Power Line Pole Utility Pole Diagram

Discusses the basics of safety as they relate to overhead utility lines including a diagram of a typical joint pole layout.

Power line pole utility pole diagram. Additional stress placed on utility s poles oy licensee s attachments. In this article electrical engineer jim orosz p e. Back to utility pole diagram. The placement of different types of overhead lines on poles is governed by the national electric safety code.

Most utility poles are known in the jargon of the business as joint poles because they carry the hardware of two or more companies. Without a static wire lightning induced voltage would otherwise build up on power line conductors during a lightning strike and cause damage. Static wire the static wire is the pole s top wire which bleeds lightning surges off the power lines during a storm. The grounding conductor line connects to this rod and when lightning hits a static wire or the pole the electricity travels from the static wire to the grounding wire and then is fed down into the rod where it dissipates safely into the earth.

In order to maintain the reliability of services dependent on utility poles and to protect. What s on a utility pole. The 2011 windstorm in southern california edison s sce territory during which more than 440 000 customers lost power after utility poles and attachments were knocked down in a windstorm.

Vertical zones on joint poles are dedicated to various power distribution cable and telephone service uses usually in descending order. In electrical grids they are generally used to carry high voltage transmission lines that transport bulk electric power from generating stations to electrical substations. The grounding rod is located in the ground near the base of the utility pole. A transmission tower or power tower alternatively electricity pylon or variations is a tall structure usually a steel lattice tower used to support an overhead power line.

Licensee may not place guy wires on the anchors of utility or third party user without prior written consent of all attaching entities and anchor. Anchors and guy wires must be set on each utility pole where there is a turn or angle and on all dead end utility poles. Centerpoint energy s poles supporting electrical conductors of less than 69 kv not including poles used solely for electric power transmission dedicated metal poles street light poles and all other special purpose poles or pole lines of non standard design that do not support centerpoint energy s electric distribution system. Wildfires were reportedly caused by downed power lines.
