Overview

Product Short Overview

The 1-5/8" corrugated feeder cable from Zhenjiang Worldpeak Communication Co., Ltd. is a heavy-duty 50 ohm feeder cable engineered for demanding radio frequency transmission systems. Featuring a 41.28 mm corrugated copper outer conductor, a 36.5 mm closed-cell foam PE dielectric, and a 17.3 mm copper-clad aluminum center conductor, this 1-5/8" corrugated feeder cable achieves ultra-low attenuation across long transmission runs. Enclosed within a durable 46.5 mm Black PE jacket, this high-power RF feeder cable delivers 89% velocity of propagation and robust mechanical protection for cellular base stations, broadcast towers, and outdoor wireless networks requiring uncompromised signal integrity.

Detailed Product Description

In high-power telecommunications and broad-scale broadcasting networks, minimizing transmission line loss is vital for system performance. The 1-5/8" corrugated feeder cable manufactured by Zhenjiang Worldpeak Communication Co., Ltd. serves as a primary RF feeder cable designed specifically for permanent outdoor tower runs, high-power broadcast systems, and base station main feeds.

Unlike standard braided or foil coaxial cables that experience high attenuation and signal degradation over long distances, this 50 ohm feeder cable utilizes a solid annular corrugated copper outer tube. This solid outer shell creates a seamless electromagnetic barrier with shielding effectiveness exceeding 90 dB. The structural design eliminates signal leakage, blocks external electromagnetic interference, and maintains precise 50 ohm impedance throughout demanding environmental conditions.

Internally, the 1-5/8" corrugated feeder cable incorporates a high-expansion 36.5 mm foam PE dielectric surrounding a 17.3 mm copper-clad aluminum inner conductor. This material selection optimizes electrical conductivity while significantly lowering overall cable weight compared to solid copper core alternatives. The closed-cell foam structure prevents water migration along the inner core, protecting electrical stability against moisture ingress. Wrapped in a UV-resistant 46.5 mm black polyethylene jacket, this corrugated copper feeder cable withstands continuous thermal cycles, severe weather, and physical stress in harsh outdoor environments.

Key Technical Features

  • Solid Corrugated Copper Outer Shielding: The 41.28 mm annular corrugated copper outer conductor delivers continuous 100% electromagnetic shielding (>90 dB) and high structural stability.

  • Ultra-Low Attenuation Characteristics: Designed for long-distance runs, achieving exceptionally low signal loss (3.3 dB/100m at 900 MHz and 5.8 dB/100m at 2.4 GHz).

  • High-Velocity Dielectric Architecture: The 36.5 mm closed-cell foam PE dielectric supports an outstanding 89% velocity of propagation while blocking longitudinal water movement.

  • High Power Handling Capacity: Supports up to 40 kW peak power ratings and voltage withstand levels of 8000V DC for high-output transmitter connections.

  • Heavy-Duty Weatherproof Protection: The 46.5 mm black PE jacket provides long-term UV stabilization and thermal operating stability ranging from -40°C to +85°C.

  • Optimized Center Conductor: The 17.3 mm copper-clad aluminum center conductor leverages the skin effect to deliver copper-grade RF performance with reduced mass.


Engineering Advantages & Technical Expertise

Attenuation Efficiency in Long Tower Runs

As feeder length increases on cell towers or broadcast masts, RF attenuation directly reduces transmitter efficiency and coverage area. Smaller cables like 1/2" or 7/8" feeders suffer significantly higher insertion loss over extended distances.

The 1-5/8" corrugated feeder cable engineered by Zhenjiang Worldpeak Communication Co., Ltd. solves this power loss issue through its substantial physical diameter and solid outer conductor. By minimizing internal conductor resistance (DC loop resistance at 0.8 ohm/km), this 1-5/8" corrugated feeder cable ensures maximum power transfer from transmitter shelter equipment to top-mounted antennas.

Skin Effect Optimization and Material Engineering

High-frequency alternating current moves predominantly along the outer surface layer of a conductor—a principle known as the skin effect. By utilizing a precision 17.3 mm copper-clad aluminum inner core, this RF feeder cable places high-conductivity copper exactly where the RF energy travels, while maintaining a lightweight aluminum interior core. This construction maintains top-tier signal transmission efficiency while keeping cable weight at 1.85 kg/m, reducing structural load on tower climbing legs and cable hangers.

Frequently Asked Questions (FAQ)

Q: How does this 1-5/8" corrugated feeder cable compare to flexible braid coaxial cables?

A: Unlike braided cables that use wire meshes and foils, this 1-5/8" corrugated feeder cable utilizes a solid copper outer tube. This design provides significantly lower signal attenuation, higher power handling capacity (40 kW peak), superior shielding (>90 dB), and extended operational lifespan in harsh weather environments.

Q: What are the key installation requirements for this size feeder cable?

A: Installation requires maintaining a minimum bend radius of 250 mm to avoid kinking the solid outer copper tube. Because of the cable weight (1.85 kg/m), vertical tower runs require certified cable support grips to prevent physical strain on the upper connector interfaces.

Q: Can Zhenjiang Worldpeak Communication Co., Ltd. supply factory-terminated cable assemblies?

A: Yes. Zhenjiang Worldpeak Communication Co., Ltd. manufactures complete factory-terminated assemblies with 7/16 DIN, 4.3-10, or EIA Flange connectors, each fully tested for low VSWR and long-term environmental sealing.
