Not long ago, a well-known lighting manufacturer found our Shenzhen Greenway Electronics Co., LTD., asking whether our company can provide a 10kV lightning protection device that can pass the extreme test requirements of their foreign end customers? Before this lamp manufacturer, has found several lightning protection device suppliers, including some big name lightning protection device manufacturers have provided samples, but unfortunately failed to pass the limit test of their foreign end customers.

We are also curious, this lamp manufacturer‘s foreign end customers, the requirements of the lightning protection device can pass the limit test, in the end what are the requirements?

Before understanding the requirements of extreme testing required by foreign end customers, we first understand the normal testing standards in the major regions of the world. At present, the world‘s mainstream test standards in the lightning protection device safety test, L-N, N-E, L-E these three circuits have to do surge test, the test standard for each circuit surge is to do 15 surge impact, each surge interval time is 60 seconds; After each loop has passed 15 surge tests, it needs to be replaced with a new sample to do the surge test of the next loop, so when doing the surge safety certification test of the surge protection device, at least 3 samples need to be provided.

The limit test required by foreign end customers is:

(1) Each circuit should pass 40 surge tests, and the interval time of each surge is 60 seconds;

(2) It is not allowed to change the sample in the middle; That is to say, only one sample can do all 3 loops of the surge test, so this test sample needs to withstand a total of 120 surge shocks!

This is not an extreme test. It‘s a hell of a test! It is no wonder that the samples of some big name lightning protection manufacturers can not pass such a abnormal limit test!

As for why foreign end customers want to take such extreme testing requirements, we do not know, only know that this is the demand of customers. Our Shenzhen Greenway Electronics Co., Ltd. responded positively, revised and designed a new circuit solution, and finally passed the ultimate test of the hell level perfectly!
