UL3311 Boat Battery Cable is a UL-listed flexible power cable. It uses stranded bare copper conductors with EPDM insulation, giving it excellent resistance to both high and low temperatures, oil, and corrosion. The cable also meets the VW-1 flame retardant standard. It's commonly used in boats, vehicles, industrial motors, heavy equipment, UPS systems, and similar applications where you need a reliable, tough electrical connection in demanding environments. It's fully RoHS compliant as well.

Application
Low-voltage power supply for automobiles and special vehicles
UL3311 Boat Battery Cable is commonly used as a battery connection line for heavy vehicles and engineering vehicles, for connecting the starter motor, grounding terminal and the battery. Its characteristics of withstanding high and low temperatures, resisting oil/ozonization/damage, can cope with the harsh conditions of the engine compartment. In equipment such as electric forklifts and airport ground service vehicles, it is also used for the DC wiring of the battery pack and the electrical control system, ensuring stable power supply under frequent start-stop and vibration environments. At the same time, it complies with the vehicle-mounted flame retardant VW-1 standard, enhancing safety.
01
Industrial motors and equipment power leads
In industrial automation production lines, UL3311 Boat Battery Cable is the preferred wire material for motor winding leads and frequency converters. Its highly flexible design is suitable for compact installation spaces and wiring of moving parts of equipment. The EPDM insulation is resistant to chemical corrosion and can withstand erosion from factory oils, cooling fluids, etc. For example, in the wiring of water pumps, compressors, and conveyor belt motors, it can withstand a working temperature of 90°C for a long time, reducing the risk of high-temperature aging, and with a 600V rated voltage, it meets the insulation requirements for industrial control circuits, ensuring the continuous operation of the equipment.
02
Power supply for welding equipment and heavy machinery
Due to its high conductor current-carrying capacity and resistance to mechanical damage, UL3311 Boat Battery Cable is commonly used in the secondary side cables of welding machines, connecting the welding gun to the main unit, and is suitable for handling large current instantaneous impacts and frequent dragging. In heavy equipment such as mining machinery and construction cranes, it is used for power distribution and power supply to the actuating mechanisms. Its wear-resistant insulating layer can withstand physical damage such as stone impacts and friction, and its halogen-free property reduces safety hazards in confined spaces.
03
Backup power supply and industrial UPS system
In UPS systems of key facilities such as data centers and hospitals, UL3311 Boat Battery Cable is used to connect inverters with battery banks and distribution cabinets, ensuring seamless power supply during power outages. In the wiring of backup battery banks in telecommunications base stations, its weather resistance can adapt to the temperature and humidity fluctuations of outdoor enclosures, its low resistance characteristic reduces power loss, improves the conversion efficiency of the backup power supply, and ensures the reliability of the standby system.
04
Strong power wiring inside large household appliances
Commercial kitchen equipment such as large ovens, freezers, and industrial washing machines typically use UL3311 Boat Battery Cable for the power supply lines of their internal heating elements and compressors. The EPDM insulation has heat resistance suitable for the high-temperature environment inside the equipment. Its resistance to steam, acids, and alkalis enables it to cope with humidity and chemical corrosion, meeting the safety and lifespan requirements for internal wiring in household appliances. Additionally, it is RoHS compliant and meets environmental protection standards.
