Product Details

Design Parameters:
Innerduct: Black high density polyethylene (HDPE) meeting ASTM 3350 requirements with TC-7 wall thickness.

Armor: 6 mil steel with adhesive polymer applied to one side. The minimum bond strength of the steel to the outer jacket is 4 lbs. per square inch.

Jacket:
• 660 mil thick HDPE meeting ASTM 3350, nominally orange or black but can be colored to your specifications. Ratings
• The duct is composed of black (other colors available), highdensity polyethylene meeting the requirements (Class C, Grade PE33) of ASTM 3350 — Standard Specification for Polyethylene Plastics Pipe and Fittings Material.

Applications:
• PEST-Duct® is a specially manufactured HPDE duct that is used where additional mechanical protection of cable is of primary importance. Suitable for both aerial and buried installation, this construction combines the protection of a metal armor with the low cable pulling friction and and low dielectric constant of HDPE. It is shipped with sealed ends to prevent entry of moisture and other contaminants.
• PEST-Duct can be supplied empty, with a pull line, or with Draka cables preinstalled. Conductors available include THHN/THWN, EPRUSE, XHHW-2, RHH/RHW-2, XLP-USE, L-824B or C airport lighting cable, fiber optic cable, paired communication/coax cables, aluminum conductors and medium voltage cables. Tests have shown that the average lightning resistivity of PEST-Duct is up to 140kV.

Specifications and Ratings:
• ASTM D3485 – Standard specification for smooth wall coilable polyethylene (PE) conduit (duct) for preassembled wire and cable
• HDPE meets the requirements (Class C, Grade PE33) of ASTM D3350 – Standard specification for polyethylene plastics pipe and fittings material
