Characteristics
High tensile strength of stranded wires meet the requirement of self-supporting and reduce the installation cost
Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fibre
The following measures are taken to ensure the cable watertight:
-Steel wire used as the central strength member
-Loose tube filling, compound
-100% cable core filling
-APL moisture barrier
Standards
GYTC8A cable complies with Standard YD/T 1155 as well as IEC 60794-1.

Note:
a. Suffix Xn denotes fibre type
b. The colour arrangements of fibre and tube are specified in the colour identification table
c. The cable shouldn‘t store in outdoor environment more than 6 months in order to keep the cable reel good state
