Unipolar aluminum trolley wire, single pole copper trolley wire, multi-pole safety trolley wire, and double hooked copper trolley wire are also known as slip conductors. They are a group of power transmission devices for powering mobile devices.
Mainly divided into unipolar aluminum trolley wire, monopole copper trolley wire, steel trolley wire, multi-pole tube type trolley wire, no-slip wire, copper contact wire and other commonly used trolley wire. Unipolar trolley line, multi-pole type trolley line, non-joined trolley line belong to safety trolley line, steel body trolley line belongs to non-safe trolley line.
Due to the movement, mobile devices need to constantly change positions. In each different position, the mobile devices must be able to obtain power power at any time, otherwise they cannot move. At this time, the trolley line came into being. Several conductors are laid in parallel along the running track of the mobile device, and the power is turned on. On the moving equipment, a current collector that can take electricity from the conductor is installed. In this way, when the device moves, the current collector operates synchronously with the device, and the power is obtained from the conductor at any time and provided to the device so that the device can continue to move. The device consisting of these conductors and current collectors is called a trolley wire.
The power supply trolley wire device consists of three main components of the sheath, the conductor and the power receiver, and some auxiliary components. 1. Sheath: It is a semi-closed conductive tubular component and is the main part of the trolley wire. Its internal can be embedded according to the need for high 3-16 body rail as a power supply wire, each rail insulated from each other, thus ensuring the safety of power supply. And in the maintenance of electricity to effectively prevent maintenance personnel electric shock accident. The length of each pipe produced by the factory is 4m, which can be connected to any length required. Ordinary pipe can be made into a straight line, or it can be made into a circular arc shape according to special requirements.
2, conductor: The main material is copper, according to the cross-sectional area of ​​the commonly used 10 square, 16 square, 25 square 3, the receiver is a set of brush housing running in the catheter, by the placement of electricity institutions (travel, The forks (or traction chains, etc.) on trolleys, electric hoists, etc. are driven so that they can be operated synchronously with the power-using mechanism, and the power passed through the guide rails and brushes can be pumped to the motor or other control elements. The number of poles of the power acceptor brush has 3-16 poles corresponding to the number of guide rail poles.
Talking about the classification of safety wireline:
