Problems solved by technology

Closed-circuit television cameras are commonly used in monitoring on ships. When the communication cable is used for closed-circuit television cameras, additional twisted-pair wires and power cables are required, so that there are many supporting lines for closed-circuit television cameras, which is not convenient for on-site use and is easy to be messy.

Abstract

The invention discloses a cable for a ship marine closed circuit television camera and a manufacturing method thereof, belonging to the field of cables. A cable core comprises a coaxial cable, a twisted pair core wire and a power cable and is peripherally wrapped with a polyester tape lapped layer; the polyester tape lapped layer is peripherally wrapped with a tinned copper wire shielding layer which is peripherally wrapped with an outer sheath; a center conductor of the coaxial cable is outwardly wrapped with a coaxial cable insulating layer, a coaxial cable shielding layer and a coaxial cable sheath in order; the center of the twisted pair core wire comprises a group of twisted pair wire pair and a non-insulating copper conductor leakage wire; the twisted pair wire pair is formed by mutually twisting two single-stranded insulating core wires; each single-stranded insulating core wire comprises a twisted pair wire conductor in the center and a twisted pair wire insulating layer wrapping outside the twisted pair wire conductor, and the twisted pair wire pair and the leakage wire are externally wrapped with aluminum foil polyester composite tapes; the leakage wire is in electric contact with the aluminum layers of the aluminum foil polyester composite tapes; and the power cable comprises a power cable core wire conductor and a power cable insulting layer wrapping outside the power cable core wire conductor.

Description

technical field [0001] The invention relates to a multifunctional cable, in particular to a cable for a closed-circuit television camera of ships and marine engineering. The invention also relates to a method for manufacturing a cable for a marine closed-circuit television camera, which belongs to the technical field of cables. Background technique [0002] On May 27, 2009, the Chinese utility model patent application with the publication number CN 201247605 disclosed a combined communication cable, including a coaxial cable. The coaxial cable includes an inner conductor and an outer sheath. The digital communication cable, the digital communication cable and the coaxial cable are arranged in an "8" shape, and the digital communication cable includes an outer sheath, which is integrated with the outer sheath of the coaxial cable. Closed-circuit television cameras are commonly used for monitoring on ships. When the communication cable is used for closed-circuit television ca...
