Description

A tensile mobile double-shielded control cable for ships

technical field

The utility model relates to a pull-resistant mobile double-shielding ship control cable.

Background technique

At present, as a kind of communication cable for transmitting signals, control cables have made outstanding contributions to the development of my country's communication industry.
