1. Ordinary connector It is used to connect two adjacent power cables.
In the high-voltage power cable line, the straight-through connector must maintain the flow of oil in the core of the self-contained oil-filled power cable, in addition to connecting the core conductor to ensure electrical communication.
2. Insulation joints Insulation joints have the same insulation structure and dimensions as ordinary joints. 110~220kV oil-filled power cable insulation joints are mainly used in large-length power cable lines, so that the metal sheath or metal shielding layer and semi-conductive layer of the power cables at both ends of the connection are electrically disconnected to facilitate cross-interconnection and reduce Cover (or shield) loss.
3. Plug-and-socket plugs Plug-and-socket connectors are the weakest link in the electrical performance of oil-filled power cable attachments, and they are also the most complex joints. It is mainly used for imperial impregnated paper-insulated power cable lines with a drop greater than the specified value to cut off the oil circuit to prevent the insulation of the high-end power cable from drying out, and the insulation oil pressure of the low-end power cable exceeds the specified value.
4. Steel pipe oil-filled power cable connector copper pipe oil-filled power cable connector has two kinds of common connector and half-stop connector.
Ordinary connector for the length of the power cable connection, its internal insulation structure is generally phased with the self-contained oil-filled power cable connector, the shell is a copper pipe with a diameter slightly larger than the power cable pipe. Half-stop stoppers for longer oil-filled power cable lines. It is a joint designed to avoid the loss of a large number of power cable sleeves in the event of an oil leakage accident. It is used to separate the oil supply section and allow the oil in the two sections to circulate through the power cable insulation or the bypass pipe.
There are several types of high voltage power cable connectors
The head of the high voltage power cable is used for the connection of the power cable itself, with connection joints, insulated intermediate joints, plug-in connectors for oil-filled power cables and steel pipe power cables, and the like.
