Abstract
Coaxial video push-cables are disclosed. One embodiment includes a central conductor and a multi-dielectric stack of multiple concentric tubular layers disposed around the central conductor having one or more structural layers and one or more impedance tuning layers where the thickness of materials of each layer are selected to provide a pre-defined elastic modulus and electromagnetic impedance, an electromagnetic shielding layer, and a jacket enclosing the shielding layer, multi-dielectric stack layers, and central conductor.
Claims16
A coaxial video push-cable, comprising:
- a central structural element of dielectric material selected to have a predefined elastic modulus;
- a conductor layer disposed about the central structural element;
- an impedance tuning layer disposed about the conductor layer, comprising a dielectric material having a thickness selected to provide a predefined electromagnetic impedance;
- a shielding layer disposed about the impedance tuning layer;
- and
- a jacket enclosing the shielding layer, impedance tuning layer, conductor layer, and central structural element.
A jetter video push-cable, comprising:
- a central hose having a channel to transmit and dispense pressurized water;
- a conductor layer disposed about the central hose;
- an impedance tuning layer disposed about the central hose having a thickness of a material selected to provide a predefined electromagnetic impedance;
- and
- a shielding layer disposed about impedance tuning layer.
A jetter video push-cable, comprising:
- a hose adapted to dispense pressurized water;
- a video push-cable disposed in the hose;
- and
- a hollow cavity between the hose and video push-cable for the conveyance of water.
