SCOPE: |
| |
1.1 |
This specification covers requirements for
an underground shielded cable designed
to transmit and receive signals between irrigation
satellites, central computers, weather
stations, and sensors. The cable utilizes
stranded insulated conductors, aluminum
shield and drain wire to minimize electrical,
magnetic, and radio frequency interference.
The cable also features stainless steel
tape armor for protection against rodents
and for shielding of lightning and power
surges. The cable is listed by UL or ETL or
CSA. |
