Wooden Poles

Utility poles are commonly utilized to hold two sorts of electric power lines : distribution lines and subtransmission lines. Distribution wires carry electric power from local power sub-stations to customers. Often they carry voltages from 4.6 to thirty three kilovolts ( kV ) for at least thirty miles, and include step-down transformers to step the voltage down from the 1st voltage of the lines to the lower secondary voltage made use of by the destination consumer. A service drop carries this lower voltage to the customer's grounds. Subtransmission lines carry higher voltage power from regional substations to a local substation. They usually carry 46 kV, 69 kV, or 115 kV for distances up to 60 miles. Voltages of 230kV can be put on two- or three-pole towers. Transmission lines carrying voltages of above 230kV are typically not supported by poles, but by metal pylons ( known as transmission towers in the U. S. ).

For business or other sound reasons, for example to economize on space in built up areas, a distribution line is ordinarily carried on the same poles as a subtransmission line but mounted under the higher voltage lines ; a practice called "underbuild". Telecommunication wires could be supported by the same wooden poles that support the power lines ; poles so arranged are known as joint poles. They'd also have their own dedicated poles.

Transformers Jim, but not as we know it.

Power transformers and distribution transformers are the invisible part of energy provision that is essential in the delivery of power to the various power hungry entities that constantly demand it to make our 21st century lives possible. They step up and step down the power level respectively so that we don't experience power station level of power, nor a trickle that wouldn't power anything useful. This important aspect of the energy industry allows pole line hardware to operate and make further useful the power or societies live on.

Distribution Transformers

Distribution and power transformers come in a number of varieties. Oil filled transformers, dry type transformers, cast resin transformers, midel transformers. Capacity for distribution transformers is between 25kva to 10mva in all types of distribution & power transformers.

Distribution and power transformers are rated up to 36Kv. Oil filled, distribution transformers are generally manufactured completely in house and are hermetically sealed transformers, above 2000kva distribution transformers are fitted with a conservator and oil level indicator. Distribution transformers come with a large range of fittings, including, thermometer pocket, lifting lugs, earthing terminal, oil drain valve, rollers or skids, silica gel breather, buchholz relay, pressure relief device, elastimold plug in bushings, auxiliary box & protective relays.
