Product Advantage
With an oxygen index ≥32%, it passes GB/T 2408-2021 horizontal burning test (burning time ≤30s, no drips). Its flame retardancy is 23% higher than ordinary woven fabrics (oxygen index ≤26%), quickly blocking high-temperature fire risks of battery boxes. It provides core safety for woven fabric protectors for energy storage battery boxes, meeting fire safety requirements in power stations and residential areas.
Tested to IEC 60529 standard, it has a 100% barrier rate against rain (no leakage after 30min continuous spraying) and dust (no intrusion in level 8 sandstorms). It prevents short circuits caused by rainwater infiltration and heat dissipation issues from dust accumulation, reducing the failure rate of battery boxes in rainy and sandy areas by 60%, highlighting the durability of outdoor energy storage protectors.
With a temperature range of -30℃ to 90℃, it remains flexible (no cracking or hardening) at -30℃ and retains ≥85% tensile strength at 90℃. Its applicable range is 150% wider than traditional PVC protectors (-10℃ to 60℃), coping with severe cold in northern winters and intense sun in southern summers, meeting outer protection needs of energy storage battery boxes in different regions.
With longitudinal tensile strength ≥18kN/m and tear strength ≥1.2kN, it absorbs over 65% of impact force from scratches or sandstorms, avoiding box deformation. The wear-resistant coating (≥500 wears/200g load) resists gravel scratches, extending the service life of woven fabric protectors to over 5 years.
Weighing only 150-200g/㎡ (1/8 the weight of metal covers), one person can install it on a battery box in 10 minutes, 300% more efficient than metal covers. The 30-50m roll design allows on-demand cutting (loss rate ≤3%), significantly reducing labor and material costs for energy storage battery box protection.
Added with 0.5% UV stabilizer, it retains ≥80% tensile strength after 500h xenon lamp aging test, with no obvious fading or embrittlement. Its outdoor service life exceeds 5 years, 150% longer than non-UV-resistant protectors (≤2 years), reducing replacement costs for energy storage station protectors.

Product Uses
Applied to battery boxes in ground-mounted PV stations, woven fabric protectors with IP65 waterproof grade block rain, dew and sand. Their UV resistance (≥80% tensile retention after 500h xenon test) withstands long-term sun exposure, ensuring battery boxes work stably in open areas, reducing maintenance caused by environmental corrosion.
Used for battery boxes in wind farms (often in remote areas with strong winds), woven fabric’s ≥18kN/m tensile strength resists wind-driven debris impact. It also tolerates -30℃ low temperatures, avoiding brittleness in cold plateaus, perfectly matching the harsh working conditions of wind energy storage.
For battery boxes on mobile energy storage trucks (used for emergency power supply), lightweight woven fabric (150-200g/㎡) reduces vehicle load. Its anti-tear property (≥1.2kN) copes with vibrations and bumps during transportation, protecting battery boxes from damage without affecting vehicle mobility.
Fitted on small battery boxes of residential rooftop PV storage systems, woven fabric is easy to install (single-person operation). Its flame-retardant feature (oxygen index ≥32%) meets home safety standards, and the neat appearance blends with residential environments, balancing protection and aesthetics.
FAQ
Q1: Can this woven fabric protector be cut to fit irregularly shaped battery boxes in mobile energy storage vehicles?
A: Yes. It’s highly flexible and supports on-demand cutting. The 30-50m roll design ensures minimal waste, and it fits tightly to irregular shapes without affecting its waterproof or flame-retardant properties.
Q2: How often does the protector need replacement when used in sun-exposed PV energy storage stations?
A: With UV stabilizers, it has an outdoor service life of over 5 years. Annual inspections for wear are recommended, but replacement is only needed if tears or strength loss (below 80% of original) occur.
Q3: Will the IP65 waterproof performance decrease after long-term exposure to heavy rain in coastal areas?
A: No. It undergoes strict marine-grade waterproof testing; heavy rain or salt spray won’t reduce its waterproofing. After 3 years of coastal use, IP65 grade remains intact.
Q4: Can it be used with anti-corrosion coatings on battery box surfaces without affecting adhesion?
A: Yes. Its surface texture won’t interfere with coating adhesion. It can be installed directly over cured anti-corrosion coatings, enhancing protection without compromising the coating’s effectiveness.
