125℃ VW-1 energy storage battery cable material is specially designed for power energy storage systems and has excellent heat resistance and electrical properties.
Power energy storage system: used to connect the DC side connection cable between battery clusters and between battery clusters and converters, suitable for battery-to-battery connection, battery-to-inverter connection, BMS connection, etc. in mobile energy storage power stations, energy storage demonstration power stations, wind power energy storage systems, peak-shaving energy storage systems, etc.
Temperature resistance: The cable material is designed to operate in a temperature range of -40℃ to 125℃ to meet the use requirements of energy storage systems under extreme climatic conditions.
Flame retardant performance: It meets the flame retardant test requirements of the VW-1 standard to ensure that the cable can slow down the spread of flames in the event of fire and improve the safety of the system.
Environmental protection requirements: It complies with RoHS and REACH environmental protection standards to reduce the impact on the environment.
Chemical reagent resistance: The cable material can resist the erosion of battery acid and other chemicals and is suitable for the specific chemical environment of the battery system.
Electrical properties: Excellent electrical properties, including high breakdown electric field strength, low dielectric loss tangent tanδ, and high insulation resistance, ensure the safety and reliability of the cable when transmitting electric energy.
Flexibility and ease of installation: The cable material has good flexibility, which is easy to install and wire, especially in occasions that require frequent bending and movement.
Long-term outdoor use: The cable material is designed for long-term outdoor use and has good UV and ozone resistance.
Below are some cable products using this material in the market for reference (not necessarily all energy storage harnesses, but the technology is similar):
4/0AWG Single Core XLPO 125℃ Cable: High conductor cross-section, suitable for high current paths.
16AWG 3C Braided Shielded XLPO 125℃ Cable: Three cores, with braided shielding, used for signal + power combinations or more complex circuits.
12AWG Single Core XLPO 125℃ Cable: Suitable for medium current, high temperature laying.
When selecting a cable, pay attention to: confirming that the conductor cross-section (mm² or AWG), rated voltage, whether shielding is required, outer diameter, bending radius, and other parameters meet the design requirements of your energy storage system.
Manufacturer Formulation Differences: The formulation of XLPO material from different manufacturers (type of flame retardant, crosslinking method, additives) will affect its performance. Refer to specific documentation during the design process.
Certification: It is recommended to choose wires with UL, ISO, TÜV, and other certifications to ensure safety and long-term reliability.
Processing Considerations: Cross-linked wires may have higher hardness or rigidity during welding and terminal crimping, which needs to be considered in the process.
Testing: It is recommended to perform thermal cycling tests, aging tests, and short-circuit/high-temperature tests during the prototype stage to verify its stability in energy storage systems.
These characteristics make the 125℃ VW-1 energy storage battery cable material an ideal connection solution in power storage systems, especially in occasions that require high temperature resistance and high safety.
