testing procedures in the hand tool industry, dielectric withstand testing is particularly important for ensuring tool insulation performance and safe use. With the growing adoption of live-line working, reliable hipot testing equipment not only helps manufacturers improve product quality but also provides strong technical protection for operator safety. With a high-voltage output of up to 20 kV, the EEC 7470 Series Hipot Tester provides an ideal testing solution for the hand tool industry.

According to GB/T 18269, insulated tools are required to withstand a 10 kV power-frequency voltage for 3 minutes. This applies to insulated tools used for live working, such as screwdrivers, pliers, and wrenches, as well as other high-voltage tools for special applications. This requirement ensures long-term stability and high-voltage insulation performance in energized environments, placing higher demands on the performance of testing equipment.

As a high-performance hipot tester, the EEC 7470 Series is specifically designed to meet the high-voltage testing requirements of the hand tool industry. It offers the following features:

In the face of increasingly stringent industry standards and market demands, choosing a high-performance hipot tester is crucial for hand tool manufacturers. The EEC 7470 Series Hipot Tester not only complies with the requirements of GB/T 18269 / IEC 60900, but also provides strong support for manufacturers to improve product quality and market competitiveness through its high accuracy and high testing efficiency.
