Description
The loose tube are made of high modulus plastics(PBT), which are filled with water resistant gel. The Corrugated steel tape is applied provide for moisture and crush resistance .Two parallel steel wire are embedded in the two sides of Inner PE sheath .Then the second layer of corrugated steel tape armor is applied over inner sheath which provide for high crush and tensile resistant.Outer sheath is made of UV resistance PE jacket.
Feature
Full cross-section water-blocking structure to ensure good water blocking and moisture resistance
Loose tube is filled with special ointment for a key fiber protection
Double-sided vertically-clad corrugated steel-tape armor effectively improves the resistance to lateral pressure
More than 30 years of service life.
