transformer neutral grounding protection device

详情

I. Product Use 
Provide over-voltage protection for neutral of **0 kV **0KV *3KV graded insulated transformers.

II. Product Features
 (1) Modular design, easy to choose type for different use.
(2) The mounting brackets adopt seamless steel pipes,better stability and beautiful appearance.
(3) Intelligent control units are equipped,electrical data can be uploaded via serial communications ports.
(4) Use limit design bases on severe weather every *0 years.
(5) High-voltage test equipment and test procedure ensure **0% delivery qualification rate.

 III. Specifications and Models

Notes:
1. To increase an intelligent control unit, the letter "z" can be added to the end of the original type; for example: If an intelligent control unit is to be added to THT-TNP***0/**0/I, the model should be: THT-TNP***0/**0/I-Z.
2. The supporting structure can be customized.
