High flame retardant drag chain power sheathed cables are used for equipment supply, and in the outdoor environment, transmission cable needs to be fixed wall, usually along industrial route. The bridge moves, extends more frequently, supply with a sling device, because there is no such special device on market, so use of existing card fixing method leads often squeezed damaged insulation layer...

High-voltage electricity lines are known to generate extremely low-frequency electromagnetic fields (ELF-EMFs). With the process of urbanization, increasing concerns has been focused on the potentially hazardous impacts of ELF-EMF on human health, and the conclusions are controversial. Little is known about the method of prevention against ELF-EMF induced healthy problems. A total of 186 male w...

Several regions of the U.S. have sought to restructure the electric power industry by separating the potentially competitive generation sector from the natural monopoly functions of electricity transmission and distribution. Under this restructuring scheme, a central authority, which we will refer to as the independent system operator (ISO), is given control over both the transmission system an...

We describe here a 1.52 m (5 ft.) diameter Impulse Radiating Antenna (IRA) for use in a high-voltage radar system that uses a single antenna and a directional coupler. This antenna, designated the IRA-6, was designed to operate at 30 kV. To accommodate the higher voltage, we introduced a number of new features, including a larger-diameter 100-ohm cable, cable stubs at the feed point, and gaps i...

Blumlein pulsers are well suited devices for high voltage pulse generation in the range of nanoseconds or microseconds. They consist of pieces of transmission lines charged in parallel and discharged synchronously in series into the load by using a single switch. The main problems with this type of circuit are the presence of the shield cable impedance that contributes to the power loss of the ...

A t almost any data rate, system designers would like to make cable assemblies transparent and have the freedom to disregard all the "fun" effects such as ISI, crosstalk, reflections, EMI, and the overall signal loss introduced by long assemblies. Designers have long been battling these effects and have wished many times that "if we could only get out what we put in, then we could spread the bu...
