Shipboard HV Power Cable

XLPE INSULATED COPPER-WIRE SCREENED FLAME-RETARDANT HIGH VOLTAGE CABLE FOR MARINE AND OFFSHORE

Engineered for the most demanding maritime and offshore environments, our cross-linked polyethylene insulated power conduit delivers uncompromising electrical transmission reliability. Designed specifically for complex vessel networks and offshore drilling platforms, this heavy-duty cabling ensures continuous operation even under severe mechanical stress and harsh weather conditions. The advanced XLPE insulation provides superior thermal stability and electrical performance, while the meticulously integrated copper-wire screening effectively mitigates electromagnetic interference, safeguarding sensitive onboard communication and control systems. Built with a primary focus on human safety and critical asset protection, the flame-retardant outer layers significantly reduce fire propagation risks in confined marine spaces. Forming the resilient backbone of modern marine electrical infrastructures, this solution guarantees stable power delivery across vast maritime installations.

Construction

The structural integrity of our marine high-voltage cables is the result of precision engineering and advanced material science. Each layer is carefully extruded and assembled to provide maximum flexibility without compromising mechanical defense. The core features tightly stranded copper wires, offering excellent conductivity and a smooth, consistent bend radius essential for navigating tight shipboard conduits. Surrounding the conductor, a semi-conducting compound screen works in tandem with the XLPE insulation to eliminate electrical stress pockets. We utilize non-hygroscopic fillers to prevent moisture ingress, ensuring long-term insulation resistance even in highly humid offshore environments. To meet specific project requirements, we offer extensive structural adaptability, including customized armor options such as tinned copper wire braiding for enhanced corrosion resistance or galvanized steel wire braiding for superior tensile strength. The outer sheaths are available in various polyolefin and PVC formulations, providing tailored defense against oil, abrasion, and UV exposure.

Standards applied

Compliance with rigorous international safety protocols is non-negotiable in maritime engineering. Our high-voltage power cables are manufactured and exhaustively tested to exceed the stringent requirements of global marine authorities. By adhering to comprehensive IEC standards for construction, flame retardancy, and material composition, we guarantee a product that performs safely under extreme operational loads. Beyond these baseline international standards, our manufacturing processes and final products carry prestigious type approvals from major global classification societies, including DNV, ABS, LR, BV, and CCS. This extensive certification portfolio ensures seamless integration into internationally flagged vessels and offshore platforms, providing project engineers and maritime inspectors with absolute confidence in the electrical system's reliability and regulatory compliance.

Cores identification

Efficient and error-free installation is critical during complex marine construction and refitting projects. To facilitate rapid and accurate connections in dimly lit or confined spaces beneath the deck, our high-voltage cables feature a highly visible and standardized core identification system. The distinct color-coding—utilizing stark black for single-core configurations and vibrant red, yellow, and green color tapes for three-core variants—allows electrical engineers to instantly identify phase configurations. This meticulous attention to visual clarity not only accelerates the termination and splicing processes but also significantly mitigates the risk of cross-wiring during critical system integrations. The color tapes are manufactured from durable, fade-resistant materials, ensuring that the identification remains clearly legible throughout the decades-long service life of the vessel.

Main characteristics：

Designed to endure the unforgiving thermal fluctuations of open-ocean environments, these cables maintain peak operational efficiency across a broad temperature spectrum. From freezing arctic routes to sweltering tropical deployments, the robust material composition ensures the cable remains flexible and structurally sound without cracking or degrading. Before leaving our facility, every cable spool undergoes rigorous high-voltage testing protocols, significantly exceeding standard operating voltages to verify insulation integrity and phase-to-phase isolation. This exhaustive quality control process guarantees that the power transmission network can safely handle unexpected electrical surges and sustained heavy loads without catastrophic failure.

Outer sheath color

The exterior defense of the cable is defined by its specialized black outer sheath, engineered specifically for the harsh realities of maritime exposure. This deep black coloration is not merely aesthetic; it is the result of specific carbon black additives that provide exceptional ultraviolet (UV) resistance. When routed across open decks or exposed offshore platform structures, the sheath effectively deflects solar radiation, preventing the polymer degradation and embrittlement that typically plagues standard cables. Furthermore, the smooth, low-friction surface of the black jacket facilitates easier pulling through complex cable trays and bulkheads, while its dense molecular structure offers a formidable barrier against chemical spills, salt spray, and abrasive physical impacts.

Application

The versatility and ruggedness of this high-voltage marine cable make it an indispensable component for a wide array of maritime and offshore applications. It is meticulously engineered for fixed installations across diverse zones, including exposed upper decks, internal passenger cabin routing, and the deep structural bowels of semi-submersible drilling rigs. In the event of a critical emergency, such as an onboard fire, the cable's advanced low-smoke, zero-halogen (LSZH) properties become a vital life-safety feature. Unlike traditional PVC cables, our LSZH variants emit minimal toxic fumes and opaque smoke, ensuring clear escape routes for crew members and preventing corrosive damage to sensitive electronic navigation equipment. Additionally, the specialized outer sheathing provides exceptional resistance to engine room oil spills, drilling muds, and continuous salt-laden moisture. Whether powering heavy lifting winches, main propulsion thrusters, or critical platform life-support systems, this cable delivers unwavering performance.

The cable is mainly intended for shipboard and offshore building to transmit electrical power.
