Outdoor Direct Burial Armoured Cable GYTA53 GYTS53 Direct Buried

GYTA53 uses metal strength member as central strength member to provide excellent strain performance of the cable. Double-jacket structure provide the cable nice properties of moisture resistance and crush resistance. Double armor structure provides cable good property of rodent-resistance. High strength loose tube is hydrolysis resistant. A layer of water-blocking material is applied around the cable core to prevent water ingress. It can be used for duct and direct buried application, suitable for harsh environments.

GYTA53-24B1.3

Product Description:

GYTA53 uses metal strength member as central strength member to provide excellent strain performance of the cable. Double-jacket structure provide the cable nice properties of moisture resistance and crush resistance. Double armor structure provides cable good property of rodent-resistance. High strength loose tube is hydrolysis resistant. A layer of water-blocking material is applied around the cable core to prevent water ingress. It can be used for duct and direct buried application, suitable for harsh environments.

 

Feature:

1. Good mechanical and temperature performance
2. High strength loose tube that is hydrolysis resistant
3. Special tube filling compound ensures a critical protection of fiber
4. Crush resistance and flexibility
5. The following measures are taken to ensure the cable watertight:
a. Steel wire used as the central strength member
b. Loose tube filling compound
c. 100% cable core filling
d. APL moisture barrier
e. Water-blocking material

 

Cable design:
  • 24 SM-fibers.
