RSL TYPE OF MV SWITCHGEAR – OPTION 1, 2, 3, 5, 6, 7 – standard
Switchgear RSL oftype (Option 1, 2, 3, 5, 6, 7) are intended for use in the power industry, industrial plants as a typical switchgear in typical transformer stations and indywidual solutions.They are designed to work with a SN 15 kV and 20 kV networks.
It is an air insulated switchgear of welded construction made of steel sheets covered with paint coatings. Because of the type of used switches, it is available in the following options:
OPTION 1 – box of 650 mm pitch, switches operating in the back (reverse) type of system OR424TU2 (OR424TU2/R), OR524T2A (OR424T2A/R) with direct drives.
OPTION 2 – boxes of 850 mm pitch, circuit breakers working at the front (straight) type OR424PU2 (OR424PU2/R), OR524P2A (OR424P2A/R) with direct drives.
OPTION 3 – boxes of 850 mm pitch, circuit breakers working at the front (straight) type NAL 24-6A-170 LEL (NAL 17,5-6A-170 LEL), NALF 24-6A-170 LL (NALF 17,5-6A-170 LL) with indirect drives.
OPTION 5 – boxes of 850 mm pitch, circuit breakers working at the front (straight) type KL 20/630-230-EUK (KL15/630-175-EUK), KLF 15/630-175-SU (KLF 20/630-230-SU) with indirect drives
OPTION 6 – 650 mm pitch field; operating switches are used in the rear (opposite) type system OM-24/T/UD/160, OMB-24/T/BD/160 with direct drives.
OPTION 7 – boxes of 850 mm pitch, circuit breakers working at the front (straight) typeOM-24/UD/160, OMB-24/BD/160 with indirect drives.
