Problems solved by technology

However, the existing photoelectric composite cables mainly have the following problems: (1) The cable core is not round. In order to make the product round, a lot of fillers or thick sheaths are needed, which increases the cost; (2) the use of Ointment filling is not environmentally friendly, solidifies when the temperature is low, evaporates when the temperature is high, and the ointment overflows when used indoors or in the cables inserted into the box, causing environmental pollution; (3) The filling rope can only be used for gap filling. Does not effectively block water
