Contact network sectionalisation point is a linear device of the traction railway power supply system designed for electrical connection of contact network sections in order to reduce losses of electrical energy, for selective disconnection of one or several sections of the railway contact network in case of damage on it (them) or for solving the above tasks simultaneously. Parallel connection point of the contact network is a linear device of the traction railway power supply system designed for electrical connection of the contact network sections of the main tracks of the double-track section of the railway line in order to reduce voltage and electrical energy losses in the contact network.
