Portals

Besides that, our company manufactures a wide range of steel Portals of outdoor switchgears (ORU) with a voltage of 35 kV, 110 kV, 150 kV, 220 kV, 330 kV.

According to their technological purpose, portals are divided into:

- Bus portal - for stringing wires of assembly buses (Sh)                                                                   

- Cellular portal – for stringing wires of the upper layer of cellular lead (Ya)                                     

- Jumper portal - for stringing wires of the jumpers lead (P)                                                             

- Transformer portal – for fastening wires of the transformer lead (Т)

Portals 35-150 kV are developed in two types:

1.Light type (marking L) with narrow base posts mounted on one foundation.

2.Heavy type (marking Т) with wide base posts mounted on 4 foundations.

Material used for construction:

Steel 3 – for common regions of construction with the designed air temperature of down to -40º С inclusive,

09G2S – for northern regions of construction with the designed air temperature of down to -55º С.

Portals are manufactured in accordance with standard albums developed by North-Western branch of Energosetproekt Institute:
