Armored Direct Buried Cable (GYTA53) 
Details

888.png


Fiber Type: G652D; G655C; 657A1; 50/125; 62.5/125; OM3; OM4 As Options

 

Application: Applicable to long-distance communication and inter-office communication.

Erection Method: Overhead, pipe laying and direct burial.

 

Main Features:

1. Accurate control of fiber excess length and SZ stranded method to ensure that the cable has excellent mechanical and environmental performance.

2. The material of the loose tube is with excellent hydrolysis resistant performance and high tensile strength, and the tube is filled with special fiber grease in order to provide crucial protection for the fiber.

3. The structure of double-layer armoring and double-layer sheathing improves the cable’s performance of pressure resistance, bulletproof, moisture resistance, and effectively prevents the cable from rodent bite.

4. Following methods are adopted to ensure the cable’s excellent water-resistant performance:

a) Single steel wire central reinforcement.

b) The loose tube is filled with special waterproof compounds.

c) Cable core is filled with special grease.

d) Coated APL moisture-resistant layer.

e) Two-side coated PSP moisture-resistant layer.

f) Good water-blocking material to prevent the cable from vertical water penetration.

5. Maximum fiber number: 288.
