It is widely used in power utility communication systems and high-voltage areas where metal-free and high protection cable is required.

Structure & Design

GYFTY53 is designed with a robust fully dielectric structure for maximum protection and stability.

• Central strength member: FRP (Fiber Reinforced Plastic)
• Loose tube: High-modulus plastic tube filled with water-blocking gel
• Water blocking system: Gel or water-blocking yarn throughout the cable
• Inner sheath: Protective polyethylene layer
• Armoring: Non-metallic reinforcement layer (for enhanced protection)
• Outer sheath: Double-layer PE jacket for superior mechanical and environmental protection
• Metal-free design: Fully dielectric construction, no steel or aluminum components

This double-sheath armored structure ensures strong resistance against crushing, moisture, and rodent damage.

Applications

GYFTY53 is suitable for demanding installation environments where high protection and electrical safety are required.

• Direct burial in underground telecom networks
• Duct installation in harsh environments
• Power utility communication systems
• High-voltage areas and substations
• Rural and long-distance backbone networks
• Areas with strong electromagnetic interference

Advantages

• Double-layer protection: Excellent resistance to mechanical damage
• Fully dielectric design: Safe for high-voltage and lightning-prone areas
• Anti-EMI performance: Stable signal transmission without interference
• High moisture resistance: Water-blocking system ensures long-term reliability
• Rodent protection: Strong outer sheath resists damage from rodents
• High tensile strength: Suitable for long-distance and complex installation
• Corrosion-free structure: No metal components, suitable for harsh environments

FAQs

Q1: What is the difference between GYFTY and GYFTY53?

GYFTY is a standard non-metallic cable, while GYFTY53 has an additional armored and double-sheath structure, offering much higher mechanical protection.

Q2: Can GYFTY53 be used for direct burial?

Yes, GYFTY53 is specially designed for direct burial applications due to its strong armored structure and double PE sheath.

Q3: Is GYFTY53 suitable for high-voltage environments?

Yes, its fully dielectric design makes it ideal for installation near power lines and electrical substations.

Q4: Does it contain any metal parts?

No. GYFTY53 is a completely non-metallic fiber optic cable, providing excellent lightning and EMI resistance.

Q5: What fiber types are available?

It supports G.652D, G.657A1/A2 single-mode fibers, and optional multimode fibers such as OM1–OM4.
