COMPLETE SWITCHGEAR DISTRIBUTION DEVICES KRP-10 VA-630...3150 U3,T3
Complete switchgears are designed for receiving and distributing electrical energy with a frequency of 50Hz, a voltage of 10(6)kV with a rated current of busbars of 630,1000,1250,1600,2000,2500 and 3150A and are operated in areas with a temperate climate + 4C°.
Climatic type U3 or T3 according to GOST 15150.
Normal operation of the switchgear is ensured under the following conditions:
1. Altitude above sea level - no more than 1000 m;
2. The environment is non-explosive, not containing conductive dust, aggressive gases and vapors in concentrations that reduce the parameters of the switchgear to unacceptable levels;
3. Atmosphere type - II according to GOST 15150.
The main technical parameters of the switchgear are given in table 1.
The classification of the cabinets is given in table 2.
In the case of a double-row cabinet, the switchgear is equipped with busbar bridges. Busbar bridges are installed only on the outer cabinets. The distance between the cabinet facades should be 2000, 2500 or 3000 mm.
Example of a switchgear entry with a HV network voltage of 10 kV at a rated tripping current of 31.5 kA, climatic version U3
KRP-10 VA-31.5 U3 TU U 3.2-14152239-008:2010
When ordering, it is necessary to fill out a questionnaire and indicate the customer's payment and shipping details.
