                        KYN28-12 indoor drawer style metal-clad electrical switchgear 


    

1. General
KYN28-12 (Z) indoor drawer style metal-clad switchgear is a set of power distribution device of rated voltage 3 to 12KV three-phase AC 50Hz of single bus bar and single bus bar segmental system. It is applicable to power transmission of the power plant, power receiving and distribution of the electric system and the substation of the industrial enterprises to fulfill the aims of control, protection and inspection.  

 

 

2. Use condition
Environment temperature:  -15°C to +40°C
Relative humidity: daily average ≤95%     monthly average≤90%
Height above sea level: ≤1000m
Earthquake magnitude ≤8  
No fire, explosion danger, serious pollution, or chemical erosion occasion.

 

3.Main characteristics
The structure of the cabinet is bolt by aluminum zinc alloy board after the process of CNC machine tool and multi bending technology;
All the operation can be done after the cabinet door is closed;
High protection degree, protect the intruder of sundries and pests;
Simple and effective “five-prevention” lock function, protect error operation;
Can adopt VS1 and CD4 vacuum circuit breaker;
Easy replacement of the circuit breaker and free exchange of the drawers;
The cabinet can be installed by the wall, maintenance in the front, which reduces the floor space;
Large space of the cable room can connect many cables;
The relay room and the cable room can respectively add a heater to avoid freezing or erosion.
