2. Good air-tight and water repellence characteristics, so the branch cable can supply electrical power normally in the moist environment, and can install in the air and in earth. 良好的气密性和防水性,能在潮湿的环境中正常供电,也能露天及埋地敷设。
In general, creating the gradient microstructure in a wire requires a multistage process based on plastic deformation by twisting, compression bonding or friction–extrusion combination [254, 255]. The same concept was found effective to overcome the strength–electrical conductivity trade-off; dual ...
The termination of the down conductor to an earth electrode should be done minimum of 1 meter away from the structure and minimum of 0.5m depth inside the ground. Earth electrodes for each down conductor shall be provided. Connection of down conductors to gutters or down-spouts even if they ...
Hierarchically bonded architectures are not limited to the caged compounds; several compounds with other crystalline symmetries are reported to have quite distinct strong–weak bonding hierarchy. Qiu et al. investigated the lattice dynamics and thermal transport behaviour of Cu–Sb–Se compounds, Cu3S...
(2) Grounding of Electrical Equipment Non–current-carrying conductive materials enclosing electrical conductors or equipment, or forming part of such equipment, shall be connected to earth so as to limit the voltage to ground on these materials. (3) Bonding of Electrical Equipment Non–current-carr...

Shield could be grounded at both ends by Delikon EMI RFI Shield Termination Heavy Series Connector. Delikon heavy series connector provides a 360 degrees bonding of the shields, providing a low impedance path to ground. The armor over braided flexible conduit prevents EMI coupling to other cables ...
That standard requires that metal cable sheaths, metal pipes, and the like entering a building or similar installation be bonded as directly as possible to the earth termination of the lightning protection system, at the point of entry to the building. This bonding is necessary to avoid ...
Due to their electronic properties, as extensively discussed in a chapter in Part I of this book, CNTs have been considered for applications as electrical conductors (to replace metals), quantum nanowires or quantum wires (ideal one-dimensional conductor
Graphene has always been grown in a polycrystalline form, that is, it is composed of many crystals that are joined together with irregular chemical bonding at the boundaries between crystals ("grain boundaries"), something like a patch-work quilt. Large single-crystal graphene is of great interes...
