Oil-immersed hermetically-sealed transformers (25-1250 kVA, 10(6)/0.4 kV)

Oil-immersed hermetically-sealed distribution transformers with power of 25-1250 kVA are intended for operation in power supply with voltage of 6 or 10 kV in open electrical installations in temperate and boreal climate conditions (operational temperature is from -60˚C to +40˚C according to State Standard Specification 15150-69). Such transformers are designed to step down a high voltage of supply network to the installed consumption level.

Oil-immersed hermetically-sealed energy-efficient transformers (63-1000 kVA, 10(6)/0.4 kV)

Oil-immersed hermetically-sealed energy-efficient distribution transformers with power of 63-1000 kVA are intended for operation in power supply with voltage of 6 or 10 kV in open electrical installations in temperate and boreal climate conditions (operational temperature is from -60˚C to +40˚C according to State Standard Specification 15150-69). Such transformers are designed to step down a high voltage of supply network to the installed consumption level.

Oil-immersed hermetically-sealed transformers pole-mounted (25-160 kVA, 10(6)/0.4 kV)

Oil-immersed hermetically-sealed transformers pole-mounted with power of 25-160 kVA are intended for operation in electricity networks with voltage 6 or 10kV in open electrical installations in temperate and boreal climate conditions (operational temperature is from -60˚C to +40˚C according to State Standard Specification 15150-69) with option of fastening on a concrete support.

Single-phase oil-immersed hermetically-sealed transformers pole-mounted (10-25 kVA, 10(6)/0.23 kV)

Single-phase oil-immersed hermetically-sealed transformers (pole-mounted) are intended for operation in electricity networks with voltage of 6 or 10 kV in open electrical installations in temperate and boreal climate conditions (operational temperature is from -60˚C to +40˚C according to State Standard Specification 15150-69) with option of fastening on a concrete support.

Oil-immersed hermetically-sealed flanged transformers (400-1000 kVA, 10(6)/0.4 kV)

Oil-immersed hermetically-sealed flanged distribution transformers with power of 400-1000 kVA are intended for operation in power supply with voltage of 6 or 10 kV in open electrical installations in temperate and boreal climate conditions (operational temperature is from -60˚C to +40˚C according to State Standard Specification 15150-69). Such transformers are designed to step down a high voltage of supply network to the installed consumption level.

Oil-immersed distribution transformers (25-630 kVA, 10(6)/0.4 kV)

Oil-immersed distribution transformers with power of 25-630 kVA are intended for operation in power supply with voltage of 6 or 10 kV in open electrical installations in temperate and boreal climate conditions (operational temperature is from -60˚C to +40˚C according to State Standard Specification 15150-69). Such transformers are designed to step down a high voltage of supply network to the installed consumption level.

Oil-immersed hermetically-sealed transformers for power supply of electrosubmersible pumps (100-630 kVA, 6(3)/0.38 kV)

Oil-immersed hermetically-sealed transformers with power of 100-630 kVA and voltage of 3 and 6 kV are designed for power supply of electrosubmersible pumps from alternate current network with voltage of 380 V and frequency of 35-70 Hz. Such transformers are operated in temperate and boreal climate conditions (operational temperature is from -60˚C to +40˚C according to State Standard Specification 15150-69).
