Product Description

Product Description

ZTEM6 gas-insulated  metal-enclosed switchgear (ZTEM6 gas-insulated switchgear for short)is a  new generation of  small-sized  gas-insulated   medium-voltage   switchgear  designed,researched   and  developed  by  our  company   by learning from  advanced  technologies  abroad  and  combining  the  power  supply  system  requirements  in  China.

This series  of products  are  12KV/24KV/50HZ  three-phase  AC  indoor  high-voltage  power  distribution  equipment using low pressure SF6 gas as insulation and breaking medium.Based on the primary main wiring,use the bus con- nector  to  connect  the  ring  main  unit,load  break  switch  unit,integrated  electric  cabinet  and  circuit  breaker  unit  to-  gether  and  form   a  ring  network  power  supply  loop.The  ring  main  unit,load  break  switch  unit,integrated  electric cabinet and circuit breaker unit can be used independently as well.

 1,All-weather  operation:all-insulated,all-sealed  structure,not  affected   by  climate and  environment;2,strong  adaptability  to  the  environment:can  be  installed  in  wet, sandy,dusty,dirty,mining and other areas without special preventive measures;3,use safety:with a sound mechanical and electrical interlocking system;4,Compact struc- ture:the  minimum  unit  width  is  325mm;5,Modularization  and  combination  expan- sion are flexible and convenient,and the modules are connected by copper busbar;6, Optimization of product design  using  3D  models  and simulations:3D  model  design using 3D computer-aided design software;7,Maintenance-free:fully sealed structure and high level of protection to ensure that the product is not affected by the environ- ment,no need to clean,maintenance and other features.
