Single-end service assembled chambers CSR 207V series
Single-end service assembled chambers CSR-207V are designed for power facilities with 3-phase AC power (50/60 Hz) of 6 and 10 kV with resonant earthed or isolated neutral and correspond to technical specifications BKZHI.674712.002 TU.
CSR are manufactured both to meet the needs of the country's economy and for export and are used as switchgear, including modular ones of 6 - 10 kV, used to receive and distribute power to industrial and agricultural facilities, power supply stations and substations for railway transport. Operating principle is based on the main and auxiliary circuits of the chambers.
CSR chambers can be used as a high-voltage device (HVD) for compact transformer substations of the KTP-10/0.4, BMKTP-10/0.4 series with a capacity from 100 to 2500 kVA.
Climatic version - N and T, location category - 3 as per GOST 15150-69.
