Description

Technical Field

[0001] The invention relates to the technical field of electric power, in particular to a breakpoint wiring device for an electric power cable. Background Art

[0002] Electricity refers to energy that uses electrical energy as a driving force. It is a secondary energy source that is converted from primary energy (such as coal, oil, natural gas, hydropower, wind energy, solar energy, etc.) through power generation facilities. For example, in a thermal power plant, coal combustion generates heat energy, which turns water into steam. The steam drives the turbine to rotate, which in turn drives the generator to generate electricity, ultimately converting chemical energy into electrical energy.

[0003] The power cable breakpoint wiring device is a device used to connect the cable breakpoints. When the cable is broken due to external damage, aging, short circuit, etc., this device can reconnect the breakpoints and restore the conductive function of the cable.
