PROFESSIONAL marine load bank MANUFACTURER

Product Overview

Marine Load Bank is a heavy-duty, marine-grade waterproof and anti-corrosion dummy load testing equipment specially designed for shipboard power systems, marine generator sets, offshore platform power stations and dock shore power equipment. Different from ordinary land-based load banks, this marine dedicated load bank adopts salt-spray corrosion-resistant, waterproof and dustproof structural design, fully adapting to harsh marine environments such as high humidity, salt fog and wave splashing. It is mainly used for factory performance testing, shipyard commissioning, sea trial load verification, daily aging maintenance and fault diagnosis of marine generators and shore power systems, ensuring the stability, safety and reliability of ship-borne power equipment during long-distance navigation and offshore operation.

LINGDING ship dummy load bank series includes portable mobile type, cabinet fixed type and container high-power type, supporting mainstream marine voltage specifications such as 380V, 400V, 440V, 450V, 690V, with power coverage from 100kW to 50MW. It adapts to global 50/60Hz marine power frequency, supports resistive and resistive-inductive composite load modes, and complies with IMO marine environmental standards and ship inspection specifications. With IP56 high waterproof grade, strong anti-corrosion capability and continuous heavy-load operation performance, it is widely recognized by shipyards, marine engineering companies and offshore energy enterprises worldwide.

Core Product Advantages 

• Marine-grade Anti-corrosion & Waterproof Design The whole machine adopts marine heavy-duty anti-rust and anti-salt-spray paint process, with fully sealed IP56 waterproof and dustproof grade. The internal circuits and load components are treated with moisture-proof and anti-corrosion sealing, which can effectively resist high humidity, salt fog erosion and wave splashing in marine environments. It solves the problem of easy rust and short service life of ordinary load banks at sea, adapting to long-term offshore deck operation.

• Shock & Vibration Resistant, High Sea Condition Adaptability
Reinforced integral frame structure and shock-absorbing fixed design, effectively resisting vibration and jitter during ship navigation and offshore platform operation. The internal load modules are fixed with anti-loosening structure, ensuring stable operation without parameter drift or loose wiring under complex sea conditions, meeting marine mechanical vibration standards.

• Professional Marine Power Parameter Matching
Precisely matching global mainstream marine voltage 380V/400V/440V/450V/690V and 50/60Hz dual-frequency standards, supporting resistive and resistive-inductive composite load simulation. It can fully simulate the actual power consumption load of ship propulsion power, marine electrical equipment and deck machinery, accurately detecting generator power, frequency stability and load capacity, fully complying with ship sea trial and shipyard acceptance specifications.

• Long-term Heavy-load Continuous Operation
Adopts high-temperature resistant marine alloy load resistors with low temperature drift and strong thermal stability. Equipped with professional marine silent forced air cooling system and anti-blocking ventilation structure, it supports 24-hour uninterrupted full-load aging test without performance attenuation, meeting the requirements of ship long-time sea trial and power system comprehensive debugging.

• Multi-layer Marine Safety Protection
Built-in over-voltage, over-current, over-temperature, short-circuit, overload, phase loss, fan failure and sea-proof leakage multi-protection system. Equipped with waterproof emergency stop device and marine insulation wiring, it avoids electrical safety risks caused by marine humid and salty environment, ensuring zero-risk operation of ship power test.

• Intelligent Test & Customized Service
Supports local manual control, remote wireless control and upper computer intelligent control, automatically recording test data and generating standard marine test reports. Passed CE, ISO9001 and marine industry qualification certification, supporting customized power, voltage and special marine anti-corrosion specifications for special ship and offshore engineering projects.
