Zhejiang Brwor Electric Co.. Ltd. was established in 2005, located in Yueqing city, Zhejiang province, China. There is 30 kilometers from Wenzhou airport.
Brwor is specialized in medium Voltage Electrical Equipment, as like C-GIS switchgear, solid insulated ring network cabinet, vacuum circuit breaker, load switches, and others core unit of ring main unit related.
Browr covers an area of 11.565 square meters, with a building area of 11.000 square meters, which is domestic key research and development and manufacturing of high-tech middle voltage switchgear enterprise. The new plant with 33335 square meters will put into use in the ending of 2022. And we have installations of more than 270,000 C-GIS switchgear all over the world(since now main market China).
We make per key part of RUM in our factory and have strict QC process. The process of QC as follows:
Incoming inspection – inspection – process inspection – quality inspection – delivery inspection. There is inspection records for each accessory and contract product,easy inquiry.
Contact with us by email or whatsApp, and inform us the requirements. T/T is optimized, we aks for advance payment and balance should be paid off before shipping usually. L/C is available.
Min. order is 1 set.
RMU is custom made product, we will according to your requirements to make it. The technical question will referred.
Annual output 20,000 units.
we have installations of more than 270,000 C-GIS switchgear all over the world(since now main market China) since 2022 May.
Sea shipping usually. But parts also recommend air shipping in case of urgency.
There are Wenzhou or Ningbo or Shanghai port near our city and will arrange loading after order finish then.
The warranty period is 24 months. “three guarantees policy”,Guaranteed repair, replacement and return due to quality proble.Exceeding the guarantees period, we provide maintenance accessories with discount .After received a request ,we will make a response within 12 hours.In case of overseas after-sales service, we will borne the domestic charge, the foreign part shall be borne by customer (including but not limited to visa, accommodation, travel expenses, staff salary etc.)
The main products are 10/33KV RMU.
Now we have an area of 11.565 square meters plant,and the new plant with 33335 square meters will put into use in the ending of 2022.The number of employees is around 180.
