Switchgears for distribution transformer stations

(RVT, RD, RBTR Types – frame or grate switchgears for indoor brick and kiosk transformer stations)

RD, RVT, RBTR switchgears are LV switchgears designed for internal spaces of transformer stations 10, 22, 35 / 0.4 kV of the power up to 1×630 kVA or 2×630 kVA. These switchgears are designed and manufactured in compliance with ČSN EN 61 439-1 ed.2, ČSN EN 61 439-2 ed.2 and ČSN EN 61 439-5 ed.2 standards.

Technical specifications:

  • Nominal voltage: 3×400 / 230 V / TN-C, 50Hz
  • Nominal current of main busbars: max. 1000 A
  • Switchgear short-circuit resistance: 35 kA / 1 s
  • Protection against dangerous contact voltage: by automatic disconnection from the power supply
  • Switchboard cover: IP 20/00
  • Structure: welder steel frame from U-profile 35x35x3 mm or bolted from perforated profiles
  • Sheathing: 1.5 mm (or 2 mm) steel sheet
  • Surface finish: powder coating (RAL 7032, 7035, or as requested by the customer)

Basic dimensions [mm]:

a) RD, RVT switchgear:

width: according to the number of outlets, 600 to 1000 mm
height: 2000 mm
depth: 400, 500 mm

b) RBTR frame switchgear:

width: 1000 to 2000 mm
height: 1200 mm
depth: 300 to 450 mm

c) RBTR grate switchgear:

width: 1000 – 1200 mm
height: 1350, 1800 mm
depth: 300 mm
