ETG poles of railway tractions



Pre-tensioned concrete supporting spun ETG constructions are designed for the construction of railway and tramway tractions installed on foundations with screws properly distributed at their ends.

At the bottom, an ETG pole has a steel head with four mounting holes appropriately spaced, depending on the type of foundation and the function of a pole. Above the head, the pole has a shape of a truncated cone with a ring cross-section. The external diameter of the pole decreases by 15 mm per one meter of length, starting at the base. The hole inside the pole has been used to drop traction bonding cables. At the bottom, the earth wire is connected to the head. The head has holes Ø13 for an external earth wire. An ETG pole is fitted with M8 screwed sleeves for fixing the track axis control signs.
