Description

Novel cable

Technical Field

The invention relates to the field of cables, in particular to a novel cable.

Background

A cable is a conductor made of one or more conductors insulated from each other and an outer insulating sheath that carries power or information from one location to another. Typically a rope-like cable made up of several or groups of at least two twisted conductors, each group insulated from each other and often twisted around a center, the entire outer surface being covered with a highly insulating covering. The cable has the characteristics of internal electrification and external insulation.

The copper core is hinged and the butt joint part of the copper core is wrapped through the insulating adhesive tape in the existing cable connection mode, however, the connection strength of the connection mode is limited, the copper core is easily dislocated and separated from the adhesive tape for a long time, the insulating adhesive tape is easy to melt and contract due to the fact that the butt joint part is not wrapped by an external protective layer, meanwhile, the situation that the wrapping is not tight easily occurs when an operator uses the insulating adhesive tape to wrap the insulating adhesive tape, and water vapor enters gaps of the adhesive tape, so that the situation that the later stage falls off is caused.
