| XGN68-12 box-type AC Metal Enclosed Ring network switch equipment |
| Application | |
| The product is used for three-phase AC 50Hz 12kV power supply
system in the ring or the terminal power supply system from the
acceptance, distribution of electric energy or overload, short
circuit protection purposes, especially for oil-based, non-frequent
maintenance and operation of sites, but also to in box-type
substation. |

| Structural characteristics | |
| XG /, J68-12 box-type AC Metal Enclosed Ring network switch
equipment (hereinafter referred to as Ring Main Unit), is my
factory and China Electric Power Research Institute in 2002 for the
equipment of modern ring joint design requires the development of
the latest ring network equipment, it absorbed the essence of
similar products at home and abroad, and has a unique and
innovative, not only do the vacuum ring counter with an equal
volume of SF6 Ring Main Unit (available with interchangeable), but
also the perfect solution to the small size cabinet replacement
Fuse difficult and dangerous practical problems, and in order to
fully cover the same time small switchgear products developed with
load switches and circuit breakers to match,Compared with similar
products with practical, high degree of protection, maintenance and
overhaul convenience, wide coverage and many other obvious
advantages, is the first choice for |
