The invention further discloses a connecting method.

Description

technical field

[0001] The invention relates to the technical field of electric special optical cables, in particular to a splicing device for high-voltage power grid phase-line composite optical cables (OPPC, Optical Phase Conductor) and a splicing method for high-voltage power grid phase-line composite optical cables. Background technique

[0002] Optical Phase Conductor OPPC (Optical Phase Conductor) is a new type of special optical cable for power. It is an optical cable that combines optical fiber units in the phase line. It has the dual functions of phase line and communication. It is mainly used for voltage levels below 110kV, urban and suburban distribution power grid, rural power grid.

[0003] In the medium and low voltage power grids, especially the distribution lines below 35kV, some ground wires may not be erected, so it is impossible to install OPGW (Optical Fiber Composite Overhead Grand Wire, overhead ground wire composite optical cable). In all power grids,...
