Product Introduction

PDK81301-5*0.75 水下电力电缆(5×0.75mm²镀锡铜,XLPE绝缘,TPU护套,深海大电流供电)

为深海ROV推进器、海底液压动力单元、大排量泵与海上钻井辅助系统设计的纯电力水密电缆,5×0.75mm²锡包导体压降小、载流量高,不含信号或光纤芯。XLPE绝缘耐热可靠;TPU护套专为长时间深海浸泡设计,耐水解、抗阴极剥离与海洋生物附着,同时抗磨、耐切割抗冲击,-40~105℃宽温域内自极地至热带海域均稳定工作。整缆径向水密,耐水压10MPa,适用于深水大推力推进与机械手、海底HPU、大容量泵等仅需高安培AC/DC供电的场合,结构可定制。

This product is a 5-conductor pure power watertight (submersible) cable, purpose-built for high-power underwater equipment operating at significant depths (such as deep-sea ROV thrusters, subsea hydraulic power units, high-capacity pumps, and offshore drilling auxiliary systems). It delivers high current capacity with low voltage drop, while maintaining robust watertight integrity and excellent resistance to dynamic bending in rough subsea conditions. This cable carries no signal or fiber cores, making it the optimal choice for applications that demand clean, high-amperage AC/DC power delivery alone under extreme hydrostatic pressure.

The TPU (thermoplastic polyurethane) jacket is specially engineered for prolonged deep-sea immersion. Unlike standard elastomers, this TPU formulation offers exceptional resistance to hydrolysis, cathodic disbondment, and marine biofouling adhesion, while retaining superior abrasion, cut, and impact resistance. Its reliable performance across a wide temperature range (-40°C to +105°C) ensures consistent operation from arctic waters to tropical seas.

Ideal for:

Deep‑sea ROV/AUV power tether for high‑thrust propulsion and manipulator systems

Subsea hydraulic power units (HPUs) and electric actuators

High‑capacity subsea pumps, compressors, and blowers

Offshore drilling equipment and blowout preventer (BOP) control power

Marine renewable energy – tidal turbine and wave energy converter power links

Shipboard heavy‑duty power feeds requiring watertight bulkhead penetration

Any underwater system needing pure 3‑phase or single‑phase high current (up to 35A) without signal integration, in extreme marine environments and without mechanical tension requirements

This cable is dedicated to high‑capacity 3‑phase power transmission under high hydrostatic pressure, eliminating signal conductors and minimizing overall cable diameter for easier subsea handling. It is a preferred solution for marine engineering, deep‑sea mining, underwater propulsion, and offshore energy distribution.
