Abstract
A wireline cable, method, and system for broadband communications and data transfer. The wireline cable comprises insulated conductors, arranged such that circumferentially spaced conductors surround a central conductor. One or more of the conductors is insulated with a magnetic permeable insulation configured to reduce electrical interference with an adjacent conductor.

A wireline cable, comprising insulated conductors arranged such that circumferentially spaced conductors surround a central conductor, wherein one or more of the conductors is insulated with a magnetic permeable insulation configured to reduce crosstalk between transmission modes during high frequency data signal communication through the conductors, and wherein which conductors are insulated depends on the transmission modes used.
A method of transmitting data signals over a wireline cable, comprising:
- applying voltages to insulated conductors of the wireline cable to transmit the data signals with high frequency in transmission modes, wherein the insulated conductors comprise circumferentially spaced conductors surrounding a central conductor;
- reducing crosstalk between transmission modes involving adjacent conductors during communication by insulating one or more of the conductors with a magnetic permeable insulation, which conductors being insulated depending on the transmission modes used, and
- receiving the signals at a downhole tool coupled to the wireline cable.
A wireline system, comprising:
- a controller;
- a downhole tool locatable in a borehole;
- and
- a wireline cable coupled to the downhole tool and operable to provide power and an electrical communication path for data for the downhole tool, the wireline cable comprising insulated conductors arranged such that circumferentially spaced conductors surround a central conductor, wherein one or more of the conductors is insulated with a magnetic permeable insulation configured to reduce crosstalk between transmission modes during high frequency data signal communication through the conductors, and wherein which conductors are insulated depends on the transmission modes used.
