Semiconducting Shielding for A-C Power Cable
Transactions of the American Institute of Electrical Engineers, 1946ELECTRIC SHIELDING of a-c power cable is provided primarily for the purpose of directing and confining the electric field within the insulation so as to prevent the occurrence of unduly high electric stresses in dielectrically weak directions or regions of a cable.

EMP coupling to coaxial shielded cables
IEEE 1988 International Symposium on Electromagnetic Compatibility, 2003A method for determining the effects induced within shielded cables by a high-altitude nuclear electromagnetic pulse (EMP), represented as a plane wave, is presented. The cable is regarded as a multiconductor line in which the EMP sources are impressed on the shield.

As discussed in the previous chapter, electronic cables and connectors contribute to system EMI and EMC problems as (1) emitters that radiated part of the conducted signal and (2) receptors that are susceptible to ambient electromagnetic fields. Therefore, the shielding objective is to confine EMI signals within (to solve emission problems) and outside

Shielded cable modeling in PSpice for shielding effect analysis
2012 Asia-Pacific Symposium on Electromagnetic Compatibility, 2012This paper gives a method to simulate the shielded cable in PSpice. The multiconductor transmission line theory is applied to deal with the cable system. The influence of the grounding conditions on the shielding effect is studied. Through simulations, it is observed that imperfect grounding of the shield can lead different cross-talk in the inner ...

In this chapter, we will discuss the fundamental concepts of the cable shield specification and design. Along with the cable EMC performance, we will address important problems pertaining to shield reliability and performance stability. We will also review some of the “nontraditional” and/or innovative processes, designs, and applications of cable ...

Shielding Effectiveness on Layers for Cables
2021Ultra-thin layers have a layer thickness of several monolayers to several nm (d ≈ 0.1 to 10 nm) [45]. Ultra-thin magnetic layers also have a possible absorption property if the electrical conductivity is kept low.

Shielded wires and cables are used within electrical and electronic system to reduce electromagnetic interference (EMI) within a system. The interference of concern is capacitive and inductive coupling from wire to wire. The termination of the shields for both capacitive and inductive coupling is critical and fully discussed.

Transfer Parameters of Cable Shields [PDF]
, 1995 In the preceding chapter, we developed a system model of cable shielding and introduced a fundamental relationship between the shielding model generality and relevancy. Central to this model (both conceptually and graphically—see Eqs. (2.116) and (2.117)—is the shield transfer function, which is intimately related to the shield design, largely without ...

Computation of currents and losses in the shields of cables
2005 IEEE Russia Power Tech, 2005Recently, the investigation of extremely-low-frequency magnetic field has drawn a lot of researchers attention. The magnetic field of overhead power transmission lines has been studied extensively. In the present paper with the aid of Ansys 7.0 software current and loss in the shield of cable are computed for single phase and three phase cables.

Cable Shielding Measurements at Microwave Frequencies
IEEE Transactions on Electromagnetic Compatibility, 2004A matched triaxial device is developed and constructed to measure the transfer impedance of braided coaxial cables at microwave frequencies. Full-design principles of the device have been developed and given in detail in the paper. The device is particularly suited for shielding measurements at frequencies up to 3.5 GHz, for which no comparable ...
