First of all, "Zheng Da" is a word, so you should write it in conjunction with the initial capital, just as your name is "Daqiang Gao" and "Daqiang" is a word, so you should write Daqiang.
Secondly, although equipment is an uncountable noun, it should be plural when representing various equipment, just as steel is an uncountable noun, but steel is used for various steels.
The following translation is for your reference (a real company name):
Suzhou Huaya Telecom Equipment Co., Ltd.
Suzhou Huaya Telecom Equipment Co., Ltd.
Finally, good luck!
