• Quadaplex wire
3 hot legs with 1 neutral.
*Always 1 neutral wire on triplex or quad.
• Sch. 80 and 40
refers to thickness of conduit.
• A hand hole
is a small vault.
• Hand holes are made of polymer concrete or with high-density polychylene plastic.

Transformers
- x label designates a primary voltage of 7200v.
- The N label designates a 25kva unit.
- The h label designates a 15kva unit.
• Cross arms
Typical size: 9-8 pins. Others include: 2,4,6,8,10 pin
• Puget arms are made of Douglas fir.
• Wooden cross arms are predrilled with insulator pinholes and mounting holes.
• Primary
Conductor energized at over 750 volts.
• Secondary
Conductor energized below 750 volts
• Single phase
a voltage that is generated in a single winding of a generator. Abbreviated as 10.
• Three phase
A polyphase system of three equal voltages with fixed phase differences. Abbreviated as 30.
• Thumper
Underground fault locator.
• Transmissions
Lines and equipment from a primary source of supply to distribution center of wholesale point. Typically a higher voltage then distribution
• Distribtuion
- Lines and equipment between transmission facilities and point of delivery to the customer.
• Framing
The configuration of attaching guys, insulators and cross arms to poles.
• Deadend(deaded?)
In line construction where the conductor is terminated on one or both sides of a cross arm.
• H-frame
A type of pole construction using two or more poles and the poles are joined by cross arms and or braces
• Jumper
Electrical connection between two points
• Service
Conductor which runs from point of service (transformer or hand hole) to customers service entrance.
• Run
A length of underground (ug) wire between two points
• Takedown
Material removed from service.
• Whip
Preformed guy grip.
• P.E. Gas Pipe
A shelf life of two years before having to go into service

• SCH 40
is shipped in 10’ lengths (substation use only)
• SCH 80
Shipped in 10’ lengths (used where higher strength is needed).
• MSDS
Material Safety Data Sheet.
• Inspection Code A
The basic inspection provided by stores personnel to ensure the material arrived undamaged and conforms to description of purchase order (p.o.)
• Inspection Code B
This inspection is product specific and administered by performance group
