INTRODUCTION

Product Overview

Our 2×26AWG underwater neutral buoyancy twisted pair signal cable is professionally engineered for miniature signal transmission in underwater environments. Featuring high-purity copper conductors, PE insulation, and premium foam PUR outer jacket, this 300/500V low-voltage signal cable delivers stable, interference-free signal output with excellent neutral buoyancy performance, perfectly adapting to 150m underwater working depth. It is widely used in marine detection, underwater equipment connection, underwater sensor signal transmission, and other precision underwater electrical systems.

Different from ordinary marine cables, this underwater signal cable adopts a customized foam filling structure to achieve accurate neutral buoyancy, ensuring the cable suspends stably in water without sinking or floating excessively. The durable PUR jacket provides outstanding water resistance, corrosion resistance, and tear resistance, while the twisted pair design effectively reduces signal crosstalk, guaranteeing long-term stable operation of miniature signal systems in harsh underwater conditions.

Core Product Features

Strict Neutral Buoyancy Design: Built-in foam structural layer realizes precise underwater neutral buoyancy, eliminating cable sagging and floating deviation, reducing underwater dragging resistance, and adapting to long-term suspension operation in 150m deep water.

2×26AWG Twisted Pair Copper Conductor: Adopts high-purity oxygen-free copper conductors with 26AWG standard wire gauge. The professional twisted pair structure effectively suppresses electromagnetic interference and signal crosstalk, ensuring high-fidelity transmission of weak miniature signals.

Dual-layer PE Insulation + Foam PUR Jacket: Premium PE insulation ensures excellent electrical insulation and low signal loss. The flexible foam PUR outer jacket features ultra-high water tightness, aging resistance, seawater corrosion resistance, and abrasion resistance, suitable for long-term underwater soaking.

300/500V Voltage Rating: Standard low-voltage rating meets the voltage requirements of most underwater miniature signal devices, sensors, and detection equipment, with strong electrical safety and stability.

Ultra-deep Water Adaptability: Professional underwater structural design supports a maximum 150m working depth, resisting deep water pressure and water flow impact, maintaining structural integrity and signal transmission stability in deep marine environments.

Lightweight & Flexible: Miniature cable structure with soft overall texture, easy to bend, lay and deploy underwater, suitable for narrow-space underwater equipment wiring and mobile signal connection scenarios.

FAQ

1. What is the maximum working depth of this underwater signal cable?

This cable supports a maximum underwater working depth of 150 meters, with excellent deep water pressure resistance and structural stability, suitable for long-term operation in deep freshwater and seawater environments.

2. Why choose neutral buoyancy design for underwater signal cables?

Neutral buoyancy enables the cable to suspend stably in water without sinking or floating, avoiding cable winding, pulling and signal jitter caused by water flow, ensuring continuous and stable miniature signal transmission for underwater equipment.

3. Is the PUR foam jacket suitable for long-term seawater use?

Yes. The high-density foam PUR jacket features excellent seawater corrosion resistance, aging resistance and waterproof performance, resisting erosion of seawater impurities and microbial adhesion, supporting long-term underwater soaking and stable use.

4. What signal types is this 2*26AWG cable suitable for?

It is mainly designed for miniature weak signal transmission, applicable to sensor signals, low-frequency control signals, monitoring data signals and other low-power precision signal transmission scenarios.

About Us

ADVANTAGES

Most ordinary marine signal cables lack precise buoyancy control, causing cable sinking, floating or winding in water, which affects signal stability and equipment operation. Our foam PUR neutral buoyancy underwater cable solves this pain point perfectly. The integrated foam filling structure realizes balanced underwater suspension, while the twisted pair shielding design reduces signal interference. Combined with 150m ultra-deep water pressure resistance and durable PUR waterproof jacket, it achieves longer service life and more stable signal transmission than conventional underwater cables, becoming the preferred choice for high-precision underwater signal systems.
