UF wire

Description

Regency’s single conductor UF/TWU Irrigation Wire is manufactured for the purpose of direct burial power wire applications in accordance with Article 339 of the National Electric Code NFPA-70.

Conductor construction is soft drawn bare copper meeting the requirements of ASTM Specification B-3 and B-8. Gauge sizes 18 thru 8 are solid conductors. Sizes 6 thru 4/0 are stranded conductors.

The insulation is a high quality polyvinylchloride (PVC) for systems applications of up to 600 volts and conductor temperatures up to 60 C.

The UF/TWU Irrigation Wire is constructed in accordance with Underwriters Laboratories, Inc. standard 493 and 83, as well as CSA 22.2 No. 75.

Application

Suitable for use as power and control wire for irrigation systems.

Testing

Material must be able to pass the following tests without showing signs of degradation:

  • Cold bend: The insulation shall not show any cracks when sample is bent around a 3X mandrel after being subjected to –25 C for four (4) hours.

  • Electrical: AC test voltage, 60 seconds at 5000 volts.
  • Sunlight resistance test: Samples conditioned for 300 hours of carbon-arc or xenon-arc exposure.
