• 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.
