Underwater TV systems Composite Cable 300V
2x1.34mm2+3x0.22mm2+COAX75 OHM
Application
The cable contain coaxes, power conductors to allow cameras, lights and pan & tilt units to be powered,
controlled and video images carried to the surface. The cables all have Polyurethane outer jackets,
allowing them to be easily moulded to connectors to make underwater cable harness assemblies.
The composite cable for use in hostile marine environments
