Professional design and development, production and manufacture of various high quality industrial plugs, sockets, connectors and other products

Connecting the world with the core

Quality is our only faith. We have a professional team sparing no efforts for pursuit of perfect production. We equip with a series of inspection devices for the testing and ensuring of every product coming out. Both the quality and performance of Our products can match the international standard EN/IEC60309-2 and the national standard GB/T11919-2001. And can also pass the CE and ROSH compliant of the European authoritative testing organization. 


When we design the product, the first thing we need to do is make sure that our product can work in rated current for a long time. To keep the high quality, we use the experimental apparatus which can test the temperature-risk, product life, and mechanical property together for finish the test more fast and widely.


When we design the product, in addition to the consideration of performance indicators such as metal conductive parts, also emphasize the tracking index of plastic raw material, each material must be strict control of the development of CTI/PTI tracking test, so that products are better, better insulation, safe to use.  


The operational environment is the first problem we considered when we design the product. We need to make sure that our product can be used over the world. So we need to evaluate the flexible condition of environment for store, deliver, and use in dry-sands or abound with lots of dusts.
The sand dust test adopted the manual simulation of  sand & dust conditions. So we can ensure that whether they had long-term usage in al kinds of harsh natural environments


As we know, whatever the product , product can inordinately influence with all kinds of liquids, whatever they in operative or storage. It has varying effects on their raw materials and features and even can damage the structures when they are permeated.
Rainfall test can exam the product outside case’s stabilities and reliabilities of against the liquid.


We need to make sure the variable temperature at first when we design the product. Base on the variable temperature, we try to do the best feeling of inspection and extraction force.

The target of insection and extraction force test is translate the nastic feeling to the exactly data, base on the data, we can provide the information for design, improve, and inspect the product.


There are many type of nature environment and precipitating environment in the world, and hundreds of environment factor can effect the life of electrical equipment, especially for the temperature.

In the high temperature or low temperature condition, we can exam the product physical performance by the simulation. After the exam, we can judge the how is the performance of product by inspection.


Decrease the risk of risk fire disaster is necessary. The electrical equipment case more and more fire disaster in the modern life. The component of electrical equipment may be fire because overload or bad contact.
The glow wire test is use the simulation to know the risk of fire when the component is overload or glow in short time.
