652D 24F OPTIC FIBER CABLE

SPECIFICATION

1. Introduction ADSS Fiber Cable

The fibers are in jelly-filled loose tubes, laid up around a central nonmetallic strength member.
The cable is water blocked, aramid yarn reinforced and PE or AT sheathed. ADSS (All Dielectric
Self-Supporting) Cable is suspended from poles or towers in telecommunication and power
outside plant applications.

Features
• The lifespan is over 30 years
• Large span with the largest span of over 1000m
• Can be installed without shutting off the power
• Central strength member FRP gives high tensile strength
• Water blocking system ensures reliable waterproof performance
• PE or AT sheath ensures safety of cable in high voltage environment
• All-dielectric structure and light weight provide easy installation and good electromagnetic
resistance

Application
• Railways, power and telecommunication pole routes
• Can be used in areas with high electrical field strength
• Suitable for installation on poles and on the power distribution network
