Abstract
A low-voltage electrical power cable that includes of at least one uninsulated ground conductor and at least one insulated power conductor. The ground conductor and the power conductor are covered with an electrically conductive composition such that the power conductor contacts the electrical conductive composition for improving the flow of a fault current to the ground conductor and to trigger a circuit breaker when the low-voltage power cable is damaged by generating the fault current without the presence of a ground check wire.
Claims28
A low-voltage electrical power cable comprising of:
- at least one uninsulated ground conductor and at least one power conductor, said at least one power conductor being substantially the same size in cross-section as said at least one ground conductor,
- wherein said ground conductor and said power conductor are covered with an electrically conductive composition such that at least said power conductor contacts said electrical conductive composition for improving the flow of a fault current to said ground conductor and to trigger a circuit breaker when the low-voltage power cable is damaged by generating said fault current without the presence of a ground check wire.
A low-voltage electrical power cable comprising:
- at least one uninsulated ground conductor;
- at least two low-voltage power conductors, at least one of said power conductors being substantially the same size in cross-section as said at least one ground conductor;
- and
- an electrically conductive composition in contact with said ground conductor and said at least two power conductors providing a path for a fault current to said ground conductor and wherein said ground conductor is substantially completely surrounded by said electrically conductive composition in order to trigger a circuit breaker when the cable is damaged by generating said fault current without the presence of a ground check wire.
A low-voltage electrical power cable, comprising of:
- an electrically conductive composition;
- at least one uninsulated ground conductor substantially embedded in said electrically conductive composition;
- and
- at least two low-voltage power conductors in contact with said electrically conductive composition, said at least one of said power conductors being substantially the same size in cross-section as said at least one ground conductor, thereby defining an electrically conducting path between said uninsulated ground conductor and said at least two insulated power conductors facilitating the flow of a fault current to said uninsulated ground conductor.
A low-voltage electrical power cable, comprising:
- at least one ground conductor;
- at least one low-voltage power conductor;
- an electrically conductive composition in contact with said at least one ground conductor and said at least one power conductor providing a path for a fault current to said ground conductor in order to trigger a circuit breaker when the cable is damaged by generating said fault current without the presence of a ground check wire wherein said ground conductor and said power conductor are embedded in said electrically conductive composition;
- and
- a jacket substantially enclosing said ground conductor, said power conductor, and said electrically conductive composition, said jacket having at least one substantially flat surface.
