		Overhead line parts now often use grp insulation instead of the old composition, or synthetic parafil insulated rope instead of the steel wire, so eliminating separate insulators altogether.
		Performance of the collector is heavily dependent on the mass of the collector head and the performance will affect the wear of overhead wire and fittings and hence maintenance costs of the system.
		To achieve this there is always a choice between using the steel span wire (which may be stainless instead of the old galvanised wire) with its separate in-line insulators to provide the insulation levels.

		Thus it has long been recognised that electricity and telephone overhead wires have a visual impact and detract from a landscape's natural beauty.
		Since then FLD has been campaigning more actively to reduce the impact of overhead electricity and telephone lines on the landscape and the recommendations of the report are being implemented by Penny Ozanne, a project officer working one and a half days a week.
		It helps to identify the most intrusive overhead wires in an area and has been used for this purpose both locally and at locations across the country.

	Shanghai to Clean up Overhead Wires
		The increasing number of overhead wire networks are causing concern to residents and officials alike who claim electrical wires and information lines are ugly and are blocking out pleasant views of the city.
		As planned, no new wires should be hung overhead and by 2005, 30 percent of wire networks shall be buried underground.
		To store the wires in the "common tunnel" is the solution that is technically applicable but investment still remains the largest obstacle, Gong said.

	J.H. Crawford: Short-Wire Tram Proposal
		The batteries would be recharged while the tram was under wires (8 seconds for braking, 15 seconds for the stop, and a further 8 seconds during acceleration, for a total of 31 seconds; the coasting phase lasts no more than 30 seconds).
		The only diversions from conventional practice are the installation of guides at the beginning and end of the overhead wire, to bring the pantograph into gentle contact with the overhead wire, and the provision of a modest battery bank.
		Finally, because the section with wires is so short (and could be integrated into a covered station), it would be possible to provide 3-phase power (requiring three conductors), which permits the use of small, light, efficient, and easily-controlled 3-phase motors.

		In Newton, city ordinances were designed to minimize the intrusiveness of overhead wires, requiring wires to be placed together in bundles and not strung helter skelter along the streets.
		No unused coil or loose end of wire may be left on the ground or remain attached to a pole for more than 24 hours.
		All unused or abandoned wires must be removed in 24 hours, or the owner or lessee of the wire must pay the expense of having the city do the removal.

		The decision to use AAA Catenary wires instead of Copper Cadmium wires for overhead traction is another evidence of the myopic planning by the Indian Railways.
		The Railway Board decided in 1990 to use AAA Catenary wires for overhead traction on lines that were being newly electrified.
		The AAA Catenary wires were estimated to have a useful life of 25 years, against which they were used for only 19 years.The replacement of AAA Catenary wires with Copper Cadmium wires is estimated to cost Rupees 4.51 crore.

		Overhead power lines are almost always less expensive to install than their underground siblings.
		They will put forth reasons concerning the aesthetic values of their community, the safety of having no wires swinging overhead etc., etc. Some of those arguments are understandable; crisscrossing wires overhead can be an eyesore among otherwise attractive architecture.
		Among reasons given by the PUC were that there could be a significant disparity between overhead and underground cable, and it would place an unfair burden on customers of the utility in other locations who, apart from being customers of the same utility, had nothing in common with the residents of the county in question.

	Overhead Wires - City of Buffalo
		Aside from maintenance issues, which aren't covered here, overhead wires become an item to deal with in the case of installation of swimming pools, enlarging a front or rear porch or dwelling where distance separations from existing wires would become less, raising a roof slope where separations become less, etc.
		A project for which close wires may become an issue should begin in part with a review with an electrical inspector of the project parameters, which will probably be followed by an inspection.
		In all cases where overhead wires would become too accessible, the two options are: moving the location where the wires land on the house, or re-routing them and bringing them to the house by buried conduit.

	High-wire act - The Boston Globe
		The task force is trying to form neighborhood survey teams to document places with double poles, low-hanging wires, and excess coils of cable outlawed by city ordinance.
		Underground wires have fewer outages from hurricanes and other destructive storms, although the damage that can occur takes longer to fix, according to a 2004 report by the Edison Electric Institute.
		The report also found that burying wires increases property values and reduces motor vehicle accidents (no poles to hit), electrical outages, maintenance costs, electrocutions, and the risk of brush fires.
