The Development of Standards

To promote the advancement of explosion-proof technology, support industry standardization processes, and enhance the quality of enterprise products, CZ has been actively involved as a member of the National Explosion-proof Electrical Equipment Standard Technical Committee since 2008. CZ has played a key role in the formulation and revision of over 20 national standards, including the GB12476 series for dust explosion-proof standards and the GB3836 series for explosive environment explosion-proof standards.

Responding to the Zhejiang Provincial Government's initiative to enhance the quality and performance of 'Made in Zhejiang' products, CZ took the lead in drafting the T/ZZB1508-2020 'Explosion-proof Signal Light Button Module' group standard in 2019.

Philosophy of The Technical Department

Never stop exploring unsolved technical problems, with safety as the core and practicality as the basis, and the constant pursuit of perfection lead to the solving of impossible problems.

Innovative Gene

Launching core-pulled explosion-proof fluorescent lamps has brought great convenience to users through innovative attempts.

Breaking traditional thinking, we introduced the building block type aluminum alloy explosion-proof distribution box, enhancing safety during installation and maintenance with spliced explosion-proof products.

Introducing full plastic explosion-proof products has achieved component-level explosion-proof safety, aligning with international standards.

As the first domestic company to achieve ATEX certification from DNV, we have begun our global expansion.

We proposed and applied the maximum dissipated power method, established a system database through precise temperature testing, greatly improved the efficiency of each explosion-proof unit, and provided quantitative and reliable data support for customers' special customized products.
