Product Details
Design Parameters:
Duct: Modified PE with low smoke and flame-retardant additives. Schedule 40 or Schedule 80 duct is available in sizes from 1 to 3 inches in diameter. Different colors and duct with a molded-in longitudinal stripe for identification are available.
Applications:
• LSZH duct is for use in facilities where flammability and smoke generation are a concern. It is a non-metallic duct made of modified polyethylene (PE) with low-smoke and flame-retardant additives.
• LSZH duct can be supplied as an empty tube, with a pull line or with Draka cables pre-installed. It is shipped with sealed ends to prevent entry of moisture and other contaminants.
Specifications and Ratings:
• GR-356-CORE for Fiber Optic Duct
• ASTM D-2447 Standard Specification for Polyethylene (PE) Plastic Pipe, Schedule 40 and 80, Based on Outside Diameter.
• ASTM D-6070 for physical properties
• NEMA TC-7 Compression & Recovery, 85% minimum
• NEMA TC-7 Crush Resistance, NEMA TC-7 Table 4-1
• NEMA TC-7 Impact Test (room temp), NEMA TC-7: No cracks > 30% max
• NEMA TC-7 Limiting Oxygen Index, ASTM D-2863: 28 minimum
• NEMA TC-7 Environmental Stress Cracking, ASTM D-1693, Test Condition C: No cracks > 20% max, 192 hr. exposure, 100% Igepal CO-630
• NEMA TC-7 Vertical Tray Flame Test UL-1581: No propagation
