Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cables, in particular to a connectable photovoltaic cable. Background Art

[0002] Photovoltaic cable is a special cable used in solar energy systems. Its characteristics are determined by its special insulation material and sheath material, which can be specifically called cross-linked PE. After irradiation by an irradiation accelerator, the molecular structure of the cable material will change, thereby improving its performance in various aspects.

[0003] The continuation of photovoltaic cables refers to the situation where two photovoltaic cables need to be connected and extended during the installation, wiring or maintenance process. The stripping wiring method is the most common method for photovoltaic cable continuation. First, use professional tools to strip the insulation of the photovoltaic cables at both ends to expose the internal wires; then, connect the wires of corresponding colors to each other and fix them by crimping or welding; finally, use insulating tape or heat shrink tubing to insulate the joints to ensure a firm and safe connection; however, the above crimping or welding process is prone to loosening or disconnection, and the wire itself may be damaged, such as the insulation layer burning, metal conductor deformation, etc., affecting the service life and performance of the wire.
