UL 3644 Wiring: Wiring for Energy Storage Equipment Power Facility Scenarios as a 'Safety Guardian'

This model of wire can be used for auxiliary circuit connections inside energy storage battery modules. For example, the supporting power supply lines for temperature monitoring and voltage sampling between battery cells in the module, as well as the charging and discharging of energy storage batteries, generate heat. Especially when large capacity modules are densely arranged, local temperatures are prone to rise. Its 200℃ temperature resistance can prevent damage to the lines due to high temperature aging; At the same time, it can also connect to the balancing circuit components inside the module. The 1000V withstand voltage performance can adapt to the voltage requirements of the balancing circuit during operation, ensuring balanced charging and discharging of battery cells and extending the overall life of the battery pack. In addition, the connecting wire between the battery module and the small protective components on the module bracket can also be used to adapt to the relatively small installation space around the module.

As the core equipment for power conversion, energy storage inverters generate a large amount of heat when their internal power devices work. UL AWM 3644 wires are suitable for wiring their internal high-voltage and low current circuits. For example, the connecting wires between IGBT modules and driver boards in inverters, as well as the auxiliary power supply lines for filtering inductors, capacitors, and other components, can withstand the high temperature environment caused by power device heat dissipation, and ensure circuit safety at 1000V voltage level with good electrical insulation performance, avoiding short circuit faults caused by insulation failure. At the same time, its soft and easy to bend characteristics are also suitable for the dense component layout inside the inverter, making assembly and wiring convenient.

This wire can be used for wiring auxiliary control circuits and monitoring circuits in energy storage combiner boxes and distribution cabinets. The busbar inside the combiner box is responsible for collecting the current of multiple groups of batteries. The connecting wires between the temperature and current monitoring sensors and the control module can be selected with this type of wire to adapt to the local high temperature generated during the combiner process; The coil power supply line for small relays, contactors and other control components inside the distribution cabinet can also be used. Its 1000V withstand voltage can cope with voltage fluctuations inside the distribution cabinet, and the flame retardancy of silicone rubber (in accordance with UL FT2 testing standards) can reduce the risk of fire in case of circuit failures, ensuring the safety of the energy storage power distribution process.

The auxiliary power supply and temperature control system related circuits of energy storage devices often use this wire. On the one hand, the auxiliary power supply unit in the energy storage system that supplies power to the control module and monitoring instruments can be used in its internal circuits to adapt to the medium voltage and heating conditions during the operation of the auxiliary power supply; On the other hand, the power supply connection wires for temperature control devices such as cooling fans and small water-cooled circulation pumps of energy storage equipment can withstand high temperatures near the heat source area of the temperature control device. At the same time, their good weather resistance and chemical stability can cope with the long-term wear and tear of the equipment, ensuring that the temperature control system continues to cool down the energy storage power facilities and maintain the normal operating temperature of the equipment.
