This system consists of key components are as follows.- feed power from the power station, or transmission of electricity, the electric 2 phase (A-B B-C C-A), or มายังสถานี get electricity to converted into electricity driven type 1 phase. (L-N).- powered power station (Traction Substation: TPS) serves as a pressure converter station is located along route electricity. About once every 30-40 km.- feed electricity from power stations is driven to OCS.- between series switch circuit is cut Section Post (SP) to divide the voltage difference from the mid-1990s one phase circuit during the late OCS. From the TPS on both sides, including the station itself.- other assemblies, such as switches, circuit protection devices, editing circuit breaker and accessories other separate circuit for operationEquipment for overhead wire system (Overhead Contact System: OCS) consists of a line, Contact wire Messenger wire dropper jumper,,,, Neutral section insulator, poles, (Pole) or support structure tendon brings various (Support Structure), Tensioning set and a set of weighted (Counter weight) etc.
